In 1974, Pacheco replaced El Conde (who went on a successful solo career) with Héctor Casanova and renamed his band Pacheco y su Tumbao Añejo ("Pacheco and his old tumbao", as opposed to his previous band "the new tumbao"). They released El maestro in 1975 and El artista in 1977. However, Pacheco's focus during the 1970s, apart from the All-Stars, was a series of collaborative albums between members of the label, including himself. He collaborated with Celia Cruz, Justo Betancourt, Papo Lucca, Pupi Legarreta, Luis "Melón" Silva, Celio González and José Fajardo, among others. With Héctor Casanova he released another album, Los amigos, in 1979. After his various reunion albums with El Conde, including the Nuevo Tumbao 25th anniversary album Celebration, Pacheco released ¡Sima! in 1993, his last studio album.
