Tom Waits.
New album, Real Gone. On Rhapsody, the mini-review: "Real Gone sounds like the cut end of corrugated metal: in other words, it's instant vintage Waits. -- Sarah B." Granted, the review was probably written by someone who considers Bone Machine vintage Waits, but a good assessment. Not as good as Mule Variations, but there you go.
"There's only one reason you write new songs. You get sick of the old songs." Tom Waits.
