Welcome to the 2019-2020 Season of the Ontario Chaffey Community Show Band!  This marks 35 years since Jack Mercer came out of retirement to form an alumni band of forty-two musicians.  They represented a wide variety of occupations from doctors, lawyers, dentists, mechanics, educators, the Chief of Police and other professions and began what would become known as the Ontario Chaffey Community Show Band.

Gabe with the fantastic Jim and Anne Curry just before the "Country Roads" concert on January 21st, 2019!!  They were truly outstanding in a wonderful 5 song set paying tribute to John Denver!  Thank you Jim and Anne!!

For the past thirty five years, the 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:  Dave Schaafsma and Pat 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.

We're excited to start this season off on August 14th at the Ontario Town Square with "Summertime with the Show Band" featuring the outstanding musicians of the Show Band, including a host of exciting instrumental and vocal soloists.  Our first indoor concert will be held at historic and newly renovated Gardiner Spring Auditorium on Monday September 9th, featuring renowned Jazz artist and educator Aimee Nolte.  Other special guest artists during the concert season include Grammy-nominated trumpeter Bobby Rodriguez, former singer with The Drifters Ron Ellington Shy, and concert pianist Dr. Maria Perez who will perform "Rhapsody in Blue" on the March 2020 concert.

The Ontario Chaffey Show Band relies on the generous donations of sponsors and financial support from the City of Ontario to help keep our programs running.  Additionally, a non-profit organization called "The Friends of the Ontario Chaffey Community Show Band" helps to provide assistance to the Show Band.  If you enjoy the Show Band performances, please consider making a tax-deductible and secure payment via our PayPal account, conveniently located on left side of our website.  Or, mail your donation to: Friends of the OCCSB at P/O Box 1512 Ontario, CA 91762.  Your donation helps to keep music alive in the community!
