In the new Guitar Hero 3 game one of the most infamously difficult songs is by far “Through the Fire and Flames” by the band DragonForce. In fact I have yet to see a video that showed someone getting 100% on it. I do not think there is another song out there out of any other Guitar Hero game that has not been 100% completed (on expert). The closest thing I have found on youtube was this video. Although its not a 100% completion it is still pretty damn impressive. Check it out below!
