All the bands were awesome, but the sound and lightning sucked. You could barely hear the vocalists, couldn't understand them at all, because the balance of the volume was so off. The instruments were booming, the vocalists were almost non-existent in the background of that sound. That's how it was for all 4 bands. The lights were poorly setup, and they kept beaming the audience in the eyes and blinding us. If that wasn't enough, the ventilation was sub-par, and they kept puming out nitrogen to cool everyone off (a practice that has been known to kill people at concerts).
I would love to see Lacuna Coil again at a better venue, but I will never attend a concert at Summit ever again. You couldn't pay me to go to Summit.
