New Orleans has a blues circuit, but it's made up of below-radar neighborhood bars, including Joe's House of Blues, the Young at Heart Lounge and The Place to Be. In conjunction with a radio documentary project by Richard Ziglar and Barry Yeoman of Durham, N.C., there's a free blues show featuring local talent at the Mother-in-Law Lounge at 7 p.m. Friday. Performers include guitarist/vocalist John T. Lewis (pictured), keyboardist Rico Watts (who used to play with Ernie K-Doe), R&B singers Tommy Singleton and C.P. Love, bassist Richard "Tricky Dick" Dixon, saxophonist Lloyd Givens and drummer Ben Sandmel, who's played with the Hackberry Ramblers for years and used to back-up local bluesman Boogie Bill Webb. The Millennium Band also performs.
