I definitely like most the Bob Marley recordings on the Island Label (Tuff Gong has vinyl with a strange texture), with Uprising being my favorite.
I love live reggae and here are a few of my favorite recordings that capture the energy of the performance.
Live at Reggae Sunsplash - Yellowman
Live at Reggae Sunsplash: Since I Throw the Comb Away - Twinkle Brothers
In Concert: The Best of Jimmy Cliff (Live)
Live - Toots & The Maytals
I have seen may reggae concerts in my life, and I would have to say that Toots and the Maytals put on the best show. I always wanted to see Third World, but when I finally saw them it was a disappointment. Steel Pulse is decent, but Toots blows them off the stage. The Gladiators, Mutabaruka, and Eek a Mouse are also excellent live performers.
