Yes, Slipknot is famous, but it isnt my favourite style of metal. But I ve got repsect for them and there masks are awsome.
When Ive got the time I am gonna look for FFDP, Hatebreed and Mudvayne, maybe I will buy them if I like it. Thanks for the tip.
I would suggest for FFDP - War is the Answer, Under and Over It, Lift Me Up.
Hatebreed - Honor Never Dies
Mudvayne - Dig
..I don't really like dubstep. It's not music, it is a bunch of sounds compiled together, and you will never be able to listen to it live.
