Concrete and Gold is the newest chapter in 11 Grammy award winning rock-gods Foo Fighters career. Set for release on September 15th, the aptly named album is the result of the bands first ever collaboration with producer Greg Kurstin (Adele, Sia).

After becoming obsessed with Kurstin’s band The Bird & The Bee, Dave Grohl developed the unlikely alliance. This will be the band’s first time working with a pop producer who, in turn, has never produced a rock record. Recorded in secret sessions at Hollywoods EastWest studios it’s blueprint has been described as “Motorheads version of Sgt. Peppers Lonely Hearts Club”. This is set to be Foo Fighter’s most ambitious album yet and its not hard to see why. First release and summer jam ‘Run’ has already given us a taste of the sweet sour, ‘concrete and gold’ sound produced from this marriage of genres.

The next challenge the band face is how to celebrate such an achievement. Hosting what they describe as the ultimate “backyard party for 50,000 people” on October 17th. ‘Cal Jam 17’ (in spirit of the original California Jam) will be 12 hours of non-stop and totally live rock music. Priding themselves on their choice of ‘unfuckwithable’ line-up, bands from across the glob will be joining in the celebrations: Queens of the Stone Age, Liam Gallagher, Cage the Elephant, The Kills and Royal Blood, to name just a few.
