Violinist Daniel Bernard Roumain combines seemingly incompatible musical genres — hip-hop, funk, rock and classical. And who's going to argue that it doesn't work? Roumain has a doctorate in composition from the University of Michigan, and he's collaborated with a wide range of artists, including jazz singer Cassandra Wilson, choreographer Bill T. Jones, minimalist master Philip Glass, the Florida Philharmonic, 2 Live Crew and DJ Spooky, That Subliminal Kid. Roumain, who goes by the stage name DBR and has been dubbed a classical musician for the iPod generation, grew up in the South Florida town of Margate. He gives a workshop at 3:30 p.m. today at Tampa Housing Authority, 1500 N Rome. On Thursday at 8 p.m., his ensemble performs Etudes4violin&electronix at the TECO Theater of Tampa Bay Performing Arts Center. This is a "pay what you can" event. (813) 229-7827; tbpac.org.
