National Geographic Magazine, July 1969, Vol. 136, Issue 1.
Four exposures on a single frame re-create the psychedelic phantasmagoria that assaults the senses at Montreux’s hard-swinging Strobe Club, where young Swiss gyrate to the recorded rhythms of musical groups such as Canned Heat the Grateful Dead. Jean-Pierre Kolly manipulates projectors, flashing lights, and other devices to create his weird “mind-flowing” effects. Downstairs, in the Pavillon, more sedate audiences attend classical-music concerts.
