There are much tricky arragements in rhythms and a lot of sound variations in it, that's really an astonishing work. In my opinion the best piece is B1 "Past The Gates" (the tracklisting here is currently wrong). Contains well made experimental sounds... An album with influence of several music genres and that is fine!
Quite possibly one of the best records I've ever heard. Didn't like it at first, but bought it anyway. Then, on a a whim, I listened to it and it blew my mind. An acquired taste, but way ahead of its time, considering that it was recorded in 1995-97. Must have for all psychonauts.
