John Harner leads his charges through a trumpet master class on the second day of the weeklong UMSL Jazz Camp, which is now part of the Jim Widner Big Band Jazz Camp series. The musicians added an extra level of improvisation that day, moving class to the naturally illuminated J.C. Penney Building/Conference Center lobby due to a power outage that hit North Campus.

Widner‘s band is entering its 26th year of hosting summer jazz camps all over the country. Members of the band serve as the faculty for the camp and teach all of the classes. Harner is a former first-trumpet player of the Stan Kenton Orchestra.
