The album is particularly noteworthy for the early appearance of guitarist
Duane Allman, later founder of
The Allman Brothers Band, who made some of his first recordings as a
sideman on the album.[2] His guitar work on the title track is credited as what first drew
Eric Clapton to him, who two years later invited Allman to join him as part of
Derek and the Dominos.[3] Allman's performance on the album also compelled
Atlantic Records executive
Jerry Wexler to buy out his recording contract and use him in further Atlantic recording sessions, beginning his prolific career as a
session musician. Pickett is also backed by members of the
Muscle Shoals Rhythm Section on the album. Rhythm Section member
Jimmy Johnson later credited Allman's performance on this album as the beginning of
Southern Rock.[4][5]
