Bob Marley was bigger than pop music. The legendary Jamaican singer-songwriter blended music with spirituality, humanitarianism and politics to leave an imprint that survived his death on May 11, 1981. Although he was only 36, his legacy is durable. An exhibition celebrating the artist who put reggae on the international music map opened Friday at Themuseum. It continues in downtown Kitchener through to Sept. 2. One Love: A Bob Marley Exhibition features 40 photographs and 70 objects, in addition to video, documentary film and interactive installations, which chronicle Marley’s life, times and music.
