Mic Flont, Khingz, Paolo Escobar, and the maestro of the track, Spekulation, push it along in a Seattle summertime fashion. “Can’t Wait” is about not being complacent in art and activism, two things that inform each other in the lives of these artists. Catch them all, plus the rising Dex Amora and Jamil Suleman at Columbia City Theater this Thursday (7/30).
