El Gran Combo de Puerto Rico, commonly known as El Gran Combo, is a Puerto Rican Salsa music orchestra based in San Juan, Puerto Rico. Currently (2012) celebrating its 50th anniversary, it is Puerto Rico's most successful musical group, and is considered "the most popular Salsa group that has ever existed". The group received the moniker La Universidad de la Salsa (The University of Salsa) in Colombia, due to the sheer number of famous salsa musicians and singers who developed their careers with it, who started with the group (particularly Andy Montañez), or who were occasionally backed up by the band (including Celia Cruz, Héctor Lavoe and La India).
