Yeah, Run to the Hills block is the last of the Hard level. I finished it on hard, and got though I THINK 3 blocks on expert and have hit a wall. I'm just not that good at playing real drums yet, though I am practicing. To give myself the benefit of the doubt, because I am so awesome, I have not played Rock Band in a few weeks seriously, but I have been playing drums for about a half hour a day-ish. Mostly playing to tunes on my iPod, but I think it is still good training.
You should totally come up for Kublacon! Das Hookarz await! This time you should come with an action plan for success with the ladies of the night!
