Or are they zombies? No, let's go with vampires; they move too smoothly to be zombies. The black-ish metal track adds to the ambiance. Titled "The Flowers of Evil", the video is one of two introducing AP's Soiree line of unmentionables. The 2nd "short film" (watch here) has a less interesting "Eyes Wide Shut" feel to it, but does feature some light whipping of a ganged-up-on naked gentleman.
So, something for everybody.
