Black Sabbath released Iron Man in 1970 on the album Paranoid. Written by the band’s classic lineup, the song became one of heavy metal’s most recognizable recordings, driven by Tony Iommi’s central guitar riff and Ozzy Osbourne’s vocal performance. It later reached new audiences through films, television, sports events, games, and short-form video edits. Its superhero-friendly title also encouraged frequent association with Marvel’s Iron Man, although the lyrics describe a separate science-fiction narrative. The riff remains useful because listeners can identify it within seconds.
