Willie, or Willi as he prefers to be called, is most famous for singing a song called Armagideon Time on the classic reggae riddim called "Real Rock" for reggae uberlabel Studio One. A huge hit in Jamaica and the rest of the world, it was covered by the Clash, and has remained popular, cropping up in films like Ghost Dog. There's a lot more to the man than this one song though. A respected producer as well as an artist, its well worth checking for not only Armagideon Time, but also From Studio One to Drum Street Vol. 1 & 2, Messenger Man and his LPs for the UK dubmaster Jah Shaka.
