Dan Bern is a wildly imaginative troubadour whose music was described in the New York Times as "topical-political-poetical-sarcastic-punk-folk." His brilliant free-form poetic lyrics and the power of his raging tenor often generate controversy as he veers from comedy to anger, conjecture to shaggy-dog stories, with side trips to theology, science fiction, consumer culture, love, art, and baseball. The Iowa native has spent his adult years traveling the country, writing hundreds of songs, and performing them for an ever-expanding audience. He has released six albums, most recently last year's New American Language (Messenger). Opening for Dan are Chris Chandler & Anne Feeney on Tuesday and John Vecchiarelli on Wednesday.
