Throughout the 1960s, pianist Eddie Palmieri played an important role in the development of salsa with his conjunto La Perfecta. La Perfecta was one of the first Latin ensembles to feature multiple trombones, one of salsa's distinctive characteristics. The band's repertoire was inspired by Cuban and Puerto Rican dance-oriented styles such as guaracha, son, pachanga and bomba. In 1968, Palmieri disbanded La Perfecta in order to seek a more experimental approach incorporating funk and soul elements into his music. Palmieri and his new ensemble (still similar to La Perfecta, with Barry Rogers being replaced by Lewis Kahn) recorded a series of four albums for Tico that have been said to contain his "best sounding" work. These four albums were Champagne (1968), Justicia (1969), Superimposition
