Ow! My anus!
If you thought Expert tracks in GH1 were hard then GH2 is going to ask you to bend over. These are 2 of them from the Face Melters tier; Beast And The Harlot and Misirlou.
For you that don't know the games: in Guitar Hero the songs are split into tiers according to difficulty. The Face Melter tier is the hardest. In Guitar Hero the Face Melters were Godzilla, Texas Flood, Frankenstein, Cowboys From Hell, and Bark At The Moon. Bark At The Moon is supposed to be the hardest but some people, including me, say that Cowboys is harder cause its longer. In Guitar Hero 2 Beast and the Harlot, Institutionalized, Misirlou, Hangar 18, and Free Bird (5 minute guitar solo! neeeeyah! Doesn't sound like a hard song but its 10 minutes long so that ramps difficulty) are the Face Melters.
