Examples of the mass appeal in the program: Freddy Fender (a leading tejano music artist who anglified himself) Los Lobos (who went English language initially before returning to their roots) Richie Valens (who composed/penned/performed la Bamba) and of course the superstars Carlos Santana , Gloria Estefan, Shakira, Ricky Martin etc.
Examples of keeping it real and trying to and in some cases finding a wider audience: Dizzie Gillespie (really the inventor of what is called latin jazz today), Fania All Stars (the whole lot of them, huge amount of footage with Hector Lavoe, Willie Colon, Johnny Pacheco, Cheo Feliciano) and more recently the reggaeton artists Daddy Yankee and especially Tego Calderon.
