Ben Folds quite seriously rocked the house. He loved playing in a place as nice as Severance Hall, and with such great acoustics. He kept using various sections of the audience as instruments. I missed a bunch of the show, but he played a LONG time. I'm writing this in the distant future, but a highlight for me was Video Killed the Radio Star.
