Rage Against The Machine star Zack De La Rocha is still proud of the band's infamous naked protest at Lollapalooza in 1993, even though pranksters in the crowd pelted their privates with coins.
The Killing In The Name hitmakers stripped off and stood naked onstage in front of thousands of revellers at the event in Philadelphia before walking away without playing a note of music.
The headline-grabbing stunt was staged to protest against bosses of the Parents Music Resource Centre, who were calling for a ban on explicit content in music, and De La Rocha still has painful memories of the day.
He tells NME magazine, "The performance that day was more, um, performance art than a rock concert. We appeared completely naked onstage with the letters P-M-R-C written on our chests, which stood for Parents Music Resource Centre - an organisation of Washington wives who were trying to censor rock and rap music.
"We had duct tape across our mouths, we let the guitars feed back and then we left the stage. That was the entire show. The point that we were hoping to make was that you can't always take it for granted that you'll be able to hear music that challenges the status quo. People are trying to rob you of those first amendment rights. But let me tell you - a lot of quarters were thrown at our d**ks."
