Anywhere near downtown Tulsa Sunday night it was clear that something major was going on at a concert venue near you. While the majority of the downtown traffic aligned for the sold out Katy Perry show at the BOK Center, Cain’s Ballroom had a sold out show of their own. Winning the traffic battle to reach Cain’s before the show it seemed the audience was just as much looking forward to seeing The Walkmen as they were the Fleet Foxes.
