Biography
From AllMusic: Sometime in 1966, producer Tom Wilson persuaded (probably with the offer of some quick bucks) Sun Ra and members of his band, and the members of the Blues Project, to lay down 35 minutes of music for a Batman and Robin album credited to "The Sensational Guitars of Dan & Dale." Beyond Sun Ra and his band, there's Danny Kalb, Andy Kulberg, Steve Katz, and Roy Blumenfeld.
