Lamentari is now streaming their massive, and I do mean massive, new single "Synodus Horrenda." The single is off Lamentari's coming EP Clavis Aurea, which interestingly was recorded in-studio with the concert Yamaha grand piano originally owned and toured with by the legendary film composer Ryuichi Sakamoto.
Clavis Aurea was mixed and mastered by Stefano Morabito (Fleshgod Apocalypse) at 16th Cellar Studio. Check out Lamentari's music here on Bandcamp.
