The origins of metalcore date back to the mid-1980s, where bands like Agnostic Front and Suicidal Tendencies were mixing thrash, punk, and hardcore together. The genre became huge in the late '90s, as a major wave of metalcore bands formed to tear up the metal landscape. Bands like Unearth, Killswitch Engage, and All That Remains have made names for themselves in the mainstream, headlining major festivals and achieving solid albums sales. Today, metalcore is still one of the most popular genres of metal, even with criticism from some in the underground metal community.

Musical Style:
Metalcore is structured linearly, with the songwriting consisting of aggressive verses and melodic choruses. Breakdowns are a vital part of the genre, usually used to invoke moshing at live shows. A good portion of the bands in the genre have recently added in solos and a greater emphasis on technical guitar playing, including a heavy use of palm muting. Double bass drumming is prevalent in the genre as well. The sound is polished and the lyrics range from personal to political issues.

Vocal Style:
Most vocalists scream and growl, with some saving the clean vocals for selected points in the song (chorus, bridge).

Metalcore Pioneers:

Earth Crisis
Formed in 1991, Earth Crisis made a splash in metalcore with their 1995 debut album Destroy The Machines. The album is considered one of the most influential albums towards garnishing mainstream recognition of the genre. Earth Crisis released a few more albums that showcased a cleaner and more refined approach to metalcore before dissolving in 2001.


Shai Hulud
While some today may consider the band to be closer to a hardcore/punk hybrid, Shai Hulud was considered a pioneer of metalcore back in the mid '90s. Their 1997 album Hearts Once Nourished With Hope And Compassion was an anger-fueled journey; however, Shai Hulud brought intelligent lyrics to the forefront of their music, helping them to achieve critical and commercial acclaim.
