Dream Theater keyboardist Jordan Rudess will be performing two special shows tonight at the Iridium jazz club in New York. He'll be playing Emerson, Lake & Palmer's "Tarkus," as well as original compositions, at 8 and 10 PM EST. If you're in the house, you'll be able to buy CDs of each performance immediately after the show - but if you can't get to New York, you can watch the whole thing live online! The Iridium will be webcasting each set at iridiumlive.com!
