Panic! at the Disco entered the music scene 13 years ago and have long since solidified their place in both the mainstream and alternative realms. Following a well-earned Grammy nomination this year, Panic! embarked on the Death of a Bachelor Tour across the U.S. to finally bring their most recent album into arenas. The band made their Madison Square Garden headlining debut last night and kicked off the sold out show with a surprise appearance from Stranger Things‘ Noah Schnapp, who sang “LA Devotee” with the rock band. During “Girls/Girls/Boys”, fans in the audience held up colorful hearts illuminated by their iPhone flashlights and creating a rainbow pride flag across the floor of the arena – earning a genuine moment of emotion from frontman Brendon Urie. It was a special night for a special band. Check out some photos from the show!
