This is by far Pantera's darkest, bleakest and heaviest album. This is where they went through the ceiling and pushed everything to the limit.The brutality and skullcrushing factor of the material on here is next to overwhelming. The title track caves your head in when it screams in at the beginning, and 'Drag the Nerve' features an extremely doomy riff, which conjures up visions of the Grim Reaper himself. '13 Steps To Nowhere' is dark and heavy, and 'Suicide Note part 1' is eerie, but 'Suicide Note part II' and 'Sandblasted Skin'are the most thrashing, screaming and insanely mental things Pantera have ever recorded.They also have a successful stab at stoner rock with 'The Underground In America'. This album has a massively brutal charm to it. Buy this, and 'Far Beyond Driven', and you will recognise the meaning of the word 'heavy'.
