"Autochaos" by Nashi Dela
I don't know much about this group other than what I've gleaned from their MySpace (they're based in Switzerland, sing in Russian, have released one album), but I must say: I like them. The music is seemingly improvised and consists of rich, chaotic smatterings of bass clarinet, trumpet, bass, various electronics, and only they know what else. "Autochaos" is a relatively heavy track that pulses along then devolves then pulses again. Some Russian sprechgesang fits over the top to lighten the otherwise very dense mix, and the result is one of Nashi Dela's more "fun" songs.
