Chris Koza. Chris Koza is a composer and performer based in Denver, Colorado and Minneapolis, Minnesota. In his writing, Chris both honors and builds on the vast genre of Americana music. For every song that sounds like it could be strummed from a boxcar clacking slowly across a grassy midwestern plain, there's a tune sailing from a city rooftop, echoing across a valley of streets and traffic, or a melody twisting and shimmering like a dim frequency deep into the starry night.
