There’s more sustained eroticism in these scant 75 minutes than in most four-hour, two-disc gonzo opuses.

Inspired by the “rock-porn-subculture” Razordolls Website, with its sassy, slutty rebel girls, this swift six-scener is grungy and giddy yet constantly strokeable. Forget the imitators and the wannabes — JackTheZipper remains the edgiest of alt-porn creators.

Almost half the running time is an homage to the perverse beauty and ravenous sexuality of teen sensation Sasha Grey. From her eerily erotic masturbation to a scalding double blowjob on James Deen and Alec Knight followed by high-energy buttfucking, it’s molten heat.

JTZ moves easily from the naturalism of the Grey sequence to stylized color manipulation in a scene with tattooed cutie Regan Reese. Two pale-skinned girls, Jade and Stoya, blow bubbles in a sunny room, then very prettily eat each other. That segues into a speeded-up punk couple orgy, followed by the finale with total porn whore Annette Schwarz taking dick in her ass in a luridly lit abandoned rock club.

Altogether, this is a somewhat lighter offering from JTZ, but that first half-hour with Grey and the guys ranks among his crowning achievements.
