Ben Folds Five

Ben Folds Five plays “The Unauthorized Biography of Reinhold Messner.” Sounds like some weird concept piece at an arthouse, right? But it was actually a sold-out rock ‘n’ roll show Monday night at the Park West. You wouldn’t know it from “Brick” – the band’s breakthrough, bittersweet single in which Folds sang about an abortion his high school girlfriend had – but the group has a wry sense of humor.
