 The band's full world tours, since "Six Degrees of Inner Turbulence", have predominantly been "Evening with..." tours, in which the band performs for at least three hours with an intermission and no opening act.The show that was recorded for "Live Scenes From New York" was nearly four hours in length, and resulted in Portnoy almost being hospitalized after acquiring severe food poisoning from the food he ate before the show.There is also a significant amount of humor, casualness, and improvisation attached to a Dream Theater concert.
