Horse Machine, recorded alongside Underneath Rotting over the summer of 2006, is Pumpkin Buzzard's garage rock album. Featuring live drumming on an extremely minimal set (floor tom, snare, and crash cymbal) and ridiculously unhinged performances on guitar, mandolin, violin, piano, lap harp, synths, and drums, the Buzzard tackles doom metal, strange jamming, punk, noise rock, death metal, dreamy pop, acoustic funk, and more.
