The influence of hit records from the USA and the UK in the early 60s had resulted in a musical style the French called yé-yé. Spain also adopted the term to describe this new type of beat-oriented pop, while maintaining its own musical identity via sexy rhythms and an underlying current of drama and flamenco, as evidenced in this predominantly up tempo all-female compilation. The aptly named Hispavox was considered the most important Spanish record label, mainly because they had a talented team of producers, arrangers and studio musicians who between them created the "Torrelaguna sound". Furthermore, they had Karina, who was known as the queen of Spanish yé-yé with her angelic looks and voice.
Zafiro entered the market with a series of girl singers, including the dynamic Marisol, a child actress turned pop singer who spent much of the 60s on the silver screen.
