If you thought that trailers were just for movies, think again. Earlier today, The Killers released an official teaser for their upcoming album 'Battle Born'. There's still no exact release date but we can expect the follow-up to 2008's 'Day & Age' to drop sometime in "Fall 2012". Are you excited yet? You can watch the trailer below and if you can't wait until the autumn to hear their "difficult fourth record", new "heavier" material is expected to debut live during The Killers' worldwide festival appearances.
