2014 album from the influential Hard Rock band. After six turbulent years Slipknot returns with one of their heaviest and most intense body of work - 5: THE GRAY CHAPTER. Stretching from grief to anger and beyond the album touches on the most difficult period of the band s career and serves as a tribute to a lost friend and bandmate. LED by the ferocious The Negative One and the first single The Devil In I the album ranges from the raw moments from the bands self-titled debut and follow-up Iowa to the dynamics of VOL. 3: THE SUBLIMINAL VERSES and ALL HOPE IS GONE. 5: THE GRAY CHAPTER is classic Slipknot while remaining fresh and innovative and proves Slipknot continues to be the premiere heavy band of this generation.
