Marquise Knox, 2 p.m.

Marquise Knox is a young blues artist who comes out of the St. Louis area. The guitar is his instrument of choice on which he says he can best express himself. Marquise also plays the harmonica and of course sings - very well, I might add. I had the pleasure of seeing him perform this year in St. Louis on our return trip from the International Blues Challenge in Memphis. I was pleasantly surprised to see the poise this young man has and the stage presence of someone many years older.

Singer, songwriter, and slide-guitarist Roy Rogers is not a blues purist. He could write a song in the style of Robert Johnson - the reason he became a blues player in the first place - but what would be the point of that?

"I'm just trying to stretch it," he said in a recent phone interview.

So on his new recording Split Decision - his first studio album with his Delta Rhythm Kings trio in seven years - there's the instrumental "Your Sweet Embrace," with a flamenco section by Ottmar Liebert, and "Rite of Passage" has a warm, funky jazz groove before taking a guitar-solo detour into the blues. "Bitter Rain" deals with Hurricane Katrina and has what Rogers called "almost kind of a tempest riff," and closing instrumental "Walkin' the Levee" features sax and a guitar tone simultaneously fuzzy and razor sharp. "River of Tears" is an irresistibly upbeat pop number despite its theme of sadness.

James Brown was known as the Godfather of Soul, but his other nickname was "the hardest-working man in show business." Sugar Pie DeSanto is known as the female James Brown because of the way she works a stage, even at 73.

"What an honor, you know, to be the lady James Brown," Sugar Pie said in a recent phone interview. "Because I was cuttin' up and I still cut up - if you know what I mean. I was getting down, all right? And with God's help I will still be getting down 'til I don't want to sing anymore. Wait 'til I'm 85 and they push me on-stage in a wheelchair - 'And here she is!' - and I bet I'll be mastering that wheelchair, having it spinning and everything!"

Blues guitarist, singer, and songwriter Fiona Boyes hasn't always been a blues musician. In our recent interview, Boyes laughed as she remembered her early musical experiences with a different instrument: the clarinet. "It was kind of ... a nerdy instrument," she said. "Maybe if I'd been given a bit of New Orleans jazz or something, I would've stuck with that instrument."
