Melodic metalcore is a fusion of melodic metal and hardcore punk. It features aggressive vocals, heavy breakdowns, and intricate guitar work. The melodies are often more complex than traditional metalcore, with an emphasis on harmonies and catchy hooks. The lyrics often deal with personal struggles, social issues, and political commentary. Melodic metalcore has gained a large following in recent years, with bands such as Killswitch Engage, Trivium, and As I Lay Dying leading the way.
