Ambient free improv, led by tuba (in heavy electronic processing for deep, echoey sounds) plus other instruments. Stuart Dempster adds trombone, didgeridoo, etc. Eric Glick Rieman is on prepared electric piano, which comes off like percussive wood or metal. Instrumental, FCC clean.

1- (34:08) Opens with low, cavernous tuba: An expansive, glacial wash of sound with occasional high groans like sea lions. BIG. After 7 minutes, the other instruments move in: more active, but still a big heavy atmosphere.
Any segment will make for a good excerpt, but you'll want to catch the first half for the noisier, darker background, or the segment around -15:00 onward for some percussion clatter (prepared electric piano!), or -10:00 onward for some slow, twangy horn soloing.

2- (6:26) Lots of clicky prepared piano. Trombone takes the lead. Still slow, atmospheric.
3- (5:58) Toy-shop clatter, busy but slow. Starkly percussive, not as droney/atmospheric as the other tracks.
4- (8:51) Wailing, conch-shell-like calls from the horns. Gets into some nice group work later, although it can be hard to take the high-pitched squeaky toy/tube that gets played near the end.
