If you've not checked out his narration of A Brief History of John Baldessari, check it out.The ungovernable state of his room became part of the legend. Barney Hoskyns, in his excellent biography, Lowside of The Road, quotes a friend of Waits's, who opened the fridge in search of a beer, and found only "a claw hammer, a small jar of artichoke hearts, an old parking ticket and a can of roof cement."
This fits perfectly in to my vision of what Tom Waits is like. I find it an endearing quality because each of the objects in that fridge are pretty common and simple but when in the same sentence are really odd.. especially as contents of a refrigerator. Waits' music is like this imo. Lots of simple components but when they're all put together, they seem strange -in the best way.
