Rush and Nas were on the Colbert Report playing Tom Sawyer on Rock Band for the Xbox 360. Kotaku says Nas outperformed Rush on their own song, and for the most part he did. In Rush’s defense, playing guitar solo on Rock Band is way easier than having an entire band set up with vocals and drums in addition to the guitar. We still think Rush rocks. Plus, Nas is using a Guitar Hero guitar. What a hack.
