Dream Theater

I just put this in for the first time (didn't really see the need to watch it since I'd already seen it in the spring)... does anyone know what song is playing on the menu screen as soon as you pop in the DVD?

The song played on the main menu is the badass heavy riff song written by DT for the auditions. It was one of the songs used for the drummers to play during the "riff test".

What I wish is that a) they used the whole song, and b) the used that riff in an actual song, because it's FOOKING BROOTAL.

I'm also wondering who it was playing that riff on the recording on the DVD. You mostly only see Virgil playing that song, whilst Mangini got the job. On the main menu it doesn't sound like Virgil though, so i'm assuming it's Mangini's playing.

Anyone have any ideas?
