Marley, Bob, 1945-81, Jamaican reggae singer, songwriter, and guitarist. As a member of the Wailers, a reggae band that included Bunny Wailer and Peter Tosh, and later on his own, Marley propelled reggae to worldwide popularity. His commitment to nonviolence and the Rastafarian religion are transparent in his music, and his smoky tenor and loping reggae beat combine to enhance the appeal of his political message.
