I was in band, and marching band was mandatory.

I did not try out, as I did not want to participate in that part of the band experience.

So I was part of the “front ensemble” which is shit you can’t march with. Timpani drums, etc.

We had an L frame rack with wheels that had all sorts of crap on it, half of it made in some garage before I joined.

We called it the ghetto rack.

I had a solo on what were essentially tanks that had the bottom cut off and an attachment point welded on top hung by rope.

So yeah, if you can hit it and make a sound, it becomes a percussion instrument.
