Tyrone Cotton is often called a blues singer. And there’s a certain amount of truth to that, I suppose. His songs sometimes tell stories about places where you might expect to find a dimly lit motel room or a jealous man ready with rage, or both. And his guitar brings to mind the loping rhythmic grind of the real honest-to-God blues of the Delta, the kind of gentle sweep that makes you feel like you’re falling forward, very slowly, into a warm, calm pool. Yes, Tyrone Cotton can hypnotize you, just the way the great blues masters did.
