Deryck Whibley of Sum 41 talked with GQ in a wide ranging interview:

It’s partly the same reason that, last August, Whibley decided to sell the rights to Sum 41’s entire publishing-and-recorded-music catalog to an investment fund called Harbourview Equity Partners for an undisclosed sum. For a long time, despite several approaches, “I was so against selling it,” he says. “My songs are my babies, and I didn’t need the money.”

Then he started to question what he was so afraid of losing. He decided to conduct a thought experiment: “I told myself, Okay, I’m going to wake up tomorrow and act like I’ve sold it. What does that feel like? I woke up scared shitless. I had no songs. And I felt so excited and I picked up a guitar just naturally. Almost right away I wrote “Landmines”. And then I wrote another one, and then another one, and then I had another riff, and it was like, holy shit.” Letting go of his songs—much in the way he’s letting go of the band entirely now—unlocked a vital hunger inside of Whibley. “I felt the way I did when I first got signed. I felt the pressure and the need to create something.”

What he wound up creating was Heaven :x: Hell, a double album slated for early 2024 that should serve as the perfect capstone to the band’s two distinct eras: one side entirely All Killer–style pop-punk jams, the other full of the scorching metal headbangers they’ve favored lately. “I feel like there’s no other band in our genre that can just so easily pull this off,” Whibley says. “We have our own lane. It’s a great last record.”
