Apparently working with Josh Homme made the Arctic Monkeys become a dark, muscular behemoth--here's a video of the band playing a new song, titled "Crying Lightning," at Big Day Out that is a murky, low-tuned guitar-led track that equates a relationship with a war (pretty standard Alex Turner).

"Crying Lightning" is set for inclusion on Arctic Monkeys as of yet untitled thrid LP, due out sometime in 2009. [Stereogum]
