A jazz guy plays with a heavy rock band? That would be the superficial description of Sco-Mule. A deeper examination shows that John Scofield and Gov’t Mule’s Warren Haynes are twin brothers of different mothers. Each possesses a yearning, restless soul, constantly seeking new musical forms and combinations. Each is fearless behind his guitar. And each is possessed of a virtuoso talent and, seemingly, can do whatever he wants.
