'Cough' was recorded in the late 1960's and consists of Yoko Ono coughing against a backdrop of percussion instruments and traffic noise from the outside road.

Merlin's Owner, Paul Goodrich, comments, "The performance was originally recorded on a quarter inch reel to reel. Unfortunately this was not available to work from, and I used a cassette copy, which was my only source. The cassette contained a lot of unwanted noise such as scratches, crackle and hiss. Yoko Ono wanted to keep the original character of the performance, which included background noise from the street, and some hiss from the reel to reel recorder."

"My CEDAR Series X units made the task simple and I was able to control the amount of noise removed, and the original character remained."

'Cough' was on display at The Whitney Museum of American Art in New York from December 1999 to January 2000. Other works included Ono's film 'Erection' (which was part of a structural film day titled 'Frame, Time, Surface, Material: Structural Film and Beyond') and 'Fly', 'Freedom', 'Apotheosis', 'Erection' and 'Rape', all of which were screened on January 8th 2000.
