I think part of the equation is being able to make a living wage. An earlier post made a great point about 90% of band proceeds coming from touring. That’s a killer. How many musicians that also have lives can spend that much time on the road in their mid ‘30s?? Most Huge bands like Zep were on autopilot collecting royalties by then. Those days are long gone. It’s amazing to me anyone bothers to try music as a profession anymore.
