You have plans for Saturday night now. If you had any already, you have new ones now. Richmond-based Cloak/Dagger will be shredding and thrashing and tearing up the Black Cat’s backstage when they open for Texas bands Bad Sports and headlining Radioactivity. It’s gonna be a hell of night for punk fans with these three fantastic acts. Cloak/Dagger burst right into furious, pounding guitars and roaring, raspy vocals that’ll surely have the crowd headbanging along. They haven’t put out an album in quite some time, it seems, but some signs suggest they’ll be putting out new material for the masses soon. Give them a listen and catch what’s bound to be a frenzy of punk rock this weekend. Doors at 7:30, $12. -Jonathan Goodwin
