What instrumental group backed many Stax Records artists?

What instrumental group backed many Stax Records artists? Booker T. & the M.G.’s backed many Stax Records artists and served as the label’s de facto house band.

The Memphis group formed in 1962 with Booker T. Jones on organ, Steve Cropper on guitar, Lewie Steinberg on bass and Al Jackson Jr. on drums. Donald “Duck” Dunn later replaced Steinberg and became the group’s best-known bassist. Their instrumental hit “Green Onions” established them as recording artists in their own right.

At Stax, the musicians supplied the rhythmic foundation for records by Otis Redding, Sam & Dave, Carla Thomas, Albert King, Eddie Floyd and Wilson Pickett, among others. They helped define the earthy, groove-centered sound often called Memphis or Southern soul. The sessions could also include the Memphis Horns and other Stax musicians, so the broader studio ensemble is sometimes confused with Booker T. & the M.G.’s specifically.

The Funk Brothers were Motown’s principal house musicians in Detroit, while the Wrecking Crew was a Los Angeles session collective. The Memphis Horns were a horn section, not the main instrumental rhythm group named in the answer.
