Maybe this old video by Todd Rundgren explains how to make money on music today, or not:
Meanwhile, if someone really wants to make a living or even a profit, touring is the way to generate money, not selling records.
However, there’s a really cool spin on actually even making money on records. Press 500 or so special CDs that you sell at concerts, before or after, for $5 or so. It should not be hard to sell them, especially if they have exclusive content such as concert recordings or otherwise rare or brand-new tracks. Add into it your signature or something similar and it’s an easy way to generate revenue. Anyway, I would do it if I would be on an extended tour. The audience loves exclusive stuff, CDs, T-shirts et rest.
