Not unlike his fellow musician 50 Cent, voodoo boogie pianist Dr. John was also shot. But the psychedelia doesn’t end there, for the New Orleans native Dr. John replaced his own moniker, Mac Rebennack, with that of a voodoo practitioner when he was coming up in the early R&B scene as a guitarist (until he caught a bullet in the hand and switched to piano). Then it was onward and outward, recording solo and group sessions with Eric Clapton, The Meters and John Hammond Jr., a Popeyes Chicken jingle or two, and playing live shows that were one continuous Mardi Gras. Lately he’s been throwing his begumboed drawl into hurricane relief efforts, and like many who fled the storms, he’s found his way here, where he’ll play Lewis Ginter’s Groovin’ series Friday, Oct. 6, at 5:30 p.m. Tickets are $20-$25. 262-9887.
