It was the last guitar solo; my fingers were so wearied I couldn't chain notes together fast enough. I stayed in Medium after that, never satisfied due to its easiness, but never capable enough to take on Hard. I'd hit a brick wall.
Sounds familiar, doesn't it? Mark it down to non-logical note structures. Neversoft had six months to get GHIII out on shop shelves. So chord layouts on the last tiers were functionary and a test of finger skills only the hardcore could achieve. And even they, while nailing a guitar solo, would never twitch a smile."
