the only other thing i'd suggest is that those live versions of king kong are really existent in the midpoint between period davis and early doors.

i am not a doors fan - i think they were terrible.

but, i think that ray manzarek's influence on both fusion and progressive rock is rather understated.

early zappa was, in some ways, a parody of the doors. it was zappa that went to town with it and gets most of the credit.

but, it was really the doors that presented the document 0, as it was.

if you ask roger waters, he'll tell you they were initially based on the doors, as well - which is key, as they were the first to do it in the uk.
