Urie made his way through songs spanning the band's five-album catalogue from their nearly 14 years in the business, including popular classics I Write Sins Not Tragedies, Nine in the Afternoon, Miss Jackson and more.
Fans pressed against the barrier in a crush so intense security was having to distribute water half way through the opening act, and the first fan had to be pulled from the crowd before Panic! even took to the stage.
Fans continued to be pulled out of the crowd throughout the show, some walking away crying, others having to be carried out.
But Urie raged on, dancing on the points of his toes, swinging his arms around wildly and back flipping from the drum platform.
And the man can sing. His rendition of Queen's Bohemian Rhapsody brought the house down as he hit all of Freddie Mercury's high notes and continued to nail falsettos and screams throughout the set.
He also knows his audience; taking their gifts with him on stage, dabbing, referencing the popular "cash me outside" meme, declaring his love for them and welcoming their adoration.
He didn't leave the stage before an encore, opting to just throw in an extra song instead of wasting time going offstage, and - fittingly - rounded out the set with Victorious.
Urie's come a long way from the early Panic! days, embracing a pop/soul/jazz/funk sound and boasting vocal skills leagues apart from where he started.
