2011's The Great Mass is a symphonic masterpiece that constitutes a quantum leap in the art of amalgamating orchestral music with heavy metal. Septicflesh's material here is the audible evidence of guitarist Christos Antoniou finishing his studies of classical composition with academic honors and distinction. The Greeks took the next logical step in following the course they successfully set on their celebrated comeback-album Communion (2008). The Great Mass shows this band at the peak of their evolution, combining massive deadly guitars at the edge of blackness with haunting gothic melodies and cinematic symphonic arrangements. The orchestral parts were recorded with the FILMharmonic Orchestra Prague including full choir and boy soprano. Renowned producer Peter Tägtgren (Dimmu Borgir, Immortal) created the massive sound of The Great Mass. Gatefold colored vinyl LP.
