Coming on the heels of a pauper's life of dumpster diving and living in a bus powered by veggie oil, Paper Bird teamed up with Ballet Nouveau Colorado for the grant-fueled project of Carry On, which took the former to a new world of highbrow art, writing songs for a companion ballet production. Ballet Nouveau Colorado was likewise suddenly exposed to an audience of dusty freegans, traveling by road bike to the sober world of silent dance. And we all got a new Paper Bird album out of it, 2011's Carry On. The two worlds will collide again this September, treating Denver to another round of the unlikely collaboration.
