Prior to the opener against New Orleans, while all of the NBC fans were milling about for the music shows...for the life of me... I can't even remember who in the sam hell they were ... my son and I grabbed a seat in Curly's for a couple of cocktails right by the windows. You could SEE the back of the stage and all of the people that were in the stadium parking lot, ok?
Could not hear anything from that stage inside Curly's...no rumbling bass ... no drum solos ... nothing. Of course the show outside was on all of the TV's but aside from that...nothing from the exterior.
So, if I were a betting man, if you're sitting inside of Curly's during the game (and yes, you'd need a ticket to get inside the Atrium on gameday - you can't even get into the ProShop without a ticket on gameday), you wouldn't be able to hear the crowd noise.
