Bob Marley released Redemption Song in late 1980, mere months before his death. It's a powerful song that always struck a chord with me. "Emancipate yourself from mental slavery" is Marley making Marcus Garvey's words immortal.
I love the song, but my go-to version isn't Marley, it's Joe Strummer. Joe Strummer & the Mescaleros recorded Redemption Song just prior to Strummer's death and it was released posthumously. Here it is, if you've never heard it.
