Chicago space rockers Grimble Grumble will perform at Lo-Fi Sat. Feb. 18 with Black Nite Crash. I’d lost track of GG in the late ’90s and thought they’d gone to that great FX-pedal-laden studio in the sky. But no. They’re back on the live circuit to lull us into a blissful trance state like a Windy City Windy & Carl, all loose, sprawling compositions and languid guitars chiming to infinity. (Note: Space Waves canceled.) More info over here.
