Liberation Music Orchestra is a band and jazz album by Charlie Haden released in 1970. The inspiration for the album came when Haden heard songs from the Spanish Civil War. He included three of those songs on the album (the trilogy "El Quinto Regimiento", "Los Cuatro Generales", and "Viva la Quince Brigada", which are old Spanish folk songs given new words during the war.
Other tracks on the album include Ornette Coleman's "War Orphans", which Haden had played with Coleman in 1967, three pieces by Carla Bley, who also contributed much of the arranging, two of Haden's own compositions, one dedicated to Che Guevara and one inspired by the 1968 National Convention of the U.S. Democratic Party. In "Circus '68 '69" the musicians are thus divided into two bands in recreation of the events on the convention floor.
