Opera metal is a fusion genre that combines elements of heavy metal music with the dramatic and theatrical aspects of opera. This style often features powerful vocals, orchestral arrangements, and complex compositions, creating a unique sound that appeals to fans of both genres. Typically, opera metal bands incorporate operatic singing techniques, including soaring high notes and dramatic storytelling. Notable bands in this genre include Nightwish, Epica, and Within Temptation, who blend heavy guitar riffs with symphonic elements, resulting in an epic and immersive listening experience.
