 Throughout their career, Dream Theater's live shows have gradually become bigger, longer and more diverse.Prior to Portnoy's departure, Dream Theater "rotated" its set lists to ensure that fans who attended multiple shows in the same area would not see too many (or any) songs repeated.Portnoy, who constructed the set lists, would take into account the set list from the last time the band was in a particular city for the benefit of fans who saw the band on successive tours.
