"Electric Eye" is a song by British heavy metal band Judas Priest, from their 1982 album Screaming for Vengeance, and released as a single later that year. It has become a staple at concerts, usually played as the first song.
"Electric Eye" is featured in Grand Theft Auto: Vice City Stories for PSP and PlayStation 2. It is also a playable track in Guitar Hero Encore: Rocks the 80s as a master track, including "The Hellion", and it also appears on Guitar Hero Smash Hits. Additionally, it is available for download on Rock Band, as of April 22, 2009, as part of the entire Screaming for Vengeance album download, or as a single song. It was also featured in the second trailer for the video game Brütal Legend. 
This song is referenced in the movie Tenacious D in The Pick of Destiny, in the song "Break in-City (Storm the Gate!)".
"Electric Eye" is an allusion to the book Nineteen Eighty-Four by George Orwell, in the use of the name of the pseudo-omniscient satellite that watches over the community at all times. In thisdystopia, the form of government, Ingsoc (Newspeak for English Socialism), is utterly totalitarian, and if citizens are caught rebelling in any manner, they "disappear". The song has been called "prescient" for its depiction of a modern surveillance state.
The song is usually played right after the album's intro "The Hellion" during live concerts. An exception is during the tour for the album Demolition, in which the band went straight into "Electric Eye" with no intro, which can be heard on their live album Live in London. "The Hellion" was recently used for a commercial for the 2011 Honda Odyssey.
The song was played live at the 2011 Revolver Magazine Golden God Awards show by Duff McKagan's Loaded, with vocals by Slipknot and Stone Sour's Corey Taylor and guitar by The Sex Pistols' Steve Jones.
"Electric Eye" was covered by the metalcore band As I Lay Dying from the compilation Decas, and was released as a single. The band made a music video for the song and was first available to stream via Noisecreep on October 3, 2011.
