Professional marching band

So I don't know if you guys know this but, yes there is a professional league of marchin bands (brass instruments only (trumpet, baritone, tuba) (it also is only for those aged 18-22? Sadly.) and its know as DCI (drum Corp international) and I've sorta become obsessed with one of the groups show, the group is called the Blue Devils, and the show is called down side up. It's AMAZING they are the grand champions this year and they earned it. They have go-pro videos of the show of multiple instruments view points and I've been nonstop watching them. I highly suggest you watch them and consider getting tickets to one of the DCI shows :) (I had to get this off of my chest because I felt like some people on this site would really enjoy this)

*bluecoats and I call myself a fan

I was always a Blue Devils fan, but I had friends who marched Phantom Regiment and a close friend was drum major for Blue Knights for two years.

You can actually join at 15 (?) I think? Unless they have changed the age requirements in the last few years.

I love em! I'm a total band geek, but I'm not a brass player. I would love to be in a college band once I get to that point lol c:

Oh, I love the Bluecoats. XD
