I've noticed there's very little mention here of Godfrey Reggio's trilogy of non narrative films Koyaanisqatsi, Powaqqatsi
& Naqoyqatsi. The first of the series, Koyaanisqatsi, is legendary for it's iconic use of slow motion and time-lapse cinematography, later replicated by the films cinematographer Ron Fricke in his film Baraka (another cult classic overlooked here). Also notable about Reggio's trilogy is their musical scores by Philip Glass.
Surely many of you have heard of these films as they are often a staple of art house cinemas, but if not - you owe it to yourself to investigate them. Koyaanisqatsi at least is surely one of the most influential cult classics of all time. Countless directors, especially documentary makers, have borrowed techniques that these films helped pioneer.
Anyway, curious to know who has seen them, what your thoughts are.
