女魔血宴 (1972)

Taglines: Probing the Black Depths of Hell!
Mara - Queen of the black witches and her wolf-pack of voluptuous virgins invade Satan's tortured realm of the unknown!
A terrifying, screaming plunge to the depths of hell!
YES! Another classically demented cheesy extravaganza from auteur Ted V. Mikels! You know, the genius who gave us The Astro Zombies, The Girl In Gold Boots, and The Corpse Grinders.
Frankly I am surprised this is not already on the site, but a search did not yield its presence.
All about an evil witch cult into murder and groovy dancing. Mara (Lila Zaborin) a "black" witch, practitioner of the occult, black magic, and evil incarnate, is the leader of a coven of voluptuous, scantily clad beautiful young women who vent their sadistic love and passion for pain on helpless victims as they perform the bloody ritual of a hideously macabre dance of death, carrying aloft flaming torches and plunging spears into their human male sacrifices in a gory ceremony to titillate their pulsating pleasures and sanctify the evil desires of this Queen of the Witches.
The musical score alone may have you groaning in agony... but of course, this being Ted V. Mikels, I suppose you would expect to be groaning in agony. Lovers of bad cinema will wallow in deep hurting!
