I am also curious about the unknown songs. I suppose they are just from the new album, and he didn't bother presenting them. I agree that it would have been nice had more Terria material been played, but I understand that it would have been hard to pull off live. I was somewhat disappointed with the sound on Earth Day, but it was amazing live nonetheless. I can't wait to see SYL in a few months...that is if I am able to make it. I thought about trying to see that show in Atlanta, but I will probably venture up to DC and go with a friend.
