From the days of playing greasy local juke joints to headlining major festivals, JJ Grey remains an unfettered, blissful performer, singing with a blue-collared spirit over the bone-deep grooves of his compositions. His presence before an audience is something startling and immediate, at times a funk rave-up, other times a sort of mass-absolution for the mortal weaknesses that make him and his audience human. When you see JJ Grey and his band Mofro live?and you truly, absolutely must?the man is fearless.
