The original masked star of the FRIDAY THE 13TH movies now makes his living singing heavy rock tunes about serial killer character JASON VORHEES at horror film conventions. Actor-turned-rocker ARI LEHMAN played psycho Vorhees as a teenager and now he fronts a Chicago, Illinois group fixated by the movie killer. Lehman tells men's magazine Blender he's keen to reveal his former horror movie character's "backstory" in his group's songs. He explains, "I have this idea that Jason survived as a child underwater, like SWAMP THING."
