A genre of new age metal that began in the late 1990's with bands like Slipknot and Killswitch Engaged. It infuses Punk and Extreme Metal to create a strong, yet complex rhythm. It differs from Punk Metal by putting emphasis on the breakdown portion of the song, and often invoke a more depressed and somewhat hopeless feeling. Some other modern examples include Attack Attack, Underoath, Atreyu, Trivium, All That Remains, and many more.
