The band Kings of Leon have released a new trailer for their upcoming album Walls, their first in nearly three years. So far, we don’t know too much about the new record other than the fact it will be a very “personal” album, it drops on Oct. 9, it’s being produced by producer Markus Dravs (known for his work with Mumford & Sons, Arcade Fire, Coldplay, Florence and the Machine) and, oh yeah, its artwork involves extremely creepy doll heads.
