Seconding Daughters of Darkness. It's great the way all the characters turn out to be completely amoral. Also see the Hunger, Vampyros Lesbos or, if you're so desperate to see lesbian vampires that you don't mind sitting through pretentious b-grade horror "art" -- Shiver of the Vampires.

Honestly though, I have to say, the plots of most of these 70's vampire movies, especially the European ones, are really formulaic with little diversity.

If you're going the Franco route there's also Female Vampire.

Vampyros Lesbos has the greatest of soundtracks

Yeah, it's really good although some of my favorite tracks on the soundtrack album are actually from a different movie.

If you're into that stuff I recommend the Nerosubianco soundtrack by The freedom and anything from that period by The Cordara Orchestra.

And especially the recently reissued LP of the Werewolves On Wheels soundtrack (the CD is completely different and seems to have been taken from a film print, complete with all of the movie sound and the weird edits that were made to make the music fit the picture). It's like a mediocre 70s country singer songwriter went kind of crazy and turned into a one-man Scandanavian psychedelic commune band. Mostly because that's kind of what happened.

Do people actually watch these for the plot? I watch them for the music, the cinematography, and the boobs. In that order, because I'm weird.

And what amazing titties they are!

British horror at this period provided some of the better prime totty to see on the screen. THAT IS WHY IT IS IMPORTANT.
