I don't think Lemmy saw himself as a visionary
I doubt any of the folks I mentioned did.
If you listen to Peter Hook's Reverb video, he explains exactly how he ended up with his sound in Joy Division.
They're all pioneers, because their style was studied & copied (they opened minds). Lou Barlow of Dinosaur Jr. specifically mentions Lemmy & plays some of his riffs in his Reverb interview, but I can't post it here, he does curse once.
I didn't try to make an extensive list, just folks that influenced how I want to sound.
IMHO Mr. Sheehan is to bass as Steve Vai is to guitar.
