Which of these rock stars contributed to the soundtrack for the adult film "Sacred Sin"?

Michael Ninn is an adult film director and writer. He began his career as a music video director and made his first adult films in 1992

Ninn's production company, Ninn Worx, has produced dozens of films that have won more than 70 Adult Video Awards.

In 2006, Eddie Van Halen contributed two instrumental songs to the soundtrack of Ninn's adult film "Sacred Sin".

He even held a release party for the film at his Chatsworth home, reportedly filled with scantily clad and/or naked girls everywhere and half-naked Cirque du Soleil-type performers doing acrobatics in and outside the house. There were guys on stilts walking around, there were rock stars and porn stars galore, there was an open bar, tons of great food and hor's d'oeuvres, plus Eddie played a set of Van Halen songs with an all-star backing band, and later entertained a small room with a piano recital!"
