If I wanted to start a music and film production company should I use an LLC or a sole proprietorship?

To avoid exposing your personal assets to debts of a business operation is always prudent to form a corporation to conduct business activities.  You should speak to a corporate/tax attorney to do this right.  Successful business people surround themselves with good counsel and financial professionals.
