Booker T. & the M.G.'s were an iconic American instrumental soul band that emerged from Memphis in the 1960s, becoming one of the most influential and prolific session groups in music history. Led by keyboardist Booker T. Jones, the group—featuring Steve Cropper on guitar, Donald "Duck" Dunn on bass, and Al Jackson Jr. on drums—created the distinctive "Memphis sound" that backed countless Stax Records hits and scored their own chart-topping instrumental classics like "Green Onions." Their tight, groovy arrangements and soulful musicianship made them legends of soul, funk, and R&B, influencing generations of musicians across multiple genres.
