There are certain bands that can be pointed to as incredibly influential on what would become known as black metal – Black Sabbath, Venom, and Mercyful Fate among them. Two other surefire inclusions in that list are the two Swiss bands fronted by Thomas Gabriel Fischer (aka Tom G. Warrior): Hellhammer and Celtic Frost.
With an emphasis on detuned, grinding, mid-paced riffing rather than shredding (along with growled vocals and demonic lyrical subjects), the influence of Fischer’s guitar work with the two bands can be heard in groups like Mayhem, Sepultura, and Behemoth, plus even bands outside of the metal universe (Bleach-era Nirvana, for instance).
