The incredibly heavy and critically acclaimed 'Koloss' by Swedish extreme metal giants Meshuggah sent a bolt down the spine of metalheads after the album's release on March 27. Hailed as a probable contender for the best extreme metal record of 2012, it's no wonder why fans took Meshuggah all the way to our Death Match Hall of Fame. Much like drummer Tomas Haake says, 'Koloss' is “best avoided by the faint of heart.”
