Band of Horses are an American indie rock band formed in 2004 in Seattle by Ben Bridwell and Mat Brooke. This is the first single from their second full-length album, Cease to Begin. It became the group's first charting single in the United States, peaking at #34 on Billboard Modern Rock Tracks.
This song was #93 on Rolling Stone's list of the 100 Best Songs of 2007.
Bridwell told The NME April 24, 2010 that this song was inspired by his feelings of paranoia. "I suffer from paranoia really badly," he said." And the thing that inspires me most is, once I get into that horrible isolated area, I think I'm being watched." He added: "I've written songs that are based specifically on that feeling. 'Is There A Ghost' was based on an ice-maker in my house that was freaking me out."
The song featured in an episode of the Fox television show Fringe, which aired on May 6, 2010 in the US. In the episode titled Northwest Passage, the character Peter Bishop is shown listening to the song in his motel room after it was put on a CD for him by another character earlier on.
