I realized the OP asked to find stuff other than Bob Marley, but have you listened to some of his earlier stuff that gets very little play?
The old recordings of songs like Soul Rebel, Duppy Conqueror, and Fussing and Fighting give you an idea of where his music came from and how electric he was back in the days. Typically the sound quality is poor, but well worthwhile IMO.
"There She Goes" may be the greatest pop song ever written and his performance is just breathtaking for such a light little song. He puts out all the grief and tragedy of a broken heart, while keeping it light and lively, almost giving you a wink on the side.. Just a great, great, underappreciated song.
