I wasn't a huge fan of his first album (most of it just didn't grab me, and I listened at least a dozen or more times) but I do appreciate what he's doing. He's not cookie cutter, in other words, which counts a lot for me.
Bird is an AMAZING whistler, btw. That something nobody does on the indy/rock/pop scene. I could easily imagine that concert being a great spectacle at the Civic Opera House in Chicago.
