One of the outlets for bassist Charlie Haden's multifarious musical interests is the politically charged, progressive Liberation Music Orchestra. In July 1992, the Orchestra- a powerhouse of some of the top names in jazz- brought the collaborative sound of their album "Dream Keeper" to the Montreal International Jazz Festival. The African National Congress anthem, "Nkosi Sikelel'i Afrika," opens the program and sets the tone, followed by a suite-like series of traditional melodies from Latin America for a unique, powerful performance.
