Guitarist John Petrucci explained to Ultimate-Guitar.com
that the band were trying to set a mood with an instrumental track. "It's kinda like the idea was when we play live and before we hit the stage, we like to have some sort of like you said dramatic piece of music and something cinematic to bring us onstage," he said. "We've used the music from Psycho
before and Hans Zimmer. The last tour was a piece from the movie Inception
and just stuff that really sets the mood and you know the band's coming onstage. It was kinda like, 'Well, let's write our own. We can do this. How hard could it be?' So we wrote our own cinematic opening and the cool thing is it has real strings on it and it has that cinematic vibe but it's in the style of metal and it's kind of a progressive version of it. It's our spin on that type of opening."
