Ben Folds

Singer Ben Folds ditched his rock band and back-up singers, and has gone on tour with just a solo piano. He shares with us the discovery he made on the road: The audience was ready and willing to become the band. They sang the harmonies, the horns, drums, guitar — everything — perfectly in tune, night after night. He says that once you give permission for people to sing together, a magical thing can happen in a concert hall.
