I follow their band on Facebook and I feel confident the directors did a workshop either at tmea or tba. I don’t feel like going back through the page but I’m positive it was them.
interestingly enough, their show designer also designs for North Lamar, and I think maybe Kaufman, wakeland, Ranchview, and Melissa. Maybe a few more big schools? I cannot remember. It definitely starts with a solid show design but is also about the band leadership, instruction, and execution.
