Redención 9-11 was a left wing hardcore punk band from Santiago, Chile. The band performed existed between 1997 and 2002. The band's name is a reference to the September, 11, 1973, Chilean coup d'état in which the democratically elected government of Salvador Allende was overthrown by a U.S.- backed military Junta. Throughout their existence, Redención 9-11 was openly critical, both through their lyrics and commentary during concerts, of the military dictatorship and the influence of Chile's center-right and right wing political parties as well as the conservative wing of the Catholic Church. The band played mostly in Santiago and other Chilean cities such as Valparaiso, Chillán, Concepción, as well as brief tours to Argentina and US east coast.
