Gary, that's Derek Trucks, formerly of the Allman Brothers. His wife is Susan Tedeschi, and that's their band. In my view, one of the great guitarists, and great touring bands, around today. Their lineup includes 12 musicians on stage, plus frequent guests. Their new material is quite good, plus they play lots of older material from the Dead, Allman Brothers, Derek & The Dominoes, Mad Dogs & Englishmen, etc. Absolutely wonderful band.
