I have played Mega Man 2. Several times. Usually I've played Mega Man 2 alone with the TV turned up so all my neighbors can listen and say to themselves, "He's playing Mega Man 2 again. Awesome!" Never once have I had my session of Mega Man 2 accompanied by a band. This guy has done it.
MAGFest is an annual event that combines the world of video games with the world of music. When these worlds collide, you get the cosmic greatness above. Excellent job, Bit Brigade. You've destroyed us all... and it's glorious.
And thumbs up to the player for not dying and being super-efficient.
