Gustavo Santaolalla, a renowned Argentine musician, rose to prominence as the leader of the bands "Arco Iris" and "Soluna" by the end of the 1960s and beginning of the 1970s, becoming a reference point for his country's national music.
In the 1970s, Santaolalla relocated to the United States, where he formed the band Wet Picnic with Aníbal Kerpel, Aaurie Buhne, and Robert Brill, and developed an intense musical activity in Los Angeles.
In 1982, he returned to Argentina to record a solo work, titled "Santaolalla", which featured a new sound heavily influenced by American pop trends of the time, and included contributions from Argentine musicians Alfredo Toth and Alejandro Lerner.
Santaolalla's work in music production was also notable, particularly on the project "De Ushuaia a La Quiaca", which followed a national folk line similar to that of Argentine musician León Gieco.
Back in Los Angeles, Santaolalla went on to produce records for various artists, including "Café Tacuba" and "Maldita vecindad", before returning to Argentina in the mid-1990s to release his second solo work, "GAS", which stood as a testament to his initials.
Santaolalla's work in group production in the USA had established him as a prominent figure in that area, allowing him to participate in various musical projects for films, including "Amores perros", "21 Grams", and "Diarios de motocicleta" ("The Motorcycle Diaries"),which earned him an Oscar award in 2006 for his work on the music for the film "Brokeback Mountain".
In 2007, Santaolalla won his second consecutive Oscar award for Best Original Score for his work on Alejandro González Iñárritu's film "Babel", making him the third composer to achieve this feat in consecutive years.
