Fronted by Ozzy Osbourne and led by Tony Iommi’s masterful guitar playing, Black Sabbath’s hits like “Paranoid,” “War Pigs,” and “Iron Man” remain essential listening for any metal fan. Their sinister themes, heavy distortion, and slow, menacing tempos set the template for future metal bands.
2. Led Zeppelin
While often categorized as hard rock, Led Zeppelin’s influence on heavy metal is undeniable. Formed in 1968, they pioneered the blend of hard-hitting blues rock with mystical, otherworldly themes. Jimmy Page’s groundbreaking guitar riffs, Robert Plant’s wailing vocals, and John Bonham’s powerful drumming made them a force to be reckoned with. Songs like “Whole Lotta Love” and “Immigrant Song” showcased the raw power and aggression that would define heavy metal.

5. Motörhead
Motörhead straddled the line between heavy metal and punk, creating a fast, aggressive sound that prefigured thrash metal. Led by the charismatic Lemmy Kilmister, Motörhead embraced speed, chaos, and rebellion. Their 1977 album Overkill introduced the double bass drumming technique that would later become a staple of thrash metal.
