Queens Of The Stone Age frontman Homme and Pop wrote and recorded the album in secret, roping in Arctic Monkeys drummer Matt Helders and QOTSA man Dean Fertita for sessions at Homme's Joshua Tree and Pink Duck studios. The touring group will be completed by QOTSA's Troy Van Leeuwen and Chavez bassist Matt Sweeney.

The partnership started with a text from Pop to Homme which read, "Hey, it would be great if we got together and maybe write something sometime - Iggy."

Homme tells the New York Times: "He is the last one of the one-of-a-kinds. This is a much deserved victory lap for a man who's not sure if he won. But he did. He may have tunneled underground for lots of that, but he still got to the destination."

The pair shared ideas via post before agreeing to hit the studio to record Pop's first release since 2013's Ready To Die by The Stooges. Homme adds that working on the record helped him deal with the Paris terror attacks that saw 89 people killed at the Bataclan venue where Eagles Of Death Metal were performing on November 13 last year.

He says: "I wasn't there by a stroke of fate. I guess it was my fate to be home and to bring them home. Bad things are like a sunset, they dissipate over time. But this is a long sunset. My dearest friends - how will they un-see that?
