As the Colorado Symphony prepares for the arrival of new music director Jeffrey Kahane, comparisons to outgoing MD Marin Alsop are inevitable. Alsop rose to international acclaim during her time in Denver, and the CSO caught some of the attention as a result. Kahane, by contrast, has never topped any overblown lists of conductors thought to be “the next big thing,” but he is quietly beloved by musicians, audiences, and administrators nearly everywhere he conducts. He doesn’t micromanage his orchestras from a musical standpoint, but behind the scenes, he seems to have his hands in nearly every facet of the organization.
