Pre-game question "The Approaching Storm"

I usually make it to my seats about 5 mins before kickoff. For those of you that are there early can you tell me when I would need to get to my seat if I want to see "The Approaching Storm" perform? I have a son who has never seen a HBUC Band performance, and would like him to see as much as possible. Stars are aligned today to I can make it earlier. Trying to figure out when to leave.
