Yalkut's film is the only record of Nam June Paik's legendary 1967 performance Opera Sextronique in New York, which was interrupted by the arrest of cellist Charlotte Moorman, who was performing topless. The incident led to Moorman's subsequent notoriety as the "Topless Cellist." This restaging of the first two movements of Opera Sextronique, performed by Moorman and filmed by Yalkut in a studio, was shot immediately after the arrest incident to present at Moorman's trial. (The judge did not permit it to be shown in court.)
