In 1970, Eddie Palmieri released Superimposition, an LP with descargas such as "Chocolate Ice Cream" and "17.1", which featured Alfredo "Chocolate" Armenteros on trumpet. Armenteros would later join Grupo Folklrico y Experimental Nuevayorquino, an ensemble founded by musicologist and producer Ren Lpez. The group played extended descargas with a modern salsa sound.[22]
