Here's the story: King Roc wrote dance music, once. He's half of the wildly successful techno / deep house duo Two Armadillos with Giles Smith of UK club pioneers Secretsundaze. He DJs Brazil, China, Australia, a couple of times each year each as well as regularly playing the big European and UK clubs. He lives in Brazil and Berlin but really he's a nicely-mannered gent from southwest London. And he's carved out quite a job reinterpreting big names from Future Sound of London to New Order to S-Xpress to new blood like D-Nox and Beckers.

But he doesn't like to talk much, and two years back he was fed up to the back teeth of 4/4 for the dancefloor. So when he met Australian artist Seb Godfrey of Drunkpark, they hatched a plan together.

A concept album that won't explain itself.

(But it started with some ideas about dreams, intuition, happenstance and coincidence.)

No talking. Big secret theories. A concept album.

Starting with: A set of four collectable 12"s (each with a lovely poster!) Artwork by Seb, each 12" with its own theme - the first of which was "chance". Music by King Roc - but the 12s had to run from ambient to trip-hop to indie to Orbital-style oldschool to techno.

And then: for the final CD, each track had to be ripped apart and thrown back together for its reappearance on the CD - with trip-hop transformed into a beautiful vocal number, or techno into lush, beatless cinematics.

Voila - the CD you have now, Chapters.

The hype has been building for some time now round the 12"s and their visuals - an increasingly rare, non-disposable approach to vinyl that King Roc paid for from his own pocket. "They're the best thing King Roc has ever done" - IDJ. "[This] will be the year King Roc claims his crown ... [the 12"s are] dreamy ... elegant ... gorgeous ... bittersweet ... melancholy" - DJ mag. And that's alongside the more experimental names raving about his Two Armadillos work, like Agoria calling it "perfect for summer days".

What's the concept for the album? - You can explain these things, says King Roc, but it sounds arrogant. The questions have to be more important than the answers. There's some maths in there [Phidias Gold is sequenced to follow the timing of the "Golden Ratio" of intervals of 1.68], there's a dream about an enormous plant made of brick that inspired the entire fourth EP, Dreamattic, and Flow is about those few times in life when you are totally ego-free and entirely in the moment.

There are only chapters in a person's life...
