What you can do is start your business as a musician. You can open a seperate account or not, as long as you keep records. Then you can show a loss as a musician, especially after you write off the equipment. You can show a loss for a limited number of years (I don't remember the number) without a problem.
Of course this loss reduces your net income for the year and you pay less taxs. It's all legitimate and you are entitled to it, since you do receive money for playing and you are entitled to write off the expenses.
Turbotax software works very well.
