Good for Cows' fourth full-length, AUDUMLA, finds the formerly acoustic, instrumental 'crust jazz' bass and drums duo starting afresh. Constraints of flying with an upright bass, increasing volumes, and a steady listening diet of Black Metal and Harsh Noise music have lead Ches Smith (Xiu Xiu, Secret Chiefs 3, Marc Ribot's Ceramic Dog) and Devin Hoff (Nels Cline Singers, Xiu Xiu) to reinvent their sound with electric bass, large drums, and electronics.

They use their extensive backgrounds in improvised music for sonic experimentation in the service of the songs, resulting in a compact record with no filler. The Ornette Coleman influence remains, but now is filtered through a lens of early Mayhem, Prurient, Abruptum and Darkthrone. Nine noisy instrumental jams, from dirgey to blasting -- but all heavy.
