My last experience with a stadium was several years ago, 2006 or so. I managed to get a 6-pack through security by approaching security without it and having my back checked, then realizing I had to go to will-call (outside of security). On the way back in they recognized me and waved me through security with my ticket and "already checked" bag (now with beer). No idea how reproducible that is, and it was during a sports event instead of a concert (I think both probably contract the same venue security though?)
