Luis Alberto "El Flaco" Spinetta (23 January 1950 – 8 February 2012) was an Argentine musician. As one of the most influential rock musicians of South America, together with Charly García is considered the father of Argentine rock. He was born in Buenos Aires in the residential neighbourhood of Belgrano. During his early childhood he was already listening to all kinds of music: folklore andtango, and a little bit later, rock. In 1967, amidst the repressive political climate, he formed a band called Almendra with his schoolmates.
Contrasting with the backwards and authoritarian government of General Juan Carlos Onganía, Buenos Aires was undergoing a cultural blossoming based on new art expressions; the new generation, among sons of the middle class, were immersed in an effervescence that would not reappear in Argentina until 1983. 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.
On 23 December 2011 he published on the Twitter account of his son Dante that he was facing lung cancer. He died on February 8, 2012 in his native Argentina, at the age of 62. His ashes were scattered in the waters of the Río de la Plata, according to his last wish, next to the Memory Park built to remember the desaparecidos of the National Reorganization Process.
