In September 1972 El Gran Combo released the album Por El Libro. It was Rodríguez last studio recording with the group. During rehearsals for their upcoming record, En Acción, the leader of El Gran Combo, Rafael Ithier found out that Rodríguez had signed a contract with Borinquen Records. Rodríguez told Ithier that he was going to record an album of Boleros and that he was going to continue singing Guarachas with El Gran Combo. Ithier felt that was not a good idea and was not willing to take that risk of having Rodríguez as a member of the band and as a solo artist at the same time. Ithier suggested that Rodríguez should leave the band and Roríguez left to pursue a solo career.
