What a slugfest! In Round 1 of March Metal Madness to determine the Best Debut Metal Album of All Time, two of the noisiest, most chaotic metal bands compete as Slipknot's self-titled debut against Napalm Death's grindcore-spawning Scum.

Slipknot turned heads inside the industry as everyone recognized metal's next big sensation. On their self-titled debut, the masked troupe took the pummeling, downtuned groove of nu-metal, combining it with the brute force of extreme metal's concussive drumming and the rage-personified Corey Taylor who fitfully barked his way through angsty, relatable lyrics.

Napalm Death's Scum is one of the most interesting debuts in metal, comprised of two different halves featuring two different lineups. Regardless, their abrasive sonic mutation of punk was the fastest music in the world, inventing a new style with their abrasive vision of extreme metal.

So which album will move on to Round 2 of March Metal Madness 2017? Vote below for either Slipknot’s Slipknot or Napalm Death’s Scum as the Best Debut Metal Album of all time in the poll below!
