Hmmm..... why have I never seen this thread before??
Anyway, I have DEFINITELY experienced moshing at a Creed concert. The one and only Creed concert I've been to was March 2002, and where I was, it was quite rowdy. During My Sacrifice in the encore, the crowd just went off!!! There were about 4 crowd surfers passing over my head, and plenty of shoving and jumping around!
