transgression:

"Controversial Kristopher Schau loves to shock his audience, and few knew what was in store for them as they went to his concert at the Quart music festival. In the middle of the concert, a young couple entered the stage. «How far are you willing to go to save the world?» asked the young man, and without much ado, the couple pulled off their clothes. Cumshots provided the background music as the couple had intercourse right in front of the audience. A banner was raised on stage informing the audience that the couple was having sex to save the rainforest. After completing the intercourse, the couple received applause from the audience and disappeared."
