Last month we wrote about the Opportunity Shop, a temporary art and community space in Hyde Park that was supposed to last only through the end of April. It proved so popular, and the donations proved so plentiful, that the Op Shop was extended through the beginning of June. This Saturday night is the Op Shop’s second-to-last party, and they’ve booked a handful of local bands to play: Lakesigns, the Names that Spell, Jesus Crisis, and Squat the Condos. The show starts at 8, with doors opening a half hour before that. A $2 suggested donation will get you in, or a $5 suggested donation will get you admission and “a Dixie cup to fill with whatever you want (there will be fillings),” according to Lakesigns multi-instrumentalist Eric Mayer. And mark your calendars a week from Saturday for the art space’s closing event, the Op Shop Ball.
