And there's a big part of me that wishes I hadn't followed the instructions to just suggest *five*... :) I've been listening to Tom Waits since the late 70's, and I still think that Bone Machine (around 1992, I think) is his best work ever.

I also love the blues--all types, but I didn't want to inundate you with suggestions about Buddy Guy, Albert Collins, et al. without knowing whether or not the blues appeals to you. However, I had to add in SVR because he redefined the blues in the 80's and is required listening. The man was amazing.
