Protometal/hard rock

[Manic Ferocity]

I've been interested in seeking out more stuff that can't really be technically classified as "heavy metal" but had a vast influence on the genre. Recommend me stuff like Blue Cheer, Deep Purple, and Sir Lord Baltimore.

Not sure who you already know, but definitely check out Uriah Heep if you haven't.

Rainbow(Guessing that you haven't listened to them)

 

[Manic Ferocity]

I've heard Rainbow. I'll check out Uriah Heep.

Yeah, I second Uriah Heep as well. I have Return to Fantasy and Demons and Wizards
