Peter Tosh

Watching a stranger play one song for half a day, Tosh memorised every movement of the man's fingers, then performed it straight back. That self-taught ear turned him into the Wailers' original guitarist and keyboardist, the musician his bandmates learned from.

With Bob Marley and Bunny Wailer, he slowed the group from ska to rocksteady, then cut early reggae with Lee "Scratch" Perry. He co-wrote 'Get Up, Stand Up' but quit in 1974 when Island boss Chris Blackwell refused to issue his solo album.

Afterwards he made militant, Rastafari-rooted music: the title track of Legalize It became a cannabis anthem, and Bush Doctor featured a duet with Mick Jagger. At the 1978 One Love Peace Concert he lit a spliff onstage and berated Jamaica's political leaders. No Nuclear War, his final record, won a Grammy in 1987, the year he was shot dead during a robbery at home.
