Jeff Wagner calls Grand Declaration of War "Mayhem's own Into the Pandemonium, an album that had perverted and turned inside out the black metal genre as Celtic Frost's Pandemonium had done to thrash metal".
Jeff Wagner komentira kako je Grand Declaration of War "Mayhemov vlastiti Into the Pandemonium, album koji je izopačio i izokrenuo žanr black metala - istu je stvar Celtic Frostov Pandemonium napravio thrash metalu".
