Best known as the bass player of Booker T. and the MG's, Donald "Duck" Dunn was one of the guys behind the groove in most Stax/Volt recordings. The Stax sound was known for its heavy bottom end, and Dunn, along with the rest of the MG's (the Stax house band at the time), was responsible for it. After the Stax label gave up the ghost, Dunn went on to a successful career as a producer and session player.
