That too, but the thing about great art, it tends to come from a place of pain and misery. Artists who tap into that, are rarely happy.
But if they last long enough, and don't join the 27 club, they tend to either get help, or at least find some way to achieve a modicum of peace. There are a couple notable exceptions, who found no peace, and who either didn't get help or didn't get enough help...
I prefer to think of it as coming from a place of need rather than distress, as many modern musicians really don't have much in the way of trauma. I do agree that most leaps in music were the result of broken people, though. Sanity and stability don’t offer much in the way of novelty.
