I have to agree.
I am a HUGE Dream Theater fan, and have seen them EVERY time they have come through KC since Images and Words.
The sound was horrendous on April 9, 2014.
LaBrie was WAY too loud. The speakers seemed to be cranked to the MAX, and distortion was prevalent. The distortion was so bad that it was very difficult to hear anything coming from Myung, or Rudess, except for a subwoofer rumble. I had a hard time hearing details of Mangini's performance, unless he was the only one playing.
Don't get me wrong, I could hear well enough to completely appreciate the normal Dream Theater musical brilliance, but it was far from the better/best shows sound-wise I have heard from them.
