His friend Fahey was to be instrumental in the formation of Canned Heat. He had introduced Al Wilson, whom he knew from Boston, to Henry and Bob and Richard Hite. Wilson, Vestine and the Hite brothers formed a jug band that rehearsed at Don Brown’s Jazz Man record Shop. Bob Hite and Alan Wilson started Canned Heat with Kenny Edwards as a second guitarist, but Henry was asked to join. The first notable appearance of the band was the following year when they played at the Monterey Pop Festival. Shortly after Canned Heat’s first album was released, Henry burst into musical prominence as a guitarist who stretched the idiom of the blues with long solos that moved beyond the conventional genres. He had his own style and a trademark piercing treble guitar sound.
