Fri. Maybe starting out in San Francisco, where outrageousness is routine, influenced their approach, but the Tubes don't just put on a show when they perform, they create a spectacle. The pop-rock group is at Jaxx (703-569-5940) in full regalia. The group will be at the Rams Head Tavern (410-268-5111) on Saturday. . . . Harmonica master Frederic Yonnet is at the IMAX Jazz Cafe (202-633-7400) at the National Museum of Natural History with his blend of jazz, blues, funk and African rhythms. . . . Q and Not U, Decahedron and Mary Timony form a rocking lineup at the Black Cat (202-667-7960).

Sat. More rock takes place at the Warehouse Next Door (202-783-3933) as it hosts D.C. Rock City. It's a mini-festival celebrating the city's hard-rock scene. The event features local bands, a DJ spinning rock and metal, and displays of related photography and poster art. . . . And while we're on the topic, few bands ever rocked harder than Mission of Burma in its heyday. Find out more about the group in the Spotlight on Page 8 and hear them at the 9:30 club (202-393-0930).

Sun. The one and only David Bowie is at the Patriot Center (202-397-7328). Do I need to say more? . . . It's a reggae party at the Show Place Arena in Upper Marlboro thanks to performances by Beres Hammond, Maxi Priest and others. (Call 301-422-1728 for info.). . . KRS-One isn't called "The Teacher" for nothing. His rap has long been socially conscious while maintaining its hard-core edge. Listen and learn at the 9:30 club (202-393-0930). Also on the bill is the underrated Big Daddy Kane, the man responsible for such gems as "I Get the Job Done" and "Big Daddy vs. Dolemite," and Speech from Arrested Development. . . . Breaking Laces plays indie rock that might at times remind you of Weezer. The group is at Galaxy Hut (703-525-8646).

Weds. Mark Erelli has gotten good critical buzz about his songwriting. He lacks consistency (being overly earnest is an occasional flaw), but when he's good the praise is justified. Erelli is at Baldwin's Station (410-795-1041). Or catch him at IOTA (703-522-8340) on Thursday. . . . Taj Mahal, the bluesman with a world music beat, performs for the first of two nights at the Birchmere (703-549-7500). He also will play at the Rams Head Tavern on May 22 and 23.

Thurs. The Supersuckers are at the Ottobar (410-662-0069) in Baltimore. The group is doing one country set and one rock set. If you've heard them before, you know they can be a lot of fun.
