Asked if there was anything he wished DREAM THEATER had done differently in the way they went about finding a replacement for original DREAM THEATER drummer Mike Portnoy in 2010, DREAM THEATER guitarist John Petrucci told "The Classic Metal Show": "There's not many situations in life where you can say you wouldn't have done anything differently, but this is one of 'em. I think, looking back, I wouldn't have done anything differently."
He continued: "Mike Mangini really helped us to get through a major bandmember change, and in a way, that was probably as smooth as any bandmember change could have gone. The way that he came in, his personality, his skills as a drummer, his background, his history… it clicked to the point where it was, like, if we would have met Mike [Mangini] twenty years ago, we would have been playing with this guy. If I would have grown up with him, I would have been friends with him jamming. And that's rare. It's rare to do that one time around."
Petrucci added: "You know so many musicians in bands that are having trouble finding people to play with, and who click, and so the fact that this happened with Mike [Mangini], it's really just amazing to us. And since he's been in the band, we've done [three] albums, [several] world tours and, thankfully, have had a lot of success with it, and a lot of support from our fans through all of it. And, again, I wouldn't have done anything differently. It's really amazing."
