Forget the dusty sonatas, stuffy tuxes and holier-than-thou cultural attitude. In the past year, the Colorado Symphony Orchestra has blown those tired classical-music clichés right out of the water. Instead, the organization has shown itself to be a dynamic and vital cultural force in the local arts scene, with a fresh group of collaborations and a renewed push to reach untapped audiences. That includes a string of impressive partnerships with pop, rock and folk musicians, including local indie-rock heroes like Nathaniel Rateliff, DeVotchKa and Gregory Alan Isakov. The CSO has also worked with different community organizations, ranging from the Jewish Community Center to the Denver Art Museum. The group's success in redefining the civic role of an orchestra is all the more impressive considering its stormy recent history. Three years ago, the CSO was cutting musicians' salaries and wrestling with its board of trustees as it faced a million-dollar budget shortfall. It took the innovation of new CEO Jerry Kern and his wife, Mary Rossick Kern, to turn the orchestra around, and the city is richer for it.
