The Foo Fighters will play their first show in over a year at Mexico City's Foro Sol Stadium on December 13.
They are apparently working hard to get ready.
Front-man Dave Grohl posted a picture of a blood splattered guitar along with blood soaked picks to the band's Facebook page.
The band is doing more than just gearing up for their first concert since going on hiatus in September of 2012. Guitarist Chris Shiflett recently told Rolling Stone that the band has been rehearsing a new album and plans on recording it, "at the beginning of next year."
