"ordinaryguy" - If you have never seen The Machine, you should keep your comments in check until you watch the show. I have seen them play alone and with ASO and I can tell you first hand it is phenomenal! You can think of them as a tribute band, but once the music starts you will be pleasantly surprised, especially if you're a Pink Floyd fan. Don't knock it until you see them. They are no "ordinarytributeband". If this was Zoso or Appetite for Destruction I might agree with your tribute band comment.
