In the late 1980s he made his debut as a leader of his own quintet including pianist Jacky Terrasson at International Barbados/Caribbean Jazz Festival.

Described as a cross between the Teddy Pendergrass and Kenny G, Tappin has been referred to as: "the smoothest, saxiest [sic] horn man the Caribbean has to offer.

[9] Tappin has played and recorded with many artists including Luther Vandross, Eddy Grant, Red Rodney, Milt Hilton, Monty Alexander, Ernest Ranglin, Jacky Terrasson, Courtney Pine, Al Harewood, Roy Haynes, Ellis Marsalis, Oliver Jones, Doc Cheatham, Pete King, Mutabaruka, The Wailers Band, Earl Brooks Jr.,[10] Frederick "Toots" Hibbert, Third World, Mikey Bennet, Dennis Bovell, Sandra Cross, Luther François, Maxi Priest, Bongo Herman and Dean Fraser.

Tappin attributes much of his success to a former tutor at Berklee College of Music, Bill Pierce (Art Blakey and the Jazz Messengers), uncle Elombe Mottley, and his parents for their constant love and support.
