"War Pigs" is an anti-war protest song by British heavy metal rockers Black Sabbath from their 1971 album, Paranoid. The song talks about war and the absurdities of those who make war without regard to the powerless people who are sent to die.
Originally intended to be the title-track, the name of the album was changed to Paranoid, as that song was released as the single. It is one of Black Sabbath's most popular songs, and is still played on Classic Rock stations regularly. The riff, as with most Sabbath songs, is powerful and memorable, as are the eerie verses, which feature Ousborne singing alone and punctuated at every line by a guitar lick.
It is very likely the riff inspired Metallica's "Master of Puppets" main riff.
