For All Kings feels like a gushing love letter to the days of classic heavy metal, when teenage headbangers carved “Iron Maiden” into their school desks. There’s certainly plenty of scowling thrash to be found on “You Gotta Believe” and “Evil Twin.” Yet the band nimbly counterbalance snarling aggression with Joey Belladonna’s soaring vocals and the dizzyingly melodic fretwork of Scott Ian and Jon Donais. When Anthrax launch into “All of Them Thieves,” it doesn’t feel like a song so much as a triumphant march to the top of a mountain.
