For almost four decades the Show Band has been performing one free concert a month for the Greater Ontario Community, bringing in an array of talented guest artists as well as providing musical performances for various city-sponsored events.  The Show Band is directed by Dr. Gabe Petrocelli, esteemed composer, arranger, and conductor, and two assistant conductors:  Mr. David Schaafsma and Mr. Patrick Arnold.

The Show Band continues to grow as we add tremendous new talent to our band.  We feature many of our own musicians as conductors, vocal and instrumental soloists, and also welcome a talented array of guest artists to our programs on a regular basis.
