I just picked up the Utopia series 2 soundtrack album on Record Store Day. I have to admit that I don't like all of the music from the brilliant Channel 4 TV series. Some of the more uptempo cues veer on the wrong side of cheese for me and those off beat chords always make me think of bad reggae, BUT all of that can be forgiven due to the absolutely astonishing amount of programming and sound design that really makes this soundtrack shine. There are so many off the wall and unexpected sounds that creep in to every cue, twisting and mutating like the story it underscores - a truly original piece of work. Fragments of voices (sampled voice is used heavily throughout the work), manipulated choir, squelchy bass lines, found percussion and loads of distortion feature throughout, but it is the more subtle cues that really standout for me.
Vinyl copies are pretty scarce (It was released as a limited edition issued for Record Store Day), but if you search hard enough I'm sure you'll uncover a copy.
