What do DJ AM, Travis Barker, Jay Z, and Eminem have in common? Videogames? No, they don’t. Well, maybe they do, but from what we all know, that’s not quite it. That’s the case, except for Monday night when they all were given lots of money to promote DJ Hero at the Wiltern Theatre in Los Angeles. I was there, and I can tell you that while it was enjoyable, the climate was a strange one to say the least, as this wasn’t so much for us game journalists as it was for the music business. Unfortunately, I’m not very good about spotting faces, but I do understand Kim Kardashian was about, and some others. Even in my oblivious state, though, it’s bragging rights I’ll take.
