Two CDs. 2021 release. This release marks 30 years since the formation of one of the most enigmatic and aurally captivating bands to grace the dark rock/prog genre, Mnemosynean contains an extensive collection of all of Katatonia's rarities and B-sides, including tracks from the band's numerous EPs, limited special edition bonuses, cover songs, as well as a series of collaborative remixes. The journey of Mnemosynean spans the gothic-soaked experimental epic 'Scarlet Heavens' recorded all the way back in 1994, through to tracks recorded during the sessions for the stellar 2016 opus, The Fall of Hearts.
