Two Hall of Fame bluesmen on one stage – and that’s just the start of what’s in store when Elvin Bishop and Charlie Musselwhite join forces. Between them, there are more than 100 years of the blues, and this promises to be a front-porch session that shimmers with history and that rarest musical quality: authenticity. Bishop, with his Gibson guitar, and Musselwhite, with his wailing harmonica, show us the roots of Chicago blues in this meeting of musical minds.
