I love the bizarre horror of the 70s - any good recs?

I always used to be able to tell the obscure oddball 70s horror cuz they'd usually be in those oversized VHS boxes (all the b-horror hunters out there know what I'm talking about, we'd always be the first to reach for those big-ass video boxes, heh!) mostly found in the for-sale racks at all the old local video shops... ah, the good old days of video stores. Anyway, heres some I thought of for now that I've seen over the years, feel free to add some recommendations! (if you have some good ones from the 80s, thats ok too! I stuck to the 70s for now, I'd be typing this all night if I included all my 80s favorites too)

I also feel like there's a lot of bizarre Euro horrors (besides the obvious stuff like Bava and Argento) that I'm blanking on. I'll add some more later on when I think of some more.
