The Milwaukee Admirals had the Dropkick Murphys perform after their hockey game. It was a huge success. Would the Milwaukee Bucks do anything like that? Probably not.
The NBA has so much more control over what teams do as far as promotions. A minor league hockey team is not nearly as high profile as the NBA. With that being said, would Bucks Tickets sell at a faster pace if the NBA allowed the Bradley Center management to have a live band perform just after the game?
The Bucks are a small market team. Revenue streams of any kind should be explored. Not to mention, you could draw new Bucks fans if you match up the right bands to play live. Some say that it's not needed. If you ever go to an early season Bucks game, you might disagree. The seats are empty in the upper levels for games on weeknights. Why not have a band play after the game.
