From 1967, Canadian avant garde filmmaker Michael Snow’s single-shot movie runs 45 minutes in length. Wavelength consists of a glacially slow tracking shot across a mostly empty NYC loft. The sound of a sine wave and the final destination of the shot are linked conceptually, but the movement is blissfully free of narrative. All the tension comes from the pitch of aural tone and the incremental progress toward the loft windows (though not out; escape isn’t the object here). It’s a fascinating, hypnotic film, and far easier to endure than Warhol’s Empire. It’s paired with his shorter 1976 Breakfast, in which the camera finally gets too close to the morning table.
