They recruited Pedro Sánchez (vocals/keyboards) and Javier de Juan (drums) to form a quartet.
Their first album, Pensando en tí, was released later that year to critical approval but only modest sales.
Llegas de madrugada and Un día mas, also failed to sell in large quantities.
Ramírez left the group, unhappy with decisions made by their record company, and Pepe Marchante came in as bassist.
The group finally made a commercial breakthrough in 1985 with the album Funkyllac, which contained the hit single "Arturo" and featured harder rhythms which proved popular with record buyers.
