There's certainly a higher echelon of artists who are making a living out of the music industry, but the reality is that probably 80% or more of artists are not making a living solely based on the music industry. They might have a cottage industry business on the side that's not related to music. They may even work part-time. In fact, most of the artists I know—and perhaps you can jump in here at any point, Steve—have some type of part-time job that takes them away from properly building their career.
