Attic's convincing, raw, classic old-school heavy metal follows a diehard path forged by traditional Mercyful Fate, Pentagram, Judas Priest and Helstar yet resounds with modern production, and is portrayed through a dark, dense atmosphere. Surging with nearly fifty minutes of this huge-sounding blend, The Invocation was recorded at The Underworld Studios and produced, mixed and mastered by Mersus (Destroyer666, Gospel of the Horns, Zarathustra), bearing cover artwork by Markus Vesper (Manilla Road, A Tortured Soul, Poison Oath, Headless Beast).
