Arguably, this album kick-started the success that Willie Colón and vocalist Hector Lavoe achieved throughout Latin America. A key to this is the song “Che Che Colé.” The novelty of the arrangement and performances by Willie’s band captured the hearts of music lovers internationally. The blending of African and Puerto Rican rhythms, as well as the innovation and drive that “Che Che Colé” offers, is the result of Willie revamping his style and sound for this album. Cosa Nuestra was unparalleled at the time of its release and rarely duplicated over the following 50 years. The combination of Willie and Hector and the joy they bring to Latin music connoisseurs everywhere is captured in this album for all to enjoy.
