Maybe I'll take it, just because as a lawyer I set up all the corporate structures for the artists.
From the commercial level, almost without fail, the artists are incorporated, and the first thing they learn.... People come to me and say that they think they need a lawyer, and I tell them they always need a good accountant first. Always. Learn how to manage your money. Learn how to monitor it. Get a corporation set up. The tax rules for small business work terrifically for artists, who are cash-driven small business kinds of operations. You have to have enough money to take advantage of it, but in that real commercial aspect of it, as a small business, there are lots of small tax breaks for them to average things out.
