We've added "Black Star" of Carcass + Slaughter and Blinded of At the Gates.
Always liked those classiks but never played them actually (pretty straightfoward anyway)
Great choices for At The Gates, and for the Carcass cover, I love that song but it´s definitely not a fan favorite nor a Death metal classic in any way, although if I were you I´d still do it just cause I love it and to show that you´re not just doing the same classics everyone does (fear of the dark anyone?)
