With a new sound system and retooled stage, Jasper O’Farrell’s in Sebastopol has become an even stronger addition to the slew of valuable venues in a congested downtown Sebastopol area. Better yet, the Wednesday-night Brainstorm series is bringing in heavy hitters from the world of glitch, grime and dubstep, which, for those who don’t follow electronic music microgenres, is the latest craze out of England defined by bulbous syncopated bass growls and traipsing rhythms. This week, Brainstorm welcomes Christian Bauhofer, aka Minnesota, whose melodic take on the genre transforms classics like “California Dreamin’” into cranium-bending delights. Be there on Wednesday, Jan. 12, at Jasper O’Farrell’s. 6957 Sebastopol Ave., Sebastopol. 9pm. $5. 707.829.2062.
