Japanese black metal legends Sigh formed in 1989/1990. As the band reaches the milestone of thirty-five years of existence, it was also time to re-visit their 2007 opus, 'Hangman's Hymn'. A compositional powerhouse in itself, the title was notably Sigh's first concept album; a mix of fast thrash metal from the 80s such as Wehrmacht, Sarcofago, Repulsion & classical music - especially German symphonies. However, "Hangman's Hymn" was always perceived to be not fully up to the band's own standards and expectations in it's execution and production, and so main-man Mirai Kawashima set about to finally do justice to this at times overlooked masterpiece of intricate songwriting, by making a full re-recording with the current Sigh sound and delivery, under the title of "I Saw the World's End - Hangman's Hymn MMXXV".
