The Qatsi trilogy is the informal name given to a series of three films produced by Godfrey Reggio and scored by Philip Glass: Koyaanisqatsi: Life out of balance (1983), Powaqqatsi: Life in transformation (1988), and Naqoyqatsi: Life as war (2002). The titles of all three films are words from the language of the Hopi people; ‘qatsi’ means life. See Also: Baraka (1992) – an experimental documentary film directed by Ron Fricke, cinematographer on Koyaanisqatsi, and Chronos (1985) – an experimental film about the passage of time on different scales, also by Fricke.
