What's this song about? It's about building stuff up I guess. Whether it's with Lego or literally whatever other construction material you can think of: it's fun to build things. Really fun. Anything. You could be an office block contractor – I bet it's still fun to see skyscrapers grow into the sky; or even someone who makes music. It's fun to build!

And that's illustrated in the music of Kero Kero Bonito. It is fun, it sounds fun; the lyrics are fun. But that's not the point, the point is the architectural collage of the production, an edifice itself, moving from squelch-bleeps of the first verse to a beat-heavy mélange of drums and washing cymbals to the second. And most of all in the last quarter or so of the track, where the vocals from Sarah (the singer) get sped into infinity and into a orbiting satellite of sounds, collected as all the fun electronic sounds of humanity and sent up into space, just in case any aliens wonder what we're about or who we are. We are squidgy and flute-sounding, bleepy and glittering, percussive and blissful, euphoric and tropical, fun and fanciful.

It feels as if it marks a step forward for KKB – for me it's the catchiest they've been, but at the same time it's the most experimental they've been, what with their dadaist collage of noises, the pitch-shifting and tempo-increasing; it feels like they've already found their feet, now they're having fun using them for interpretive dance and skipping around. You can actually buy the track on iTunes.

Don't know what the hell I'm talking about? In that case you have to check out Kero Kero Bonito's mixtape, Intro Bonito. And if you'd like to see this lovely lot live, then you'd better get yourself some tickets for a show they'll be playing at Electrowerkz, London, on 3rd December.

Oh: We also interviewed Kero Kero Bonito. (They're as fun as their songs!)
