What a great new Dream Theater record! When I get home from work, all I really want is to listen to this record without doing anything else. ADTOE was disappointing to me, so that's a great feeling to have. The record + tour also didn't convince me that much yet, and I still very much missed Mike Portnoy in the band.
All I can say now is: Mangini stepped up to the plate, is musically integrated and just delivers an all around amazing performance. Not my favorite drum sounds, but at least it's got some weight to it that was missing on A Dramatic Turn of Events.
I'll always 'miss' Portnoy, especially when listening to Awake, Falling Into Infinity or Six Degrees of Inner Turbulence, but the undeniable result this time is (IMO) that Dream Theater is their strongest album since Train of Thought. And it's with Mangini.
