The 1967 Cheetah club packaged the whole avant-garde as available for consumption.

Evidence

In addition to “a giant dance floor and a main room seating 1,800,” Vincent Canby reported in the New York Times, “Cheetah will have other rooms, upstairs and down, devoted to television, Scopitone, esoteric publications and movies in the Andy Warhol-Batman genre, plus a street-level boutique offering ‘mod’ merchandise.” — J. Hoberman, Everything Is Now, 1947

• QUESTION: Cheetah is the commercialization endpoint — does its opening date bracket the scene’s transformation from underground to market?
