I've enjoyed the whole interview and it's another way to raise my expectations.
The part where they mentioned that in the past the recordlabel seems so point out who would be mixing and producing the album and the way they feel being released of that... and be able to pick Timmy and Andy... I feel familiar with that. Because - to me - that's what I think (beside the overwhelming positiveness that Mangini brings all along) is what I like so much 'bout Dream Theater nowadays. Not being forced in whichever direction and totally able to make the music they want. And very nice to see the many shoutouts on the producers by any of the members.
Also I love the part where they expelled to make an epic, they first get rid of all boundaries there could be and starting crafting until there's evolving something epic-worthy. I am so much looking forward to this track. Because even the least of the epics in my opinion (In the Presence of Enemies) is so beautiful and whenever I listen to it, I realize it's been way too long since the last time I did.
I really liked the way Petrucci mentioned the vocal power of LaBrie, "building up places where James can do a beautiful solo where he digs everyone in..." or some like that. Nice to see they still admire LaBrie for who he is and what he brings. My sympathie for LaBrie has grown skyhigh over the years, where I first didn't like his voice that much. I've learned to appreciate the beauty of it.
And last but not least, brilliant so see Myung building up an crescendo with all the layers involved, like the headspace and lifting it off by saying, "it's Rush-inspired..."
sidenote, since English isn't my familiar language, sorry if it lacks or cracks here and there...
