Qatsi trilogy

The Qatsi trilogy is a series of three non-narrative films produced by Godfrey Reggio and scored by Philip Glass. The trilogy includes Koyaanisqatsi (1982), Powaqqatsi (1988), and Naqoyqatsi (2002).

The titles of the films are derived from the Hopi language, in which the word translates to "life". The series was produced by the Institute For Regional Education, who also created the Fund For Change.
