Los Prisioneros were a Chilean rock/pop band formed in San Miguel, Santiago, Chile in 1979. They are considered one of the most important Chilean bands, and arguably the strongest musical influences that Chile has made to Latin American music. In addition, they are considered by Latin American media and musicians pioneers of Rock en espaol and the band with strongest socio-political impact in Chile. Their roots date back to March 1979, when their core members entered high school. From their beginnings in 1983 at the Festival de la Cancin del Colegio Miguel Len Prado to their first limited release album in Chile under the record label "Fusin Producciones", they struggled to make themselves known until they were able to sign with EMI Records in 1985, re-releasing their first album on LP record and cassette. From that point on, they reached mainstream success in Chile, then in Peru. Los Prisioneros created a simple Punk sound with a mix of Nueva ola, Techno, Synthpop, and Reggae.
