Cold Play
Jul 13 was the Cole Play concert. I was at the balcony overlooking the path that divided lawn from assigned seating and noticed that security was assembling. They cordoned off a line on the walkway and I knew something was up so I got as close to the rail. The band moved from the main stage to a stage that overlooked the lawn. Then at the end of their set they walked right by me. They were so close that I could have tapped them on the head if I'd reached out.
This is a video of one of their songs. It looks like the whole thing was recorded backwards, including his singing.
