If you have a taste for unpredictable music yet aren’t brave enough to face this past week’s clarion call for a brutal Chicago winter, let WHPK’s Pure Hype challenge your ears while your body sits comfortably in your favorite armchair. This Friday at nine, California’s seasoned multi-instrumental experimental improviser Gino Robair brings his bag of squeals, creeks, and drones for an in-studio performance, supported by Andrew Royal on violin and Aaron Zartzutzki on electronics. If you do feel like venturing out, the Trio WAZ’s show Saturday at the Velvet Lounge should provide more surprises, as it pairs three respected Chicago musicians from disparate corners of jazz. Sax and clarinet player Edward Wilkerson has deep ties to the tradition of Chicago jazz as the former president of the AACM, while WAZ band mate Tatsu Aoki, on double bass, simultaneously investigates American jazz and traditional Asian music. Free improv master Michael Zerang, however, is known for his abstract use of the drum, which does away with nearly everything but the physical instrument itself. When it comes to rock, check out Alabama’s glammy goth punks Wizzard Sleeve, performing at the Mortville loft in Pilsen.

This Saturday, monochrome Canadian noisemaker the dead are those who have died headlines at the Mortville loft, and he’s bringing festive but equally abrasive pal Ptarmigan. Both share two major influences—the hoary-but-revered members of the noise canon like Boredoms, DNA, and the Dead C, and the young, fresh, and New York Times-approved acts like AIDS Wolf, Hair Police, and Black Dice. The weirdest bearded members of the noise-connoisseur message board chondriticsound.com aren’t fans, but I hear the kids like it. Also on the all-noise bill: Chicagoans piss piss piss moan moan moan.
