My band is going to record on saturday downstairs. My dad has a fairly nice demo studio. The one thing I'm concerned with is that downstair the floor is not THAT well open ended. I want to move a shelf downstairs to make room, so we could all see each other. The problem is that this shelf contains some prized stuff for my dad. I would really like to move this, but it has quite a bit of stuff, and I think if I move it on my own he would get mad at me. Very very minute detail I know, but what would you suggest I do?
