Alrighty, bump-update.
It's been more or less confirmed that the short opening piece, "False Awakening Suite", IS all instrumental as no lyrics have been listed with it on the vinyl package preview posted on the pre-order pages.
We know "The Enemy Inside" is NOT the instrumental because it's the first single off the album, and we know it has lyrics. And given that the 7" clear vinyl single in the Box Set is the song "The Bigger Picture", I doubt that would be the instrumental, especially if it's in the running to be the 2nd single off the album.
Also, given that the stems for "Behind The Veil" are included, I would assume they wouldn't include stems for the instrumental given that the last time they gave out stems was for their first single off their last album in the form of "On The Backs Of Angels", and I think having stems for all FIVE members would be cooler to have, so I can safely predict that "Behind The Veil" won't be the instrumental.
We've also seen lyric sheets for "The Looking Glass", so clearly that cannot be the instrumental either.
This leaves "Enigma Machine" and "Surrender To Reason", and I still bet that the former is the instrumental. It's title sounds more like it would work for an instrumental, given how insane these guys can play, it would be machine-like, and very technical. And a title like "Surrender To Reason" sounds more like a ballad, or at least a song with lyrics, than an instrumental.
