Saw The 1975 here in May. First off, love the location right on State Street with an awesome view of the Capitol building. The show was on a Saturday night, but was still able to find parking available in a garage just a few blocks away which was nice.
The venue is very nice. They had a pretty good system in which they handed out different wristbands for who can and can't drink, whether they're underage or designated driver. They handed those out while you waited to get in to the building. I chose to watch the show in the balcony and wasn't disappointed. The venue is beautiful, and you have an awesome view of everything from there. The show was sold out, yet there was still plenty of space open in the balcony, so you could move around and find the perfect spot without any trouble. I could also feel a gentle breeze of what I assume was a ventilation system, which makes for an added bonus. Most importantly, the sound in the venue is great. Definitely a great place to see some live music.
