To celebrate the release of brand new track 11 Minutes, which also features blink-182's Travis Barker, Halsey and Yungblud will host a surprise Valentine's Day pop-up in Sydney TODAY.

With Yungblud already touring throughout Australia, US singer Halsey will join him today at The Commune in Waterloo from midday. 

Check out 11 Minutes below.

The song tells the story of a perfect tragedy that reflects modern love within our society," Yungblud said.

"We are so distracted and focused on what’s next, we can fail to see what is actually in front of us. We don’t realise how much we need something until it’s taken away from us.” 

He continued, "Working with Halsey and Travis was a fucking dream – at the end of the day we’re all rock kids.

"We grew up with a mutual adoration for the genre so it completely makes sense that we would come together and try to modernise it.”
