Roger Waters and crew just did a small US Tour not too long ago. I went to the show in Houston and it was absolutely epic. Definitely in my top 3 concerts of all time, along with the time I saw Pink Floyd in 1994 in Houston as well. The Roger Waters show was great though. They played all the Floyd songs you really wanted to hear and the entire second act was Dark Side from start to finish. The singer they brought along for Great Gig in the Sky absolutely killed it. Also, during the performance of Sheep they brought out a HUGE pink pig balloon with Obama this and Bush that messages on it. They carried it back and forth through the crowd on the hill and when they got to the top they released it and it let it fly up in to the night sky. What an amazing evening that was!
