Gregory Porter won over our critic at his Cistern concert last night. Joy Vandervort-Cobb wrote, "Although Porter has the capacity to riff and scat and holler with the best of them, he is a straight-ahead jazz singer, emotionally and rhythmically connected to the tunes he sings, even as he demonstrates he has the capacity to make the music leap forth." He's got one more show at Spoleto on Saturday night. Check out our video from his sound check for a hint of what's in store. And here's our interview with Porter if you feel like doing a little background reading before the show.
