^I've actually gotten the opportunity to see that Blast show live, and it was just incredible.
I've been out of HS for 8 years now, but I was in marching/field show bands all the way through high school. Although, I was trombone, and not drumline. We were actually the most successful marching band in the history of Wisconsin. I do miss it a lot, and band trips were some of the most memorable times of high school.
My brother was drumline though, and now goes to school for music. He actually has some published music, and helps write the music and design the show for my old high school.
