Back in February, we wrote how San Francisco-based Deerhoof had come to the rescue of the stagnant music world with their latest album, Deerhoof vs. Evil (Polyvinyl, January 2011), on which guitarists John Dieterich and Ed Rodriguez, drummer Greg Saunier, and bassist Satomi Matsuzaki do what they do best, taking listeners on a journey through a multitude of crazy sounds, hard-to-decipher lyrics, and offbeat, ever-shifting melodies that delight while they confound. Well, they’re shaking things up again, collaborating with such guests as Physical Forms, Xiu, Xiu, WOOM, the Raccooonists, and Wilco’s Jeff Tweedy and his two sons, inviting them to play over instrumental tracks from the new record and releasing them on 7" vinyl. In addition, they have reissued two earlier albums, 2004’s exciting Milk Man, featuring such killer tracks as “Giga Dance,” “Milking,” “C,” “Desapareceré,” and the title song, and 2007’s Friend Opportunity, with such songs as “The Perfect Me,” all of which have found their way into recent setlists. Deerhoof will be at the Music Hall of Williamsburg on September 20 with Mick Barr and White Suns.
