Although it was one of their earlier releases, I didn't buy it until recently. I already have all their other cd's, which I love, so I figured I better get this one as well. What a great idea! I love this cd! You can tell that they love what they do and I know that a lot of people appreciate that! They are all amazing and very talented guys and I am so glad I bought it, finally!If anyone has not seen them live, I would definitely go do that as soon as possible!
