Sonically triumphant and lyrically war-obsessed, Sweden's Sabaton have been a major force in the power metal field since the mid-2000s. Since debuting in 2005 with the World War II-themed Primo Victoria, the band has amassed a loyal army of European followers -- they have their own annual festival and cruise -- and released a slew of acclaimed albums, including the platinum-selling Carolus Rex (2012) and Heroes (2014), and 2019's and 2022's World War I concept LPs The Great War and The War to End All Wars.
