As mentioned earlier, there is a new Waits biography to be published by Omnibus Press. According to Amazon.com
the release of The many lives of Tom Waits is scheduled for November 1. The author is Patrick Humphries and if the number of pages (400) is anything to go by, this new book looks to be more extensive than Humphries' previous work, Small change - A life of Tom Waits
