Green Day have that special sauce down when it comes to their shows that always sets them apart, and seeing them at Hella Mega alongside other bands that are just good in a typical way at putting on a show really highlights that difference. Everything got kicked up a notch when they came out and it has everything to do with the way Billie connects with the audience both individually with eye contact, taking flags, wearing hats, sunglasses, etc. and inviting fans up and as a group with commands throughout the show to participate making it interactive. Plus his energy is off the charts.
