I slept in Uday Hussein's bed - that was just so strange. Went to Saddam's palace, was in a mortar attack - crazy stuff. And like three days later you're back in traffic on Sunset Boulevard. It's all kind of behind you, which is kind of perfect for a guy like me because I can take that and turn it into quite the tale.

The fact is that I am always thinking of something to build. A new book, radio show, plans for a trip somewhere. I am not a very happy person but I feel pretty even when I am working, so I guess that is how I am wired.

One of the most prevalent and undermentioned genres of music is what is known as noise. You can find it all over the world happening in basements, small venues and even some festivals. Often blown off or belittled by critics, the form for the most part goes unheard and unnoticed.
