Good HS bands can be very good and entertaining. Agree with the scope creep. Back in the 80's hs bands were kind of required to have at least three different shows to get through the season and not have the administration call bull shit, not to mention homecoming etc. (Fyi hs band guy and Longhorn band guy).
Well, by the time my oldest started hs band in 2003 it had become the ridiculous phantasmagoric production you see today.
Not only that, back in the day the directors would write the show, and that was before there was any software for it etc.
Now, the parents have to fork over hundreds of dollars in "membership" fees in order to have a show commissioned and consultants for color guard and percussion just for their kids to be on band.
I had many a discussion with the band director over the flaws in their business model, but he wouldn't have it.
I had season tickets for years with my friends from LHB and I can't think of a single halftime show that we watched.
Aggy sucks.
