Willie Colón, who put his first full-length record out at the early age of 17, is a revered icon of salsa and bolero music, composing and performing throughout his career alongside the likes of Celia Cruz, Soledad Bravo, Rubén Blades, and even David Byrne of the Talking Heads. His numerous collaborations with vocalist Héctor Lavoe are considered some of the greatest works of Latin music of all time, and have rendered a slew of gold and platinum records. Critics tend to agree that one ofhis finest works came in 1970, with the release of Cosa Nuestra. Smooth and brisk tracks like "Ausencia" and the Latin club track "Che Che Colé" were huge hits among New York's barrio youths, bolstered by Lavoe's potent vocal flair, and Colón's slick, trombone-heavy production. It was their first gold-selling record, and served to cement the duo's legacy as Latin music icons.
