Got a real "big room" feel going on, the drums sound distant, like you're miking a live setup from about 2/3 back of the auditorium. It's a cool party ambience... Tempo is kinda loose, but it's really sort of an improv jam piece anyway, so it's not really much of a detraction. On the plus side, each part has a place in the soundfield; it'd be pretty easy to have something like this sound cluttered and crashing about; but this doesn't at all.
Kinda fun! I'm actually liking all the stop-start for some reason. It's part of the ambience...
