Grohl also recently teased that the record is “unlike anything we’ve ever done”.
But the frontman has now admitted that he is apprehensive about people hearing it.
”I’ve never entered into the album process thinking, ‘We’re the greatest, most amazing, biggest band in the world’,” Grohl told Mojo.
”You might convince yourself of that when you’re in a room listening to shit you’ve just recorded. But the second you hit play in front of a roomful of strangers, you turn into a six-year-old kid with his pants down at school. Absolutely. You’re just [fearful].”
Drummer Taylor Hawkins also opened up about the new direction the band are taking.
“We’ve kind of become the AC/DC of post-grunge or whatever. So, the reaction is going to be interesting. It’s the most pop fantastic album we’ve ever made,” he said.
”But I had a hard time making this record because I was like Roger Taylor in the Queen movie. ‘We’re resorting to drum loops?’ I almost feel like Dave likes chaos a little bit then likes to control it.”
The rock giants announced plans last month to celebrate the milestone by touring the same stops as their first US tour back in 1995.
