Spanish pop/rock band Nacha Pop was formed in 1978 by ex-Helicopeter Uhu singer/guitarist Nacho Garcia and bassist Carlos Pascow, who were soon joined by Garcia's cousin, singer/songwriter Antonio Vega. That same year, the band recorded a demo featuring "Chica de Ayer" and "Sol del Caribe," signing with Hispavox in 1980; they then issued a self-titled album produced by Teddy Bautista.
