Here is a great article by Ellery Eskelin that is almost ten years old now but still very clear and effective regarding the life of a creative jazz musician. It covers, making records, leading bands, making money, being yourself. I think any artists could take a lot from this article, actors, dancers, film makers etc. Check it out here thanks Ellery!
