|Lucifer's Friend released their debut album which is just as much proto-doom as Black Sabbath only in November 1970, but most of the band already released another heavy (but not as much) album under the name Asterix earlier that year.|
The Butterfield Blues Band delivered a lengthy instrumental solo track on East-West in 1966, which is possibly the start of acid rock (and thus all later heavy psychedelic rock)
Link Wray's Rumble from 1958 is the earliest distorted guitar soloing I'm aware of.
Screamin' Jay Hawkins' "I Put a Spell on You" from 1956 is probably the earliest song that could be considered heavy, but at that point it's really just voodoo blues.
|check blue cheer, the stooges, MC5|
|Blue Cheer seems like the obvious thing here|
The Kinks deserve a mention for early distorted guitars
Then you got Lower East Side people like David Peel and The Godz and The Fugs not really doing metal but being heavy and weird and punk
Love - 7 and 7 Is has gotta be one of the heaviest pre-69 songs out there
|O shit, The Fugs. That's something you have to check out.|
|there's a bunch of weird 60's garage that was heavily distorted and went into dark psychotic drug-fulled rantings. Very metal. but that's a whole rabbit hole you'd have to go into.|
|Two early distorted guitar blues:|
"Cotton Crop Blues" by James Cotton (1954)
"She May Be Yours" by Joe Hill Louis (1953)
Muddy Waters - Electric Mud album (1968) pretty much inspired every guitarist that year forward
|Yes Lucifer’s friend, love Everybody’s Clown from the debut|
Also Blue Cheer, Steppenwolf, Ten Years After -Their undead album jams from 68,
I also think Live Dead from The GD has some heaviness to it
Great list idea by the way
|As a curiosity, I would mention that Paul Hindemith wrote what's basically an early death metal solo as the 4th movement of his viola sonata op.25 no.1 way back in 1922 (published 1923).|
"Frenzied time measure. Wild. Beauty of tone is not important."
I would not consider classical shred a la Paganini as metal in this sense since those kind of passages still sound as reference to classical when you shred them on a distorted guitar. This one is the other way around.
|i thought everything was invented when black sabbath was born|
|I'm glad to see "The Nile Song" on this list. Probably Floyd's best song that came out in the period that followed A Saucerful of Secrets and preceded Meddle.|
I also still need to check that Mayall album. I've heard it get lauded as being one of Eric Clapton's greatest accomplishments (along with Cream, who I absolutely love).
|Although recorded a day after Black Sabbaths debut was released The Whos cover of Young Man Blues from Live at Leeds is basically a geed up Sabbath |
