The song was first played on The Zane Lowe rock show on 19 March and the official music video was uploaded to the band's MySpace page shortly after.
Davies has mentioned that it is a concept album: David is a Fisherman who is captain of a boat that regularly trawls the deep waters, he comes from a small fishing town on the coast where his wife Eleanor and daughter Isabelle await his return, but a huge storm is quickly approaching it hits the town and then batters David's boat and leaves him shipwrecked in the middle of the ocean as the only survivor.
He spends days adrift going crazy and delirious wondering if he will ever see his family again, meanwhile the towns people fear that the fishermen are all dead, the coast guards rescue attempts have failed to recover any survivors.
He is scared of the waters and the colossal waves and power that killed his crew but he decides that doing nothing to get back to Eleanor and Isabelle is a cowardly way out so he decides to build a small raft and brave the elements once again, this time he is found by a lifeboat and reunited with his family.
Basically, Cast Away meets The Perfect Storm, it has a lot to do with my own personal fears of the ocean and coming to terms with that through the story.
