First Slipknot album was excellent, loved the hip hop/drum and bass elements with some proper chugging riffs. Angry, angry album.
Don't listen to their other albums much as I hate the ballady bollocks they tend to drift into. Never listened to Sour Stone. Heard them as I was packing up my tent at Download but that was about it.
Someone gave me a CD of early Slipknot bootleg stuff and it was sick, sounded like it was recorded in someones bathroom but was angrily awesome.
The oldest and strongest emotion of mankind is fear, and the oldest and strongest kind of fear is fear of the unknown.
