The late 1960s also saw white youth joining a counterculture heavily associated with political activism, while black youth formed radical organizations like the Black Panthers. Inspired by these movements, Latinos in New York formed the Young Lords, rejected assimilation and "made the barrio a cauldron of militant assertiveness and artistic creativity". The musical aspect of this social change was based on the Cuban son, which had long been the favored musical form for urbanites in both Puerto Rico and New York. The Manhattan-based recording company Fania Records introduced many of the first-generation salsa singers and musicians to the world. Founded by Dominican flautist and band-leader Johnny Pacheco and impresario Jerry Masucci, Fania was launched with Willie Colón and Héctor Lavoe's "El Malo" in 1967. This was followed by a series of updated son montuno and plena tunes that evolved into modern salsa by 1973. Pacheco put together a team that included percussionist Louie Ramirez, bassist Bobby Valentín and arranger Larry Harlow. The Fania team released a string of successful singles, mostly "son" and "plena", performing live after forming the Fania All-Stars
