The Chilean underground scene has been thriving for years with great bands of all styles of extremity. Occasvs is both unique within that scene and also a fitting encapsulation of it combining black metal with death heavy metal and more while lying in wait for years as their long-in-the-works debut album was fine-tuned. Now Nocturnal Majestic Mysteria is to be unleashed on the world in late summer 2017. The first streaming track from the release Union is an 8 minute odyssey through all of the band’s startling blend of ideas and influences. Tremelo-picked riffs intertwine around blast beats and the vocals are growled shrieked and even sung in eerie stentorian harmonies. Listen to it here.
