It's a great week for blues, but there's lots more happening: Baltimore's FaTKiD (yep, that's how it's spelled) has caught my ear with its poppy punk and is returning to town Friday with a show at the Velvet Lounge (202/462-3213). Friday at Montgomery College's Performing Arts Center (301/279-5301), it's a bluegrass supergroup of sorts, Longview, fronted by Seldom Scenester and Johnson Mountain Boy Dudley Connell and superb singer James King.

Friday at Lewie's (301/652-1600) and also Saturday at the State Theatre (703/237-0300) and Sunday at the Ram's Head (410/268-4545) it's the January All-Stars featuring Catfish Hodge, Tom Principato, Brian Auger, Ron Holloway, Steve Wolf and Pete Ragusa. And Friday at Jaxx (703/569-5940) it's blues/rock/country pianist and songwriter Leon Russell. Both Friday and Sunday at IOTA (703/522-8340), it's the return of the D.C./Austin/New Orleans musical amalgamation,including Derek Huston, Jeff Sarli, Scott McKnight, Chris Watling, Jake Flack, Jay Jenc, Alan MacEwan, Jack O'Dell, Tom Corradino and many others.

One of the best rock bands in town, Mother May I, releases its long-awaited new CD at its Saturday show at Iota (with Peter Hayes and Lee Wilhoit). Also, Saturday, Charlottesville acoustic songwriter Terri Allard inaugurates a new venue for the Medium Rare Cafe Concert Series folks (with Carey Colvin), in the Bull Run Unitarian Fellowship Hall (703/924-8992). Songwriter Curtis Hunter makes a postmodern costumed extravaganza out of every performance, and he plays Saturday at the Galaxy Hut (703/525-8646).

Sunday, Big Bill Morganfield, son of blues great Muddy Waters, comes to Paddy Mac's (301/608-3360) to show that the apple doesn't fall far from the tree. Arizona's Giant Sand has been one of the most interesting rock bands for nearly two decades, and they play Sunday at the Black Cat (202-667-7960) (with 5ive Style and the Sorts). A true legend in American music, Doc Watson will perform his folk/country/blues music on Monday at Birchmere (703/549-7500). Also on Monday, local Piedmont blues heroes Cephas & Wiggins (whose 1999 CD was one of my favorites) performs at the Institute of Musical Traditions' concert (301/263-0600).

Also Monday, it's political comedian (and former Capitol Step) Dave Werner at the Improv (202/296-7008). More fine blues Wednesday at the Barns of Wolf Trap (703/938-2404), when two youngsters, Corey Harris and Toshi Reagon take the stage. Local jazz singer Sunny Sumter is a singular talent and you should hear her sing Wednesday at the French Embassy's Maison Francaise (202/944-6091).
