"My passion for the group grows every time I'm with them," says Joe Bello of D.C.'s Different Drummers. Bello is not the only one. Tonight the group's director heads up a gala concert celebrating the organization's three decades of making music. That's 30 years of passion. Roby Chavez of Fox 5 News will serve as guest emcee at the concert, a kickoff to the new season, and it will showcase all ensembles in the group: the DCDD Marching Band, DC Swing!, Capitol Pride Winds and the Capitol Pride Symphonic Band. The concert will close with "On Wisconsin," which may be best known as the Badger State's official song, but it was also the very first march ever played by DCDD. Talk about an encore. Saturday, Nov. 6, at 7:30 p.m., Bell Multicultural High School's CHEC Auditorium, 3101 16th St. NW. Tickets are $20. Visit dcdd.org.
