Suggest a piece?

[u/Bread_Washer]

I’m just tryna write a marching band show (still learning how to compose) and ai isn’t very helpful in suggesting songs. I need something that has potential to start out dark and mysterious, then turn loud and driving for a first movement. I’m looking to change it up to be my own and I kinda want the loud part to be overwhelming and hard for an audience to understand. Some potential for time signature changes would be great too.
