I can't find decent video, but as I watched UNC in the tunnel getting ready to come out vs FAMU..Big Bell Rings, 4 times, crowd goes ape shhhiiittt.
Below is how the entrance is accomplished...
The Stadium speaker system ignites the crowd with a guitar solo from “Hark the Sound.”
The video board shows the Bell Tower, and the bells are rung slowly and loudly.
A hard-hitting, fast-paced video montage lasts 30 to 40 seconds. Video is great plays ,moments, stars from the past with current players flexing etc.
The bell tower at UNC is legendary.
MY POINT IS USING WHAT YOU HAVE TO CREATE ATMOSPHERE DOESNT COST ANYTHING BUT PLANNING AND EXECUTION
