Marc Black and Warren Bernhardt are a pair of music veterans from Woodstock. Marc is a socially-conscious singer-songwriter, while Warren is a world-class jazz pianist, who's played with everyone from Paul Winter to Paul Simon. They share a passion for Tim Hardin: Warren was a member of his band, and Marc lives in his old house. That inspired them to collaborate on a CD, Champions of Love, which includes a couple of Hardin tunes, some blues, and some originals. They treated us to a taste of all three in Studio A.
