Whether you’re new to D.C. and looking for an introduction to what makes this music scene tick, or you’re a regular who’s been in the know for years, there’s no better place to be than U Street Music Hall on Sunday. The evening will weave together D.C.’s musical past and present with Government Issue’s John Stabb as host, and it would be hard to find a better class on the subject. It starts with a screening of Metrozine founder Scott Crawford’s Salad Days, a documentary about the city’s hardcore and DIY scenes during the 1980s, and continues with a who’s who and who’s next of jazz, hip-hop, punk, and go-go. Drew Kid and the Elevators bring a youthful perspective to fusion. After four years, The Cornel West Theory is back with a new album of old school beats that gives political voice to regular people. Loud Boyz (pictured), the area’s latest party-punk heroes, are gaining notoriety quickly. It all culminates with Roc Mikey leading members of UCB and TCB to create a go-go super group. Any one of these performances are worth the price of admission. The performance begins at 5 p.m. at U Street Music Hall, 1115 U St. NW. $15. (202) 588-1889. ustreetmusichall.com.
