When these incite-ful Iowans first surfaced two years prior, nobody quite knew what to make of the masked nine-headed hydra. Stuffing nu-metal, gangsta rap, industrial, death metal, and thrash into one diabolical dirty bomb, their self-titled debut’s detonation racked up a lot of damage but lacked discipline. Their sophomore ode to their home state dialed up the rage while simultaneously honing their focus. Proclaiming the mathematical equivalency between humans and feces, declaring their demonic allegiance via death metal, and borrowing the name of an ugly evangelical Christian novel for their most melodic meltdown, Slipknot truly earned their jumpsuits here.
