Mayhem's innovations reach every branch of black metal's genre tree. The pioneers' tremolo-picked dissonance has seeped into Enslaved's proggy epics full of Viking lore (“Wotan”), and their blast beats pop up in Marduk's surging tempos and percussive assault (“Materialized in Stone”). Wolves in the Throne Room are also followers, folding Mayhem's textured distortion into dark, synth-laced ambient (“Subterranean Initiation”).
