The countdown clock on the Foo Fighters' homepage isn't just readied for Halloween. On the contrary - it's set for 24 days from now, hitting zero at Midnight on the 20th of November. At that time, the band headed by Dave Growl could well release a new season of the HBO-centric documentary series Sonic Highways. The logo plate on the website indicates as much. On the other hand, this could be a place for the launch of an EP - the band recently recorded five songs in Austin, after all.
