Plus, where to start with Suffocation?
Icons of Evil was a pretty boring album in my opinion. As for Suffocation, start with either Pierced From Within, Despise the Sun, and/or their self-titled release.
They won an important prize at Metal Hammer's Golden Gods 2007 award (best underground band if I'm not mistaken).
Metal Hammer is run by cocksucking posers.
You should pick up Terrorizer Instead.
