Yo Mama's Big Fat Booty Band

Friday and Saturday

Yo Mama's Big Fat Booty Band

The Onion selected the Booty Band among its 2007 worst-named groups of the year. If Onion staffers had been listening to the group, they would've been too busy dancing to put fingers to keyboards. In other words, the band's horn-funk mix is superior to nationally renowned sarcasm. Well, maybe not, but the band is still hot.

Details: 9 p.m. Friday and Saturday. 202 Market, 202 Market Square, downtown Roanoke. $10. 343-6644. 202market.net, bootyband.com.

Saturday

Nicole Hart & The NRG Band

Blue 5 is not letting up on you music lovers. It's one fine band after another on the venue's live music lineup. Hart is, er, kinda gorgeous, and she has a big voice, too, with a road-tested backup band that delivers nicely on the band's CD, "Nicole Hart & The NRG Band Live!"

Tonight

Free! Jason Ring at Emerging Artists Series

Ring is the kind of guitarist who makes fledgling finger pickers angry. He's just too good, too fast, too crisp. How can the rest of us pull off that mess of blues? He's part of an Emerging Artists double bill that features the photography of Cricket Powell.
