If the video shown behind the band during a 1680's Butthole Surfers show counts I'll throw that in as well. They actually managed to drive about half the audience out of the venue...
go on...
After Gibby gave up squirting lighter fluid at the crowd and trying to set shit on fire the started showing a series of movies behind them. The visuals started out kinda goofy with cartoons and altered footage of Tanya Roberts running in a scene from her stint on "Charlie's Angels" contibued on to innocuous footage of bugs eating each other and then nuclear testing footage. We then go to some graphic footage of car accidents and mangled people, bodies without heads, heads in search of the bodies they once occupied. Kinda like the original cover to Big Black's "Headache" e.p.. Near the end of the show the screens behind them went dark red for about five minutes. A camera pulled back revealing the red to be a blood soaked... cotton or something. Eventually the footage became a man, his cock in close-up, with the skin being pulled back, pulled forward, pulled back again and various muscles being sewn together. Once the skin started being pulled back people left in droves.
Several years later I read an interview in which they said the footage was from a medical film in which a man was having his cock reattached after being caught in farming equipment...
If you remember late 80's Butthole Surfers you should get the picture... They were such a great band at one point...
