…There seem to be more ways than ever for the independent artist to bring in cash. The Future of Music Coalition, an artist lobbying group, announced during SXSW the results of two years of research into how musicians make money. Jean Cook, one of the architects of the project, said the research revealed 42 potential music revenue sources. No single artist is, of course, benefiting from all 42. A classical artist, for instance, may have access to only two or three, she said. But a singer-songwriter may be able to pull from as many as 25 revenue streams.
