The Canadian folk and alt-rock singer is known for his progressive messages for social justice, the environment, politics, and welcoming spirituality, as much as he is for the sheer volume of material put out over 40 years. With over 300 songs recorded for 30 album releases, this hard-working rocker has seen 20 of these records achieve platinum status. With his 2014 autobiography, Rumours of Glory: A Memoir praised for its eloquence and humanity, Cockburn represents the best of the Canadian spirit.
