The DC Defenestrators staged a concert on the mall in Washington DC using rock band instruments.
They write:
After we set up a giant crowd had gathered waiting for us to start. With a 1 – 2 – 1, 2, 3, 4 the click-fest began and the crowd let out a nearly unanimous laugh – then cheer at us as we thumped and clicked away.
I wish the video had less of the video game sound track and more of what the participants heard. I think it detracts from the utter absurdity of the mission. The average YouTube visitor is not going to get this. They are just going to think the agents were just playing along to a boombox.
