Can't say I'm familiar with him, but I've heard of him. I believe he's from the Twin Cities area (of Minnesota) and our local PBS affiliate did a story about him a few years ago that I happened to catch. Practically the only thing I remember about him was that he was an observant Jew and, in one of those "slice of life" backstage scenes, he was trying to explain the Jewish dietary laws to someone.He has an official website www.peterhimmelman.com which I found rather maddening to try to navigate, but it does have some tunes you can play.
His record company's site is more user-friendly. Here's another one. The Judging Amy website has some information about him, too. Google will find lots more.
