The Band Program dates back to the late 1800s, having performed for dignitaries at the towns train station. The school's Homecoming Celebration gradually grew to a major event that drew national talent, such as Louis Armstrong, and over 20,000 guests, which included a homecoming parade competition for high school bands and the Cinderella Beauty Pageant.

While at the University of Texas Rio Grande Valley, Dr. Drobnak started a new festival at the end of year called, "Tuba de Mayo."

Some of his favorite performances are listed to the right.
