Also if you are a metallica fan my favourite work by them is the live recordings they did in 3 nights in Mexico City from their boxset. That is actually my favourite live recordings now that I think about it.
If your havent heard it check out Children Of Bodom's Stockholm Knockout. I've got the DVD and i bought two sets of the double disc set cuz i lost a disc and loved it so much i had to buy it again. This cd is what got me into cob!
