Tonight the California rap trio Pac Div swings through Reggie’s Rock Club, and knowing the group’s ties to Chicago hip-hop in general and the Cool Kids specifically, it’s not too much of a gamble to expect some unannounced guest appearances. And New Jersey indie group Delicate Steve plays Subterranean with local post-post-emo rockers Like Pioneers, and the Reader-recommended local psych outfit celebrate the release of their new record at the Empty Bottle with fellow Chicagoans Toupee headlining. Tomorrow evening underground rock royalty Kim Gordon performs alongside local noise artistes White/Light at their ongoing Face the Strange series at the MCA, while local avant-pop mainstays Bobby Conn & Monica Boubou play the Hideout. And Wednesday night local self-described “prog jazz” group Herculaneum plays the Hideout while Rhett Miller and Robbie Fulks offer a rootsier program at City Winery. Hit the jump for two more Soundboard-approved recommendations.
