Radian + Sawyer/Yeh/Wooley Trio + Koen Holtkamp

Don't miss out on the sonic fascination that Austrian trio Radian brings to bear, most recently on its unusually grainy, gritty album, Chimeric. The band's U.S. trips are infrequent—catch this arty bill or risk waiting a couple of years. Opening are noise-improv pros Ryan Sawyer, C. Spencer Yeh and Nate Wooley, as well as local experimental electronica luminary Koen Holtkamp.
