Was going to post X Japan if nobody else did. I saw them in 2010 on what happened to be Toshi's birthday, so he declared that the concert was his birthday party and had people going around the crowd waiting to get in and handing out pizza slices to everyone before the show. One of the best concert experiences I've ever had. The concert itself was also fantastic, I've never been happier to be almost deaf on the way home from a show.
