Foo Fighters have given fans more clues as to what their mystery countdown on their website may be about.

The website has the band’s logo in a crest and the countdown will end on November 23, leading fans speculating about a big upcoming announcement.

Some fans have compared the crest to that of the Route 66 sign, suggesting that a second season of Sonic Highways might be coming. Others have thought it may be the date that Dave Grohl’s leg cast is removed.

Earlier this year Dave Grohl confirmed that there would be a second series of ‘Sonic Highways’.
