Panic! at the Disco brought their "Pray For The Wicked" tour to Milwaukee on Sunday.

And despite temperatures in the single digits, plenty of fans packed out the Fiserv Forum to see Brendon Urie and Co. turn up the heat—quite literally, as they brought flame projectors and Urie himself even stripped out of his shiny, Vegas-ready jacket to perform shirtless, showcasing not only his vocal prowess but a lean physique as well.

Not only was the massive show a welcome treat for a part of the country forced to spend much more time indoors lately (as of this writing, it's -10 degrees in Milwaukee), but it comes as Panic! has been experiencing perhaps their best year yet, 15 years into their run as a band.

They've had hit after hit on the radio and they've still got a mammoth number of dates on this tour, with upcoming stops in Cleveland, Kansas City, Austin, Los Angeles and more, all before heading to Europe and the U.K., with festival dates also in the mix.

Panic! at the Disco clearly isn't slowing down anytime soon. And that's definitely a good thing.
