Oh, I have no desire to see DMB anymore. I've been to 4 DMB shows and wasn't impressed at any of them. I just don't get it, I guess. Anyway, he's really not rumored for Roo, at least as far as I can tell. Wouldn't be surprised, at all, if Skrillex was at Roo, either. I do not like the music, but I have to say that I'd be intrigued to watch the show just to see what all the hub-bub is about. It would be better if he just did the Silent Disco, though.
Jack White, Gary Clark, Jr, and the Alabama Shakes are more along whom I want to see at Roo. Just started listening to Gary Clark and he is fantastic.
