The bashed-in heat lamp on the Downtown venue’s back patio told the post-show story early Sunday: Metz’s first Vegas visit had been cold and crazy.

Even before Toronto’s it trio hit the stage, wildness was afoot, from the stage-diver who nearly met his demise leaping into a sparse Caravels crowd to a madhouse moshpit that threatened to take down all three heat towers while Douglas and the Furs played second.

By comparison, the reaction to Metz’s headlining set felt kinda tame … initially. The Sub Pop noise-rockers (think: Albini crossed with Dischord) sounded best at their most unhinged—Alex Edkins’ vocals screeching, Chris Slorach’s bass consuming space in throbbing waves, Hayden Menzies’ drumsticks blurring the background—and as they ratcheted up their intensity, so did the crowd, until the scene could have been confused for a riot.

“Thanks so much for moving around. This is our first time in Las Vegas, and it’s f*cking amazing,” Edkins praised. Trust us, Alex, you stopped by on a very unusual night.
