After much thought, my pick is :

A DRAMATIC TURN OF EVENTS -- Dream Theater

I know, I know..............many on this board are unimpressed, and some will rebut even never hearing a note of this CD, however, Mangini has brought something new to this group and this release has some spectacular composition...........the best of which is track # 4, THIS IS THE LIFE.........beautiful stuff.
Maybe the band is growing maturity and will mellow a bit -- this could be the new beginning.
