Proto-Metal
Located in 2 routes
The loud, fuzz-saturated late-60s/early-70s heavy rock that pointed toward metal without quite being it yet — blues-rock and acid-rock pushed to extreme volume and distortion. Sound: thick overdriven and fuzz-pedal guitar tone, lumbering or hard-charging riffs built on blues scales, prominent distorted bass, heavy-handed drumming, extended jams, and bluesy or wailing vocals. Tempos swing from sludgy crawl to wild boogie. The mood is raw, primal, and psychedelic-tinged, with occult or sci-fi imagery starting to creep in — the genre's DNA assembling in real time before the word 'metal' described a style.
History
Proto-metal coalesced in the late 1960s as bands cranked blues-rock through louder amps and new fuzz/distortion units. American power trios led the volume race — Blue Cheer's Vincebus Eruptum (1968) is often cited as the heaviest record yet made, while the Detroit garage of the MC5 and the Stooges added primal aggression. In Britain, Cream, the Jeff Beck Group, the Yardbirds and Led Zeppelin's debut (1969) forged the heavy riff template, and Deep Purple's In Rock (1970) sharpened it. The term 'heavy metal' itself surfaced in a 1971 Creem review of Brooklyn trio Sir Lord Baltimore's Kingdom Come (1970). Other key crucible acts — Iron Butterfly, Steppenwolf, Mountain, Coven, Pentagram's earliest demos — fed a loud, dark current that Black Sabbath would crystallize into true metal, retroactively defining everything before it as proto.
