In October 1962, Los Mustang recorded their debut album on EMI-Odeon, featuring cover versions of popular songs like "Quinientas Millas", Peter, Paul and Mary's "500 Miles", Johnny Hallyday's "Madison Twist", and Spanish songs "He de saber" and "No lo ves".
They released the critically acclaimed Reino Prohibido Del Himalaya (meaning Himalayan Forbidden Kingdom) in 2 parts, in line with the psychedelic trend.
It consisted of conceptual songs about earlier advanced civilizations, based on the theories of Hanns Hörbiger and Michel Peissel.
During the 1980s, they experienced a revival with the recording of a new album which once again included versions of oldies and had various performances with arch-rivals Los Sírex.
In 2000, they released a special album to celebrate 40 years of the band, collaborating with artists Luis Eduardo Aute, Dyango, El Dúo Dinámico, Cliff Richard and Jimmy Fontana.
