Dave Grohl has released outtake footage from Foo Fighters’ 2014 documentary series Sonic Highways, where he’s seen reacting negatively to old demos recorded by the band.

The scenes were shot while Grohl made an eight-part TV show to accompany the eight-track album of the same name, which featured Foo Fighters recording each song in a different U.S. city while exploring the location’s musical heritage.

Grohl is seen in Laundry Room Studios in Seattle, catching up with old friend and producer Barrett Jones, who has the archive recordings. In between reminiscences about their lifelong friendship, their age difference and working history, Grohl asks Jones to let him listen to numbers called “Watered It Down” and “Slackers Password.” He’s clearly unhappy with what he hears, labelling one sequence: “Interesting and weird” but also saying, “it reminds me of our living room.”

These are the third and fourth early songs by Grohl that Jones has uploaded. Earlier this year, we saw Grohl mock "Gods Look Down" and "Rent (Jerky Boys)."

Foo Fighters last month announced their ninth album, Concrete And Gold, would be released on September 16. Grohl said the band had decided to work with producer Greg Kurstin, best known for his work with Adele, Pink and others, because of the crossover opportunities.

“I think maybe Greg is the guy because he’s never made a heavy rock record before, and we’ve never worked with a pop producer,” Grohl reported, adding that they’d created an amalgam of “our noise and Greg’s big brain, his sophisticated arrangements and composition.”

The band commence a North American tour at Cal Jam in San Bernadino, Calif. on Oct. 7, and end the road trip on December 12 in Salt Lake City. Most tickets go on general sale on July 29.
