The music world is in mourning. Amado Jaén, one of the founders and bassist of Los Diablos, has died at the age of 74. The composer died last Tuesday night at the Hospital Clínic in Barcelona, ??due to cancer that he had been suffering from for months and for which he underwent surgery last week.

The composer is behind some of the band’s best-known songs, such as the now legendary Un Rayo de Sol, adapted by the Spaniard from the composition of two French authors.

The musician was also a creator of music for advertising and television spots. Last February, Jaén could be seen in one of his last public events. The composer attended with his bandmates Agustín Ramírez and Enrique Marín to the inauguration of the Los Diablos Park in L’Hospitalet de Llobregat together with the mayor, Núria Marín, and there they premiered their song Som de L’Hospitalet (‘We are from L ‘Hospitalet’), city where the group was born in the 60s.

Jaén was part of Los Diablos from its beginnings, when the duo formed by singer Agustín Ramírez and bassist Enrique Marín became a quartet with Amado on bass and Emilio Sancho on drums.

The group’s first commercial success was precisely Unray de sol, from Jaén, also the author or co-author of other songs that were soon baptized as “summer song”, such as Acalorado, Oh oh July and Fin de Semana, among many others.

He also composed songs for other performers, such as Y solo tú, which Bacchelli sang, and adapted songs from television cartoons such as Inspector Gadget, Lucky Luke, Doraemon or Bola de Drac Z.
