Swallow The Sun have released their video for new song ‘Cathedral Walls’, taken from their forthcoming record Emerald Forest and The Black Bird. The video can be viewed below. The new song, which is the band’s first new output since 2009’s New Moon record, features fellow Finn, Annette Olzon from Nightwish, who delivers an utterly beautiful performance, although that is not her in the video. The gloomy death/doom band has always been consistent with their records, dating back to 2003’s first full-length, The Morning Never Came. Emerald Forest and The Black Bird is sure to be a highlight for the year upon its release on February 1st through Spinefarm.
