New York death metal legends Suffocation have been one of the world's most brutal bands ever.

Already with a 25-year legacy of violence in their past, Suffocation's 2013 full-length, 'Pinnacle of Bedlam,' is arguably their best album since their 1995 masterwork 'Pierced From Within,' and 'Cycles of Suffering' is a Suffocation studio track that truly captures how heavy the group are live in concert. From literally zero seconds in, the brutality is unrelenting.
