The above video shows the end of the night, when audience members and performers gather on stage to air guitar to “Freebird”–an air guitar tradition.
This is the compulsory round performance by Windhammer. During this round, performers must spontaneously come up with a routine to a surprise song on stage. They hear these songs once before having to come on stage and perform to them. Instead of performing to the entire song, he chose to remain stoic in the first few measures, which heightened the anticipation of his first dramatic stroke on the air guitar.
Below you can see the halftime show. You can see Justin “Nordic Thunder” Howard perform solo, after which he is joined by three others.
