Overview: Heavy: The Story of Metal is a four-part documentary special that aired on VH1 in 2006. The series focuses on the origins, subgenres, and the bands of heavy metal music, paying close attention to influential bands like Black Sabbath, Led Zeppelin, Judas Priest, and Iron Maiden, who helped to define heavy metal in its early years. Other bands on the program include, Alice Cooper, Kiss, AC/DC, Van Halen, Def Leppard, Quiet Riot, Mötley Crüe, Megadeth, Metallica, Anthrax, Guns N' Roses, and Marilyn Manson.

In Canada, the documentary aired on MuchMoreMusic and on C4 in New Zealand. It is not available on DVD or video.
