Guitar Hero Craziness

I was just watching a live feed of Bill Gate's keynote at CES and towards the very end the Guitar Hero world champion known as "Tipper Queen" made a guest appearance and very briefly showed what she can do with the axe.  I looked her up on YouTube and found the video embedded below... anyone who has played Guitar Hero will appreciate just how awesome this is:

I wonder if Slash of Guns N' Roses and Velvet Revolver fame, who also made an appearance with Bill Gates (talk about selling out) could beat Tipper with enough practice... somehow I'm not sure he could.
