In short
Song Exploder dissects “Crystallized” by The xx, focusing on how the band formed, wrote, and recorded the track, plus what it means emotionally.
Guest backgrounds
Rami Croft (guitar, songwriter, vocals), Oliver Sim (bass, vocals, songwriter), and Jamie xx (producer/electronic live performer). They met as children (nursery school at 3; Jamie at 11) and later formed The xx in high school; Jamie joined the band and helped translate their quieter live sound into electronic performance.
Key claims
“Crystallized” began as live-playable parts built around MPC-driven electronic drums and sparse guitar/bass arrangements. The intro sound came from experimenting with an MPC and recording Oliver’s “ooh” note. Vocals were recorded together in stems.
Notable examples
lyrics inspired by compressing ashes into diamonds; “rumbled/tumbling” drum ideas; demo versions with Diplo and Lex; the “go on slow” refrain as a compromise between avoidant/anxious intimacy.

It won the prestigious Mercury Prize and was named one of the best albums of the year by Rolling Stone, Pitchfork, and more. And since then, The Guardian has named it one of the best albums of the 21st century.
3:25Jamie xx:This year, the three band members, Rami Croft, Oliver Sim, and Jamie XX, played together as the XX for the first time in eight years. I spoke to them in between the weekends at Coachella, where they were opening their sets with the song Crystallized. It's the first song that they ever released, back in April 2009, when the lineup also included Barya Koreshi on guitar. I spoke to Rami, Jamie, and Oliver here at my studio about how they first found each other and how they made Crystallized.
4:11Oliver Sim:I'm Jamie, I'm the producer and I do all the electronic stuff on stage
4:16Romy Croft:I'm Romy and I play guitar and I'm one of the songwriters and I sing
4:21Oliver Sim:And I'm Oliver, I play bass, I sing and I'm the other songwriter.
4:29Romy Croft:Oliver and I met in nursery school when we were three.
4:33Oliver Sim:And then we met Jamie when we were 11, the first day of school. I didn't know anybody else that came from my previous school, so I was on the hunt for some friends quickly. and I gravitated towards these two quite instantly. I just felt like some kind of similarity, like a strangeness probably that I felt similar to.
5:01Romy Croft:This is wonderful, fascinating to hear this now. Jamie and I used to go skateboarding together and we used to watch a lot of skate videos together and discovered a lot of amazing music. There was a video that Jamie showed me that had Portishead and Mazzy Star and The Cure. I think that was actually an amazing way of discovering music.
5:20Oliver Sim:And then my uncles were DJs, so I inherited my decks when I was 10 years old, playing records, playing my parents' records. And then I learned about the sampling of those records and all of that. We didn't really start making music together. Like, we started independently. Jamie was making his solo music. Romy was making hers. as I was making mine.
5:44Romy Croft:It was just such a private, personal exploration, connecting with music. It was such like a shy... I remember a moment of us sitting together, and I was like, I like singing. And you were like, I like singing.
5:59Romy Croft:Then Oliver and I were kind of trying to, along with Baria, who was also in the band at the time, trying to find a way to play live.
6:08Oliver Sim:We were gigging me, Romy, and Baria for quite a while. so for a period of time I was watching these guys do it and going to the gigs.
6:18Romy Croft:Yeah we begged Jamie we said please play drums in the band please play live drums because he was a great drummer.
6:24Oliver Sim:I didn't really know what to do because I didn't want to play drums on it because it sounded so good as it was. It wouldn't have worked because these guys were a lot quieter than they are now you just wouldn't have been able to hear what was going on on stage if there was a live drum kit that was one of my main things that was stopping me from doing that i'm really glad
6:42Romy Croft:that jamie said no at first because it kind of forced oliver and i to we figured out a way to make electronic drums simplistic ones first and i think because of the limitations i mean a lot of everything we'll say has probably come from limitations as you know oliver and i were like writing to electronic drums from the eight track that i had it had like drum beats in it so we sort of would use those or i remember making some really simple drum beats on like a weird program on drummer on my computer what is that program like hammerhead or something yeah very basic i really remember that and then just we had that burnt it on a cd and then we gave it to the sound person and said like have to be like track three and it would go like one two three eventually we said to jamie please can you can can you like help us and make some beats so you I made some beats and then eventually...
7:31Oliver Sim:Eventually I went on stage and started playing the MPC.
7:34Romy Croft:Having Jamie play the MPC live in the band was a very big turning point of the fluidity of it being live feeling, but still electronic.
7:50Oliver Sim:And MPC is a music production centre, that's what it stands for, and it's actually meant for making full tracks on them, usually hip-hop but i never did that because i always just wanted to use it as a live tool playing it live tapping the buttons i think when we started writing crystallized we only had about four songs you know we were playing pub sets for about 20 to 25 minutes and jamie had just joined the band i remember the very like earliest demo was rommy and i playing two acoustic guitars
8:38Romy Croft:it was in front of um the program on photo booth photo booth the most roundabout way yeah it worked though we'd like filmed ourselves there was the video and then you could extract the audio
8:58Oliver Sim:At that point, songs very much started as like words on a piece of paper.
9:04Romy Croft:We sort of used to share lyrics back and forth, like poems.
9:07Oliver Sim:I remember my first lyric was inspired by something my mum read in a paper about how you can have your ashes compressed so hard that they are turned into diamonds, which is really macabre but that's the first lyric you've applied the pressure to have me crystallized you've applied the pressure to have me crystallized and you've got the faith that I could bring paradise
9:45Romy Croft:those first lines of crystallized you know I thought they were so visual and really unique but then I think I sort of reacted then I'm sort of in my second verse trying to write something that is got a similar pattern and wanted to use an interesting word like crystallizer there's like paralyzed and you know other words that kind of bouncing off what Oliver had said I'll forgive and forget Before I'm paralyzed Do I have to keep up the pace To keep you satisfied
10:23Oliver Sim:Mine and Romy's writing was very much like a patchwork rather than like sat in the room together but so many of the songs from the outside must really sound like we're singing together, you know, two parts of a love song sang at each other. You know, Ron and I being best friends and not only that, both being gay. You know, it's not directed at one another. It was kind of making each other's perspectives kind of just hoping they would fit.
10:59Romy Croft:Sort of a shared space, both individually saying our perspectives on it, but never really asking like, ooh, what's that about for you necessarily? Just reacting to each other's lyrics. Then you could sort of like create things and then send it back and forth between each other, have that distance from each other, but the closeness. Yeah, that autonomy to be able to make things separately was a big thing for me. And the way Oliver and I sing together kind of comes from a place of like, oh, you go first, no, you go first. So then we sing together.
11:37Oliver Sim:The first time I really remember was us trying to figure out what the song was and how to play it live, probably for that weekend's show. I was also trying to figure out my new toy, which was an MPC, and plugged a microphone into it and got Oliver to sing like an ooh, just a note, just to see how it worked, and then recorded it into the machine and started messing with the pitch live, and that became the intro of Crystallized.
12:11Oliver Sim:So that sound is still that same sound from that first day of just trying to work out Crystallized.
12:17Romy Croft:It really feels like it's such a deep dive into memory to remember the creation of this song. I know that in terms of my personal connection with playing the guitar, I've never really been that interested in full chords. I really love melodic guitar.
12:39Romy Croft:But wanting to be able to sing confidently and play the guitar, there was a simplicity to the instrumentation of it. because a lot of what we wanted to put on the album was exactly what we could play live. And I wouldn't feel confident to play that full intro riff and sing. I had to move to just running single notes. You don't move slow And taking steps in my direction The sun's on's echo Does it lessen your affection?
13:19Jamie xx:My conversation with the XX continues after this.
13:26Jamie xx:Song Exploder is sponsored by the game Mixtape. And to learn more, I talked to one of the creators. My name is Johnny Galvatron. I'm the writer and director of Mixtape.
13:35Oliver Sim:It's about three teenagers on their last day of high school going to their final party together, listening to the greatest mixtape of all time.
13:43Jamie xx:And where did the idea for this game originally come from?
13:45Oliver Sim:Just wanting to make a game based around That's Good by Devo, which is the greatest song of all time. There's just something alive in that song that speaks to me. And it's very much a game about being a music lover and someone who appreciates music and knows where to place it in their life. And then game-wise, there are different kinds of mechanics. There's different kinds of music. There's different kind of art style. So the game as a whole should be viewed as a mixtape and kind of this artistry of arrangement.
14:14Jamie xx:And so how is the game itself like a mixtape?
14:17Oliver Sim:So usually in a video game you will have a standard set of mechanics which might be fighting. But in a mixtape there's different people saying different things with different vibes. And you want each song to be given its own experience, its own life. And you want to use the medium. That's what's kind of important about making video games. You want to use the medium to show what the music is showing. We have this song BJ Thomas most of all where a friend gets betrayed and she floats back through town and just kind of knocks everything out of her way as she flows through town and you control her and like what a beautiful way to kind of use that song and to use a mechanic and input to show the betrayal and the despondency and the sadness and when you can get all those things mixed together and hit those crescendos where you hit between video game, music, narrative, of that's the gold, that's the diamond that you aim for.

17:25Oliver Sim:When it came time to record this song, we'd actually done a few different versions with different producers. like our label and management had set us up on like different speed dates like we had done a version of the song with diplo who is the most exciting person ever to us and i think we'd done another version with a producer called lex but it wasn't quite right because i think you know the space in the music often ended up being filled by that person's like sound and their signature especially because we were all so young we didn't really you know know what we were doing but it felt like we were just you know handed over to these different people we all just really loved
18:11Romy Croft:the sound of the demos they just had like our feeling of the live show and we were just like we'd hear some of the versions back and be like oh we just like how the demo sounded before and then you kind of get people saying oh but this is you should work with them because you know they've done this and I think we were all just quite like oh we don't really bothered about that we just
18:31Oliver Sim:want it to sound like us it was really useful to have gone through all that and hear all the different ways that things could be filled out and I was learning a lot at the same time but definitely the back of my head I was like I could do this we didn't think it was an option for Jamie to produce until we had worked with other people and then XL employed Roddy McDonald to be the engineer at their new studio which was just in the garage of the headquarters of xl and that sort of opened the door to the possibility of maybe me being able to do it because he had all of the engineering skills it kind of gave me the opportunity to try and prove myself and i remember
19:16Romy Croft:feeling excited at the idea of jamie doing it because i know he would keep it sounding like us
19:21Oliver Sim:Everything was so exciting. We had this space for free. We'd worked out how to do all these songs structurally because we played them live so much. It was the MPC stuff first, so that the groove was right to record the guitars over. And I just literally played it in like I would in the band.
19:49Oliver Sim:so I was playing it live just do the whole thing in one go we were all talking about rumble drums which is a term I think we just made up yeah from listening to a few different bits of music it's those tumbling rumbling drums I remember you like tapping on a table to kind of like get the idea across I was working out how to make electronic production feel live and feel organic trying to work out how to make every click every rim sound slightly different like it would if you were just hitting a snare so it was like painstaking and I play on the guitar
20:33Romy Croft:and then Baria plays the second guitar part and then Oliver joins with the bass.
20:54Romy Croft:It's interesting to me how sparse the verses are.
21:03Oliver Sim:There is just always a part of me that winces when I listen back to that because I almost don't recognize that person. It has an element of like finding like an old diary from being a teenager. You know, that is not how I sound today. When we recorded that, I was 18 and I'm 36 now. So I'm 18 years later. Wow. When we were kids, their voices sounded, if you were to pitch one up or one down, and they would sound exactly the same.
21:36Romy Croft:I like to think that we learn to speak at a similar time. You know, we grew up together learning, so I like to think it's kind of interwoven with that, that we sing in a similar way.
21:46Oliver Sim:So don't think that I'm pushing you away When you're the one that I've kept closest Hi, hi, hi
21:57Romy Croft:Hi, hi, hi I feel like that's a melody that Oliver brought to the song. there's quite a lot of that in I realised in our first album I don't know what it is it might have
22:08Oliver Sim:just been that those are the moments where you play the more complicated guitar parts so you can do the words at the same time quite possibly yes
22:25Romy Croft:I kind of love the playfulness of it just being a free melody that like doesn't have words and people can sort of sing along with it.
22:32Oliver Sim:And that particular time I was really obsessed with not using any pre-made sounds. So every sound is sampled and layered from records that I owned. And that was just fun for me.
22:47Romy Croft:In theory, I think we've talked about doing the vocals at the same time, but I don't know if we actually, you know, I remember being a conversation of it being like a nice idea that we've sort of recorded everything in live. I think that was aspirational because it had been written live, but I don't think we ended up doing that in the end.
23:03Jamie xx:Oh, let me play you Oliver's vocal stem because you can hear Rami singing in the background, being picked up by his mic and vice versa.
23:11Romy Croft:Does it lessen your affection?
23:14Oliver Sim:No, you say I'm foolish. So we did sing it at the same time. Yeah. Oh, that's a nice discovery. Nice.
23:24Romy Croft:Thank you for showing us this.
23:45Romy Croft:There's a part towards the end of the song where we sing our individual parts that are different over each other. Singing our pre-choruses.
23:53Oliver Sim:Mine is things have gotten closer to the sun and I've done things in small doses. So don't think that I'm pushing you away when you're the one that I've kept closest.
24:03Romy Croft:And mine is glaciers have melted to the sea. I wish the tide would take me over. I've been down on my knees and you just keep on getting closer.
24:12Oliver Sim:Glaciers have melted to the sea I wish that I'd been taking me over So don't think that I'm pushing you always And you're the one that I get closest Go all slow
24:29Romy Croft:It's still now one of my favourite parts and we've just performed it, but I have to block him out completely in my mind and just sing my part and not try and think about what you're saying because I'll start singing your part. But that I kind of look back on fondly. It's like, that's an interesting decision that we did that. And I love it now, but do you remember why we did that?
24:49Oliver Sim:You know, in hindsight, The song to me is the avoidant and the anxious. And that moment feels like a moment of conflict with the resolution of coming back together and singing in unison. The person in the relationship that feels scared of intimacy takes a step back. And then the other person in the relationship who feels scared by that step back takes a step forward. and that kind of like cat and mouse chase which is all too frequent because I think those two characters often attract one another and without you know getting too therapy and personal you know I definitely relate to that anxious role and yeah I kind of see very much this song as like a tale of those two characters, but with a resolution and a compromise of, you know, that final refrain of just go slow.
25:55Oliver Sim:You know, it's not that I am not in this. It's not that I don't care, but you're going to have to match my kind of speed and how we do this relationship.
26:14Oliver Sim:This album to me is peering into other people's relationships and building my own expectations and my own fantasies and excitement about it I felt such an embarrassment that I hadn't been in love like it made the songs less honest or less vulnerable but it was still such a personal thing for me to share my kind of like fantasies and my feelings I think Romy grew up a lot faster than I did and and you know you were writing from more of a place
26:52Romy Croft:of experience I think I have always been drawn to romance and the euphoria of that and the heartache of that and I think that I was writing from some experience at this time still very early early love and lust and longing but I think we definitely spoke about it not being so specific without time place or gender I think this song for me feels very open to interpretation which which I love
27:28Romy Croft:we've all grown up together literally from a young age and throughout this band and throughout this process and i feel very nostalgic hearing this song again and it's really lovely to be able to talk about it you know we've been relearning how to play all this old music and going into the projects and the stems and like reconnecting with the decisions we were making then and i've actually really enjoyed that as we are working on a new album to just reconnect with those decisions and that sort of naivety and the simplicity of that time and I think it's nice to learn from ourselves again when you say it's half our life okay that template does bring up it's I can't believe it's been that long and I'm so grateful to be able to still play this music
28:23Jamie xx:And now, here's Crystallized by the XX in its entirety.
28:53Let's go.
29:20Romy Croft:Forget before I'm paralyzed Do I have to keep up the pace To keep you satisfied?
29:34Oliver Sim:Things have gotten closer to the sun I've done this in smolosis So don't think that I'm pushing you away When you're the one that I've kept closest High-yay-yay High-yay-yay High-yay-yay High-yay-yay You don't move slow
30:07Romy Croft:And taking steps in my direction
30:12Oliver Sim:The summer sounds echo Does it lessen your affection? No You say I'm foolish For pushing this side But now I want you to lie I, I, I The sea has a mountain to the sea I wish the tide would take me over I've been down on my knees And you just keep on getting closer Aye-aye-aye Aye-aye-aye Aye-aye-aye Aye-aye-aye
31:11Oliver Sim:I've been down on my knees When you're the one that I get closest Go on slow Go on slow Go on slow Go slow Go slow
32:29Jamie xx:Thank you. Rishikesh Herway. Thanks for listening.
