Nas was out in Aspen, Colo. yesterday as the special guest at the Winter X Games, though he wasn't just there to chill and watch some snowboarding action. In addition to presenting awards to the winners of the Snowboard Street portion of the games, he grabbed the mic to perform his still-ill single "Nasty." You can watch it all go down in the above video. Hopefully Nas will let us know when his new album, Life Is Good, is dropping.
