Luis Alberto Spinetta (23 January 1950 – 8 February 2012), nicknamed "El Flaco" (Spanish for "skinny"), was an Argentine singer, guitarist, composer and poet. One of the most influential rock musicians of Argentina, he is regarded as one of the founders of Argentine rock, considered the first incarnation of Spanish-language rock. Born in Buenos Aires in the residential neighbourhood of Belgrano, he was the founder of iconic rock bands including Almendra, Pescado Rabioso, Invisible, Spinetta Jade, and Spinetta y Los Socios del Desierto. In Argentina January 23rd is celebrated as "Día Nacional del Músico" (National Musician's Day) in honor of Spinetta's birth Spinetta devoted himself fully to his own music. In his lyrics, there are influences of multiple writers, poets and artists like Arthur Rimbaud, Vincent van Gogh, Carl Jung, Sigmund Freud, Friedrich Nietzsche, Michel Foucault, Gilles Deleuze, Carlos Castaneda and Antonin Artaud, who has his name in the album Artaud. In December 2011 he announced that he had been diagnosed with lung cancer. He died on 8 February 2012 at the age of 62. His ashes were scattered in Buenos Aires in the waters of the Río de la Plata, according to his last wish.

Almendra composed their own songs and their lyrics were written in Spanish, something which was still new for Argentine rock music. After two albums that were received with critical acclaim and continuous radio diffusion, the band split. After a lengthy stay in Europe, Spinetta returned to Argentina and afterwards formed a new band: Pescado Rabioso. With a far more powerful sound and expressing through their songs and lyrics the tension of the streets in an increasingly violent Argentina, Pescado made their album debut in 1972. It was both a continuation of the creative stream of Spinetta and a drastic change in the style of his own music and lyrics. Later, the band recorded a second album. Although a third album, released
