Bob Marley and the Wailers was a Jamaican reggae band led by Bob Marley. It developed from the earlier skavocal group, the Wailers, created by Marley with Peter Tosh and Bunny Wailer in 1963. By late 1963 singers Junior Braithwaite, Beverley Kelso, and Cherry Smith had joined on. By the early 1970s, Marley and Bunny Wailer had learned to play some instruments and brothers Aston "Family Man" Barrett (bass) and Carlton Barrett (drums), had joined the band. After Bunny Wailer and Peter Tosh left the band in 1974, Marley began touring with new band members. His new backing band included the Barrett brothers, Junior Marvin and Al Anderson on lead guitar, Tyrone Downie and Earl "Wya" Lindo on keyboards, and Alvin "Seeco" Patterson on percussion. The "I Threes", consisting of Judy Mowatt, Marcia Griffiths, and Marley's wife, Rita, provided backing vocals.
