Puerto Rico'sPleñaLibre took Pleña and bomba, two rhythms hardly known outside of the barrios of San Juan and New York City, and made them a viable force on the international Latin music scene. The band's musical director, Gary Nuñez, has a broad knowledge of traditional Puerto Rican music and the band plays in a variety of styles. They can rock the house with traditional singing and drumming, then turn around and lay down a smoking, jazz-heavy, Afro-Rican jam. PleñaLibre has earned multiple Grammy nominations and continues to call attention to the rich folkloric traditions of Puerto Rico.
