Black metal music in particular has a definitive "screaming" style which constitutes a vast majority of the genre's vocal work, though this is done in varying degrees. Some black metal acts use this approach as a simple rasping sound, but others use a louder, more "grim" scream to emulate the cold, evil, and frightening atmosphere black metal would portray. Vocalists like Ihsahn of Emperor, Grutle Kjellson of Enslaved and Pest of Gorgoroth use loud screaming in their vocal work, while other vocalists take differing approaches; for example: Shagrath of Dimmu Borgir once used a style on par with loud roaring in the band's "Enthrone Darkness Triumphant" days, and vocalists such as John Gossard of the San Francisco band Weakling and Pasi of the Finnish band Darkwoods My Betrothed used a style that sounded more like wailing mixed with the genre's present screams.
