Under the Glass moon

It was starting to be a heavy drive back home from office today.

At 11:30 PM, there was not a soul on the lonely Mysore road. I was tired, the air was nippy. So I rolled up my windows and settled into a cozy drive back, with the song - 'Under the Glass Moon' playing inside.
I am literally in awe of the band Dream Theater. I started out with the more melodic 'Take away my pain'. I love huddling up and listening to Change of Seasons, Falling into Infinity, or Octavarium.

But this song...
What an awesome opening, stunning riffs, and what a solo...Petrucci is a master.
Still, I can't get this nagging feeling out of my mind...Whenever I listen to it, I feel the vocals could have been better. Was LaBrie a right fit for the band?
