Foo Fighters treasure hunt reveals mysterious artwork

Composite image pictures eight US cities and number '8' in centre

Foo Fighters fans have assembled an image which is believed to be either the cover of their next album or an image to promote their forthcoming HBO TV series Sonic Highways.

The band, who promised to announce some “big news” next Monday began posting geographical coordinates to their social media channels on August 4.

At each location – thought to be the US cities where the band recorded – a poster could be found which, when pieced together, make a larger image with a figure eight in the centre. The as-yet-unnamed album will be Foo Fighters’ eighth album.

The image contains landmarks relating to eight cities in the USA: Seattle, Chicago, New York, Hollywood, Washington, DC, Austin, New Orleans and Nashville.

Described as “epic” by producer Butch Vig, the new album is due for release in November and will be accompanied by mini series Sonic Highways, which will document the recording progress. Dave Grohl will operate as director on the project, following his Sound City documentary of 2013.

Meanwhile, Foo Fighters are to return to the UK stage at the closing concert for the Invictus Games in September.

The event takes place at London’s Queen Elizabeth Olympic Park on September 14, and sees Dave Grohl and co top a line-up that also includes Kaiser Chiefs, Ellie Goulding, Ryan Adams, The Vamps, Rizzle Kicks, James Blunt, Diversity and Military Wives Choirs. The 26,000-capacity outdoor concert will take place on the south lawn of Queen Elizabeth Olympic Park from 5pm to 10pm and highlights will be broadcast by the BBC.
