I had no idea Danny Masterson had a career outside of his acting roles and his role as Steven Hyde in That '70s Show, but apparently he's also a DJ who performs at night clubs under the name DJ Mom Jeans (formerly DJ Donkey Punch).

Here, you can see DJ Mom Jeans performing at Square Enix's Final Fantasy XIII launch party, giving the new RPG's theme music a dance remix as scenes from FFXIII play behind him. If you like the song enough to want to throw it on your iPod or add it to iTunes, Siliconera even has a downloadable (and sort of low quality) MP3 from the live performance.
