FRIDAY: >> Two shows for DAM! Fest tonight, with events at Rock and Roll Hotel and the Red and the Black. The former includes an appearance by recent Three Stars subject the Beanstalk Library, plus The Exit, Dragons of Zynth and The Teeth. Stick around for the free afterparty, We Fought the Hej, a combo of two of our favorite DJ nights, Hej Hej and We Fought the Big One. >> Don’t forget to check…

Saturday at the Rock and Roll Hotel. Dr. Dog with The Teeth and Hoots and Hellmouth. $12. Doors at 8:30, Music at 9:30. Depending on the circles you run in, Dr. Dog are either busy working a tired formula of lo-fi and late-period Beatles nostalgia or are one of a host of Philly groups artfully resurrecting the heady psych-pop era of the late 60s and early 70s. Both camps need to do themselves a favor…

FRIDAY: >>Do you like Hall and Oates and Haddaway? Who doesn’t? The Black Cat is hosting Crap, a dance night of bad music on purpose. We advise loosening your Macarena muscles and preparing your ears for “singers” like Don Johnson, Eddie Murphy, and Bruce Willis. 10 pm, free. SATURDAY: >>There are more art openings than we can shake a sculpture at today, so check out our Arts Agenda for a rundown. >>Anything called “Underwear Party”…
