This was
El Gran Combo's first effort for their own label, EGC Records, and the last before the addition of the trombone (which would subsequently be a continuing part of their collective sound). Vocalists
Andy Montañez and
Pellín Rodríguez are still going strong, with selections like bandleader/pianist
Rafael Ithier's compositions of "Sube Nene, Sube" and "Por el Pecho No." A new commercial venture that rated an excellent recording.
