Hello Mason Band Families!

On the verge of a new season, it is humbling to look back on the past 3 years which have taken us through some of the most challenging times in our lives. I put myself in the shoes of our rising seniors who were introduced to the marching band in 2019 with “WHAT LIES BENEATH”…playing on slides and dressed in brilliant colors! Then came the 2020 season and the pandemic which was certainly UNINVITED. However, the students forged ahead amid tight restrictions, modified schedules, and canceled competitions, and we were rewarded with one of the most special celebration days in Lucas Oil Stadium. In 2021 we took to the skies with TOP GUN, again performing on the national stage as the band returned to finals competition after the prior year’s cancellations. 

These past seasons have taught us that it is not just about the ending destination, but about the journey, the process, and the time we spend together. We look forward to establishing new relationships, strengthening old ones, and working together to create the family we call Mason Bands. We look forward to working hard, pushing each other, and pursuing excellence in all we do. We look forward to the excitement before a show, the thrill of competition, and the rush after a great performance.

We have so much to be grateful and excited for in 2022, and I look forward to embarking on our journey together!

With Pride,

Mr. Sleppy
