'Variations On A Theme' couldn't be a more appropriate title for this debut from Om. This duo, featuring former Sleep members Al Cisneros and Chris Hakius, carry on right where Sleep left off. Slow, thick waves of distorted bass and complex jazzy drumming flow under chant-style vocals. Although there's no guitar, you don't really miss it, but you can definately here how amazing this band would be with the right guitar player. If you're into Sleep, you need to pick this up.
