Speaking of essential reading, Don Passman’s industry bible All You Need to Know About the Music Business will be released in its eighth edition Dec. 4. Be assured the dust jacket will be loaded with endorsements from high-profile figures. For example, Katy Perry says, “I read this book when I was 13 and then things turned out okay for me.” Passsman’s client Tom Waits offers, ”I’ve spent years trying to get Don to open up like this to me. Never has he been so eloquent, so patient, or so thorough. It cost me a fortune to get these diamonds from Don: Now you can have them. For your own. At a fraction of the cost.” And Adam Levine cuts to the chase (he’s busy), stating, “If you want to be in music, you have to read this book.” [HitsDailyDouble]
