Leon Gieco was born into a family of Italian origin on November 20, 1951, in Cañada Rosquín, Argentina. At 6 years old, Gieco traveled with his family from the field to the village center due to economic problems. At age 8, Gieco bought his first guitar on credit, and soon began playing music at local events with his father's band. Throughout his childhood, Gieco played with local bands such as a folkloric group called Los Nocheros (The Night Watchers) and Los Moscos (The Flies), a rock band that gained some popularity within Argentina. In 1965, Gieco traveled to Bolivia as an exchange student. He studied music and played guitar at local festivities.
When Gieco turned 18, he went to Buenos Aires to become a full-time musician. There, he took guitar lessons from Gustavo Santaolalla, who introduced him to important people in the Buenos Aires musical community, such as Raúl Porchetto, Charly García, Nito Mestre, and María Rosa Yorio, future members along with Gieco of the Argentine supergroup, Porsuigieco. Gieco was given the opportunity to perform in the Buenos Aires Rock Festival in 1971, 1972, and 1973. In 1973, he recorded his first album, "Leon Gieco" ( it was recorded independently with Santaolalla). "En el País de la Libertad" ("In the Country of Freedom"), a hit from his album, demonstrated Gieco's concern for change in Argentina, his concern for social justice.
In 1976 Gieco released El Fantasma de Canterville ("The Ghost of Canterville"). The record suffered a great deal of censorship from the military government forcing him to change the lyrics of 6 songs and remove 3 others altogether. Nevertheless, the record was a success, and he had concerts not only around Argentina, but also in other countries of South America. Two years later he released IV LP, with one of his most famous songs: "Sólo le pido a Dios" ("I only ask of God"). Due to the political situation in Argentina, Gieco was forced to move to the United States and Italy in 1978 for one year. In the US he lived with family friends in Los Angeles and Ann Arbor, Mi. While in Ann Arbor, he performed at the famous Art festival in the summer of 1978.
On December 20, 1979, the Argentine Minister of Education announced the closing of the National University of Lujan in Buenos Aires. Gieco participated in a protest against the closing by singing "La Cultura es la Sonrisa". His lyrics say, "(Culture) only cries in a country where people can't choose it/it only cries its sadness if a minister closes a school..."
In 1981 Gieco started a 3-year, 110,000-kilometre-long series of independent concerts all over Argentina, playing for a total of 420,000 people. He gathered material from the different places he visited during the tour, and recorded the first volume of De Ushuaia a La Quiaca ("From Ushuaia to La Quiaca" in Buenos Aires with various autochthonous musicians in 1985. The following De Ushuaia a La Quiaca 2 and De Ushuaia a La Quiaca 3 were recorded in a mobile studio in different locations of the country.
In 1985, Gieco went to Moscow for the 12th "World Youth and Students' Festival" alongside Juan Carlos Baglietto and Litto Nebbia, representing Argentina. In 1986 and 1987, he held concerts in Germany with his friend Mercedes Sosa, including that of Berlin's Political Song Festival.
After eight years of touring, Semillas del corazón ("Seeds of the heart") marked his return to the studio in 1989. That same year he performed at the Teatro Ópera in Buenos Aires with the American folk legend Pete Seeger. The following year, Seeger asked him to join a tour that took him to Washington, D.C., Boston and New York City. There he played with David Byrne, whom he had met in Buenos Aires shortly before.
Gieco began his most recent national tour for social justice, Mundo Alas, in 2007. Argentine musicians, dancers, singers, and painters, all with disabilities, performed alongside Gieco, expressing their unique talents and communicating with audiences. He gave these artists the opportunity to live out their dreams as he does. Gieco created a documentary from the road tour which was produced in March, 2009. The film features rock music, folk music, and tango, along with Gieco's original hits.
