"Demons" is a song by English big beat musician Fatboy Slim, featuring Grammy Award-winning American R&B-soul singer Macy Gray.

It contains elements of Bill Withers' 1973 song "I Can't Write Left-Handed".

The gospel group The Blind Boys of Alabama covered the song on their 2005 album Atom Bomb.

The DVD single includes the "Demons" music video (with multiple angles), a "making-of" featuring an interview with Macy Gray, and a TV spot for the album.

The video portrays a miniature man trying to rescue a woman being caught in the menacing metallic jaws of a piano in a cathedral.
