I only ever really follow the music, that's what I'm about, I don't think about it too much. I just wanted to make a piece to sleep through, to sort of explore that sleeping space as a listening space and to have a different encounters between our listening minds or hearing minds and music. I think that's really interesting. After that I feel I've done my job.

If there's loads of material going by you don't notice the individual things quite so much. Also it really foregrounds the sonic dimensions like electronic ambient music, it's pushes all of that colour to the foreground so you hear little every atom of sound.

I'm obsessed with low end, its kind of my religion. In a way it has given me a chance to explore more than I have in any other project.

I've always written at night - my working day for years was around 9pm to 2am - though I do keep more regular hours these days.

There is also a particular area of sleep called slow-wave sleep. I immediately liked this idea. It turns out this part of sleep is where the brain basically gets into step with itself and gets into this one single phase of these relatively slow brain waves - around 10 Hz or so - and the whole brain 'fires all at once'. This is a brilliant bit of sleep where we consolidate memory and learning, and memory is one of my obsessions really.

In terms of how the music developed, it was my normal process, which I would say is really a hybrid process of sketching on bits of paper, playing the piano, playing synthesisers, using the computer, staring out of the window, finding things I'd forgotten about, happy accidents, failed plans, best intentions, equipment failures. It is a multidimensional process incorporating a lot of planning and intention and a lot of randomness. Ultimately I just follow the material where it wants to go a lot of the time.
