This is Decapitated, from "The Negation." No Polish jokes please, as they are Polish. The drummer on this album died not long ago. He is fondly remembered.
This is Obscura, from Germany. This track is the best one on "Cosmogenesis."
Revocation, from the States. This is from "Existence is Futile," their newest.
And some good 'ol Dillinger Escape Plan, just to slow things down a bit. This is from "Ire Works."
