As the house band at Stax Records in Memphis, Tennessee, Booker T. & the MG’s may have been the single greatest factor in the lasting value of that label’s soul music, not to mention Southern soul as a whole. Their tight, impeccable grooves could be heard on classic hits by Otis Redding, Wilson Pickett, Carla Thomas, Albert King, and Sam & Dave, and for that reason alone, they would deserve their subsequent induction into the Rock & Roll Hall of Fame. But in addition to their formidable skills as a house band, on their own they were one of the top instrumental outfits of the rock era, cutting classics like “Green Onions,” “Time Is Tight,” and “Hang ’em High.”
