You could say of all the acts at the Bonnaroo music festival in Tennessee, R. Kelly stood the tallest. But not necessarily because of his music.

At one point in his set, the lights went dark and the next time fans saw the R&B singer, he was standing in the basket of a crane 40 feet above the stage.

R. Kelly's performance of the song "Ignition" also featured dozens of chorus members.
