said:Rudess, who stays busy with solo records and a series of best-selling instrument apps under his Morphwiz brand, was extremely happy with the band's choice of Mangini.
"We saw some great players obviously, but Mike came in totally ready, willing, and able to do this job. For him, the universe had aligned: this was his future as well as ours. We knew it and he knew it. His playing, his performance energy -- from the very beginning it became clear to us that was committed to this to extremely serious concept known as Dream Theater."
said:"It was interesting to write music without a drummer in the room," Rudess mused. "Different for us and very unique. Still, we had the core compositional team in place. And this whole experience of dealing with Mike's exit has been a huge challenge for the band. But we wanted to pull the positive from all the change and use this as an opportunity to challenge ourselves to produce some really powerful music."
