Black Uhuru around a long time. Many artists I'd name have been listed already... excuse any duplicates:

Lady Saw, Tanya Stephens, Dennis Brown, Freddy McGregor, Tami Chynn, Da'Ville, Jah Cure, Luciano, Elephant Man (in Negril tomorrow night), Sean Paul (new CD out the last week or so), Sanchez, Shaggy, Voicemail, Wayne Wonder, Wayne Marshall.

So much reggae, so little time :-)
