Mercury teamed Campbell up with the then unknown producer Lou Reizner, who used Mike Bloomfield and The Paul Butterfield Blues Band, who had previously backed Bob Dylan, to ensure the style was very similar to Dylan's sound. Artists appearing on the album include Mike Bloomfield (guitar), Paul Butterfield (harmonica), Sam Lay (drums), Mark Naftalin (organ) and Peter Cetera (bass).
