The energy was great, and the fans were excited. The best portion was when everyone sang the tune of Super Mario Bros. The music was nice, the video was nice, but I think your local venue, and your local choir and orchestra will have a large effect on the show.
The music felt so small, I remarked to my wife from the second he started playing the guitar that someone should tell him it wasn't plugged in. It took me a while to realize it was plugged in, just a whisper. I was in the front row, I could hear the strings, I could hear the pick, but there was no sound. The orchestra sounded similarly, off, or not there at all. The choir connected well during the FFVII song which was awesome.
It felt like we were listening to a CD play the music, and then the instruments try and match up to that music. It just felt off. At one point during Skyrim it was painfully obvious their audio was way off. You could hear the music playing and then they added a vocal roar from the game. That roar was 10x the volume of everything else and was very much out of place.
In the second half both projectors became out of focus and were never fixed. So I don't know if this is Video Games Live, or Cedar Park Center, or a bit of both.
I guess that was the big letdown for me, I couldn't feel the music, and I wouldn't have had the same experience watching the production on YouTube at home, maybe better because I could have turned the volume up.
