One of Kansas City’s most recognizable contributions to American culture appears as part of a new documentary titled “Jazz.” Creator Ken Burns appeared at Kansas City’s Gem Theater this week to promote the project and says it energized him as he continues a nationwide tour. He says Kansas City’s influence on jazz began with musicians in the 1930’s. He says they flocked to Kansas City, even in the midst of the depression, and helped re-invigorate swing. The series is being shown on PBS television stations throughout the country.
