What the thing is
Heavy metal is a genre of rock music defined by distorted guitars, emphatic beats, extended solos and loudness. Its core technique relies on high-volume amplification and heavy fuzz.
Where it came from
It developed in the late 1960s and early 1970s, largely in the United Kingdom and United States, with roots in blues rock, psychedelic rock and acid rock. Led Zeppelin, Black Sabbath and Deep Purple were all founded in 1968.
What it gets right
It establishes the electric guitar’s amplified power as the genre’s central element. It codifies distortion, palm muting, extended solos and loudness as structural features — not effects, but grammar.
What it gets wrong
It does not yet function as a unified genre in 1970. The sources confirm it was still a dispersed set of practices — ‘scavenged’ sounds, scattered aesthetic cues — not a coherent movement or scene.
Why it matters now
It matters because its 1970 state reveals how genres form: not through manifestos or labels, but through repetition of technique across bands, then later consolidation — here, achieved only by Judas Priest in the mid-1970s.
Is it worth your time
Yes, if you want to understand how amplified guitar technique and transatlantic hard rock coalesced into a distinct sonic code — not as myth, but as documented stylistic consolidation.
