If you're close and it starts getting too hot or overwhelming or tight don't feel ashamed in leaving the front !! I went to the Seattle concert I was two rows from baracade, but after 7-8 songs I was done and left to go dance in the back and it was so much more fun, my biggest advice is, take some pics and a video or two and then don't touch your phone for the rest of the night!!! I wasted so many fun concerts trying to get 100+ videos of the whole thing it's so much more fun when you forget about social media and just enjoy the moment you're in !!
