When I lived in Ann Arbor, we were in this shitty apartment on the ground floor. One night I came home to 2" of water in the entire apartment. I had vinyl records on the floor, my Hammond C2 and Leslie, etc. But that's another story.
Anyway, yes I had a Hammond C2 and Leslie in the apartment to practice on and I put the Leslie in the corner, one wall of which was the "shared" wall of the apartment next door. The folks that lived next door were a pair of 70+ year olds that never left their apartment and their total loser of a son, who had to be approaching 40 but lived with his parents and smoked pot all day. But man, did he have an awesome Camero!
So all day, every day, all I heard from their apartment through the walls was the TV. It was always on and it was always blarring. One afternoon I'm practicing the organ and they start yelling at me through the walls to stop. It is 2pm in the afternoon. I keep playing. They start getting mad and pounding on the walls. I yell, "What's wrong? Can't hear the goddamn TV?" Then I play even louder. They threaten to call the cops. I said, "Go ahead! It's 2pm in the afternoon!"
This went back a forth a bit but never really escalated. A few months later the flood happened and we got the hell out of that place. I always wanted to wake up really early on a Sunday morning (like 5am) and start playing church hymns extremely loud for them, but I never did.
