own song "As I Am". Perhaps the best example of Dream Theater's unpredictable concert structure came during Derek Sherinian's time with the band. At selected shows the band members all swapped instruments and performed an encore as the fictitious band dubbed Nightmare Cinema. They usually performed a cover of Deep Purple's "Perfect Strangers," and, on one occasion, Ozzy Osbourne's "Suicide Solution," At some shows, Sherinian, Petrucci and Portnoy would take the stage together under the name "Nicky Lemons and the Migraine Brothers." Sherinian, wearing a feather boa and novelty sunglasses, would perform a pop-punk song titled "I Don't Like You" with Petrucci and Portnoy backing. During the Chaos in Motion tour, in several concerts before "Trial of Tears," Portnoy and Petrucci would change positions. In the Score and Chaos in Motion DVDs, an animation has accompanied certain parts of the songs, showing the band playing along to the music as cartoon characters. On the Score DVD, during the song Octavarium, the band is seen performing in an octagonal shaped maze. As the animation continues Jordan Rudess spontaneously turns into Santa Claus and John Petrucci catches fire. In "The Dark Eternal Night" from the Chaos in Motion DVD, the band battles against a monster by shooting fireballs from guitars, throwing drum sticks, and screaming. Shows and concerts Dream Theater played and recorded a live performance at the Nippon Budokan Hall on April 26, 2004. It was later released as Live at Budokan on October 5, 2004. Dream Theater's largest audience as a headlining act was 20,000 in Santiago, Chile on December 6, 2005. The show was released on DVD through Portnoy's YtseJam Records. In 2007, after their show in Salt Lake City on July 30, Governor Jon Huntsman, Jr. signed a proclamation officially marking July 30, 2007 as Dream Theater Day in the state of Utah. In 2008 Dream Theater started the Progressive Nation 2008 tour, along with Opeth, Between the Buried and Me, and 3. The tour is the brainchild of Mike Portnoy, who stated, "I've been wanting to assemble a package tour like this for many years now. With all of the festivals and package tours that go through America, I've been talking with our manager and agent for over 10 years now about doing something that focuses on the more progressive, musician-oriented side of hard rock and metal. I decided it was time to stop talking the talk,
