A sprawling monster of an album, Oneida's Each One Teach One is a double-disc set that is equal parts compelling and difficult. The first disc comprises two extended fifteen-minute tracks, each one based on a single pummeling riff that is repeated ad nauseum with tiny variations. These songs will leave some banging their heads and most others wanting to bang their head against a wall. The very idea seems unpleasant, but somehow Oneida pulls it off, beating the shit out of the groove and making the most of dense, subtly shifting textures. There's not a single second that isn't filled with melting organ drones, fuzzed-out guitar, or overwhelming electronics.

The second disc is much more accessible. It's song lengths are conventional, but the stoner-psych-rock freak-out continues, with nods to Krautrock experimentalism: tape loops, backward recording and more.

Thankfully, the members of Oneida aren't content to mine these genres in a purely derivative manner like most of their peers are. There's real experimentalism at work here, and it makes for an interesting, if uneven, listen.
