The Denver concert was amazing. The band did great, the lighting was impressive, and I have to say there are definite advantages to the notorious screen. It's so vivid, and the dark regions stay dark (instead of picking up stray projector light or reflections from the front). Photos of it really don't do the set justice. When the colored spotlight beams come down from the top, they end up being visible behind the screen and in front of it on the smoke in the air, so it sometimes looks like it's blending with the LED panel. The line art is fully RGB and coordinates with the vocaloids as well. There didn't really seem to be anywhere that would have a bad angle, except for extreme sides near the very front.
The crowd was great, and I had fun in the lines and hanging out in the bar areas inside the venue before going up to the balcony for the reserved seats. A ton of cosplayers, and people posing Miku plushies and figures for photos.
Didn't end up making it in time for light sticks, but hung out in an adjacent brew pub until the line for entry started, and someone gave us some chemical glowsticks.
Edit: I do strongly advise concert earplugs (Etymotic or similar) for anyone going, having experienced it and taken decibel readings with my Apple Watch. It was hitting 93dB a lot and triggering warnings on my watch, and you can feel the bass frequencies heavily in your chest. Protect your hearing if you like music!
