one of my favourites is this old dude.
one, Mr. Ernest Ranglin. damn near 80 and still riding the riddims. he's credited with helping pioneer Ska, been releasing music since the 60s, did soundtrack work on a James Bond film (Dr. No), worked with Lee Scratch Perry and Jimmy Cliff in the 70s. commercially he seemed to disappear in the 80s before returning in 1996 with the album Below the Bassline, which featured a more jazzy approach to raggae. he also appears on the St. Germain album 'Tourist'.
here's the title track to his return to commercial records from 1996.
if you listen to this and don't feel like the person in the image you should check your pulse because you're probably dead.
