Eddie Van Halen has teamed up with adult video director Michael Ninn to write and perform two songs for his upcoming Ninn Worx production, Sacred Sin. The rocker makes no excuses for his decision to work in the adult industry. "I'm working with a friend -- very simple," Van Halen told adult site http://AVN.com. "I like his work. Michael Ninn is like a Spielberg to me: the imagery, the way he makes things look, just...sensual." To Ninn's "sensual" cinematography, Van Halen will add two tracks tracks, "Rise" and "Catherine," the latter of which is a remix of the theme to a Ninn film of the same name and has "a 'Kashmir'-Led Zeppelin kind of feel to it now," Ninn told AVN. Sacred Sin, which Ninn said is aimed at the "couples market," will be available on Sept. 13 and will feature music videos for both Van Halen songs. But Van Halen fans who prefer their sex tapes soft-core needn't worry: Ninn is also cutting a non-explicit version of the movie which will be called Rise. No release date has been set.
