Okay, I'll start
The band -- it's lousy. Isn't loud enough, doesn't have enough brass in it, and plays extremely boring, outdated, bland songs.
My solutions, keeping in mind that I don't know music or acoustics well enough to recommend any technical improvements, so I'm just going based off what I know:
1). Stop this crap where they send a tiny section of the band (~10 people) to random sections across the stadium and play the fight song once. It's dumb in so many ways. First of all, it distracts people from actually watching the game (duh), and second of all, it dilutes a band that's already not loud enough.
2). Get better, meaner songs. Everything the band plays is soft, easy-listening, and care-free. This is a football game, not a night of the Carolina Shag down in Wilmington. Get mean. Some SEC bands used to play "Iron Man" a lot between plays or on a key defensive third down. That's pretty cool IMO. The Imperial March from Star Wars would work too (I think we've played the latter a few times, but they're so hard to hear, who knows). Play some heavier, louder-sounding stuff. "Carolina In My Mind" and "Sweet Caroline" have no place at a football game. Be creative, come up with new songs. What the band plays (fight song excluded) is one of the main reasons why the gameday experience feels very, very stale at Kenan.
