Bitchin Bajas began as a modest side project from Cooper Crain, the guitarist for Krautrock-obsessed experimentalists Cave. They have since expanded into a much-admired cult-favorite drone band where the players focus on basic tonalities and branch out from there. This self-titled "double album" is considered their fifth (though it's cassette-only, and tiny vinyl releases muddy the count). “Field Study” dares to turn ambient nature recordings into digitized flurries of sound, while “Brush” pulses with near-urgency that expands and contracts into a hypnotized state. The almost 19 minutes of “Tilang” allow for even greater rewards. Popol Vuh fans unite!
