Okay, I’ll admit I haven’t paid much attention to stoner rock group Clutch since the mid-’90s. Clutch released their second, self-titled full-length in ’95, and it was in heavy rotation on my portable CD player in high school. The whole album’s pretty strong, but “Spacegrass” is the sticky stoner masterpiece—and a total earworm. “Dodge Swinger 1973, top down, chassis low/ Panel dim, light drive, Jesus on the dashboard/ T-minus whenever it feels right, Galaxy 500.” My ignorance of Clutch’s post-’90s catalog is no reason to miss what promises to be a nostalgic yet forward-looking concert at Sunshine Theater (120 Central SW) on Thursday, Nov. 7. Austinite metal outfit The Sword and ’70s-meets-’90s punk-rock band American Sharks open. This 13-and-over show revs up at 8pm, and presale tickets are $23.
