Though it's an imperfect designation, symphonic black metal is the most common term for a European-centered style that emerged in the mid- to late '90s. It isn't literally symphonic, of course; that simply refers to the thick-sounding instrumentation and sweeping, dramatic soundscapes. Nor is its connection to black metal always readily audible; although nearly all of its bands started out playing standard-issue black metal, symphonic black metal often bears little surface resemblance to its immediate forebear. The starting point for symphonic black metal was the early-'90s sound of Norwegian black metal, specifically the wing of bands that employed sorrowful, melodic keyboard lines as a counterpoint to their furious assaults.
