MUMBAI: “I wanted it to be the biggest sounding Foo Fighters record ever. To make a gigantic rock record, but with Greg Kurstin’s sense of melody and arrangement, Motorhead’s version of Sgt. Pepper or something like that,” says Dave Grohl.

Foo Fighters’ ninth epic, the aptly-titled ‘Concrete and Gold’, will be out on 15 September worldwide on Roswell Records / RCA Records.

Just as Foo Fighters’ anthem of the summer ‘Run’ opens as a dreamy, slow burner then quickly turns heavy as thunder with its huge triumphant chorus. ‘Concrete And Gold’ marries some of the most insanely heavy FF riffs ever with lush harmonic complexities courtesy of a first time team-up with producer Greg Kurstin (Adele, Sia, Pink).

This unlikely alliance came through a bizarre sequence of surprise musical obsessions and chance encounters. Listening to the radio during a drive roughly four years ago, Grohl first heard ‘Again and Again’ by Kurstin’s band The Bird and The Bee-“It blew my mind. It was so much more sophisticated than anything I’d ever heard and I became obsessed.”

While Foo Fighters recorded and released ‘Sonic Highways’, broke some bones and packed stadiums and arenas on one of the top five grossing tours of 2015, and gifted fans with the St. Cecilia EP, “Greg was becoming one of the biggest producers in the world,” Grohl recalls.

With the writing and recording of the next Foo Fighters album on the horizon, Grohl was eager as always to find fresh challenges for the band: “So I think maybe Greg is the guy that we ask to be our producer because he’s never made a heavy rock record before and we’ve never worked with a pop producer.” Darrel Thorp (Beck, Radiohead) was soon enlisted to mix and engineer. This collective conceived a blueprint of the new record as “Motorhead’s version of Sgt. Pepper or something like that,” secretly booking into Hollywood’s esteemed EastWest studios to consummate this marriage of extremes or as Grohl puts it: “Our noise and Greg’s big brain and all of his sophisticated arrangements and composition.”

What came to Grohl in that vision will become reality 7 October when Foo Fighters’ Cal Jam 17 takes over Glen Helen Regional Park in San Bernardino, CA. In addition to being Foo Fighters’ biggest ever one-day U.S. headline, in the spirit of the original California Jam, this daylong marathon of eating, drinking and rocking features an absolutely unf**kwithable lineup: Queens of the Stone Age, Cage The Elephant, Liam Gallagher, The Kills, Royal Blood, Japandroids, Wolf Alice, Bob Mould, The Struts, Bully, Circa Waves, Babes in Toyland, Adia Victoria, Fireball Ministry, The Obsessed, Pinky Pinky, Starcrawler, White Reaper and in addition to 12 hours of rock and roll good times, Cal Jam 17 offers camping, carnival rides, a water park, attractions, a mobile recording studio and so much more. On Friday night, 6 October, campers will also experience the world’s best Go-Go band Big Tony and Trouble Funk, an outdoor movie theater and many other surprises.
