Thomas Truax is absolutely mad, but also one of my favorite songwriters. A New Yorker, he makes his own instruments, at least some of them, and has created a fictional universe called Wowtown. (My favorite of his albums is called Full Moon in Wowtown.) If you sign up for his email updates, you'll get a fairly detailed, fairly entertaining account of what's going on in Wowtown, as well as gig notices and so on.
I interviewed him once for Splendid.
Also, he's got a free song up here, so why not give him a spin. (You have to provide an email address to get the song.)
