1987 Sleaze classic featuring some great equipment and some not so great music.
I chose Slumber Party Massacre II for the reason that the women in the movie are in a fictional rock band. The "Driller Killer" plays an amazing half-guitar half-drill that he dances with before killing his victims. He is a cheesy rockabilly guy with a fringe leather jacket. It is a B movie to the fullest. Lots of boobs, sex, funny one-liners and gory murders.
