Duane & Greg Allman is an album credited to Duane and Gregg Allman, originally released by Bold Records in May 1972. The release is essentially an album-length demo recording of the '31st of February', a Tallahassee-based folk rock band featuring drummer Butch Trucks, bassist David Brown, and guitarist Scott Boyer. The '31st of February' formed in 1965 and released their first, self-titled album in 1968. This second recording, according to Trucks, was intended to be their second album. It features Duane Allman on guitar and Gregg Allman on vocals. The two had been performing with the 31st of February for several months.
It was recorded at TK Studios in the Miami suburb of Hialeah, Florida in September 1968. Steve Alaimo engineered the sessions and later claimed producer's credit. The album is notable for the first recording of "Melissa", which was later re-recorded with the Allman Brothers Band.
