What's the best concert you've ever been to?

I just went to an All Time Low/Waterparks/SWMRS/Wrecks show and I had a really great time (I went up to Awsten Knight as he was hanging near the merch table, as I was the first one to recognize him, and I went "HI MOM" and hugged him really tightly, plus I screamed so loud at the show that my voice is completely gone) but I was thinking earlier that I wanna hear stories from other concerts I've never been to and will never get to go to, maybe leave me a comment?
