All were invented in the UK and came stateside. Maybe not so much.
Vincent's band got rolling in 1966 while in High School, as _The Spiders_ and there wasn't much
"shock rock, Hard Rock/Heavy Metal, and even goth rock" to be found, the niche they moved into around early 1968, when the Band was looking for their gimmick, and picked the occult for their increasingly performance art rock. Being in LA, were not much influenced by the Detroit area MC5 or _The Stooges_, or Bloodrock from Fort Worth
No Vincent, that group would have found another Frontman, and probably have some impact, but not as much as OTL
