If being close to the stage is most important to you, you'll want to spend more money to be in a lower level, or at least on the side of the stage. But if you care about comfort, these seats are pretty perfect.
They're on the right side of the section, so you're nearly looking eye-to-eye with the performer. The height is actually pretty cool, as you can see a lot of what's going on -- including sick glow-stick action in the lower levels. In addition, being on the aisle three rows from the concourse entrance means getting into and out of the seats is a breeze. The aisle gives plenty of room to toe-tap with the music, and I literally was able to get a beer in between songs because it takes about 30 seconds when there are no lines (one of the premium beer stands is right outside this section).
Overall, you do spend a lot of time watching the show on the screens -- and the sound at the United Center for a concert is unforgivable -- but these are some of the best cheap concert tickets you can find at the UC.
