Just curious. In looking around I was surprised that there was not more info out there. Is there some authoritative resource or website on the ins and outs of how to manage a rock band?
My copy of This Business of Music predates the internet, but I think that the more current editions have kept more or less up to date.
probably not a book but more on actual case studies. a friend taking MBA in a nearby college might get you material. some universities actually publish their cases studies online (though it’s not that easy to access, some just publish abstracts.)
