The album was recorded and mixed January 1-4, 2007 by Tim Green at Louder Studios in San Francisco and mastered by Paul Gold at Salt Mastering in Brooklyn. The album artwork was designed by Andy Kman, with illustrations by bassist Mike Eginton.

The album was well-received by critics. Thom Jurek of Allmusic gave it 4½ stars out of 5, saying that They literally enter the sonic maelstrom of inspiration and free flowing, molten, deeply emotional energy where most felt it was at its peak, and they go up from there. Drawing comparisons to American and British psychedelic acts of the 1960s and 1970s such as Jimi Hendrix, Cream, Free, and Humble Pie, as well as more recent Japanese acts such as The Stars and Acid Mothers Temple, he remarked that "they're a whole other thing in American power rock right now. They point a way that few will be able to follow. George Crosland of Skateboard Revolution called the album A mix of Motörhead, the Melvins, Funkadelic and Led Zeppelin, kind of; music to get amped and stay amped to.
