President and CEO of Double Fusion, Jonathan Epstein put all the other GDC rock gods to shame this week at IBM's Guitar Hero Competition. Epstein won the $US 1,500 grand prize with his face melting rendition of Eric Johnson's White Cliffs of Dover. According tho the short press release, you can challenge Epstein to an epic battle of the bands by going to Double Fusion's website. I went there myself and didn't really see a place to sign up per se, but I suppose an email will do nicely. Just don't count on wrestling that $US 1,500 from him. I think the title will be the best you can hope for.
