As head of CD Baby, Derek Sivers has been a go-to person on the web and at conferences for musicians looking to learn how to make it in the biz. Having recently sold CD Baby to Discmakers, Derek Sivers has begun work on a bunch of new projects, all with the similar goal of helping artists. They seem to be in the planning stages, but you can go to his website and sign up for announcements and see what he’s got cooking.
Also, you should download a FREE e-copy of his Music Marketing Advice book.
