Probably the heaviest song I heard in years. All album is amazing.
Start with classic old school death metal bands - Morbid Angel - Altar of Madness, Death - Scream Bloody Gore, Leprosy and Spiritual Healing, Atheist - Piece of time, Cancer - To the Gory End, Obituary - Slowly We Rot, Autopsy - Severed Survival, Deicide - Deicide to name a few.I've never been able to gain a taste for black/death metal. Is there a band you'd recommend?
