Fri. Why stay home and watch VH1 when you can love the '80s live as the "You & I Reunion Tour" rolls into DAR Constitution Hall (202-397-7328) with headliners Teena Marie and Rick James. Both created classics, from her "Square Biz" to his "Super Freak" and "Give It to Me, Baby" to their "Fire and Desire." The show gets even better when you add Morris Day & the Time, a group that had a few classics of its own ("777-9311," "Jungle Love"). . . . Cecilia got its start in the Washington area before moving to New York. It was always a favorite of Eric Brace's, who used to write this feature, in part because of the group's pure pop harmonies. Cecilia comes home for an evening at Jammin' Java (703-255-1566).

Sat. Senatobia is playing its pop-rock at Galaxy Hut (703-525-8646). The Asheville, N.C., group has gotten decent airplay on college radio for its guitar-based sound. . . . Make a day of it by heading out to Sperryville for the Rivers and Roots Music Festival. Starting at noon, there are a variety of performers lined up, including Eric Freeman, Tinsmith and Paul Reisler. Headlining with a show about 7 p.m. is the pop-folk duo the Kennedys. For additional info, visit www.riversandroots.com. . . . DJ Rap shows off her spinning skills at Dream (202-636-9030). . . . Those who watch TV's "Queer as Folk" know the dance club on the series is called Babylon. Last year, to promote the soundtrack, the Babylon set went on the road. This year it's back, only it's "Future Babylon," re-creating the club as it might be in 2050. Join the sweaty party at Velvet at Nation (202-554-1500) with DJs Manny Lehman, Tracy Young and Peter Rauhofer. . . . The quirky They Might Be Giants performs its clever pop in a free show at the Maryland Science Center (410-685-5225).

Tues. David Byrne starts a three-night run at the Birchmere (703-549-7500). For details on what the artful Mr. Byrne is up to, see the Spotlight on Page 14. . . . The Greencards captured the Best New Band award at the 2004 Austin Music Awards for the group's skillful playing of contemporary bluegrass and Americana. Find out why at IOTA (703-522-8340), where they're on a bill with another fine Austin group, the Onion Creek Crawdaddies, who play what they call "beergrass music." And they play it well, I might add. . . . The indie-pop of Beulah comes to the Black Cat (202-667-7960). The band has a confident sound with a nice appreciation for melody.

Weds. 4 Way Street plays pop-folk Americana. That's a broad label because the group, featuring four veterans of the Philadelphia music scene, has a broad approach -- one that comes together nicely. They join pop songsmith Glenn Tilbrook, who was one-half of the clever Squeeze, at the Rams Head Tavern (410-268-5111) in Annapolis. Tilbrook is also at IOTA on Thursday (703-522-8340) . . . Bluegrass heavyweights abound at Wolf Trap (703-218-6500) when the "Great High Mountain" tour shows up. Alison Krauss & Union Station, Ralph Stanley, the Whites, Norman & Nancy Blake and several others are part of the tour performing music from "O Brother, Where Art Thou?" and "Cold Mountain."
