Enter the dark celestial halls of the Mephistos, where the Archon reign supreme! Hæresiarchs Of Dis pushes the boundaries and conceptions of modern extreme metal by arranging soundscapes and atmospheres with overflowing occult passages, acoustic intervals, ghostly & cavernous interludes, funeral organ and cello amongst other instruments, and choral vocals. Well placed atmospheric segments provide an ambiance that many struggle (or fail) to achieve, as Hæresiarchs Of Dis easily engages the listener with complex multilayered, multidimensional compositions and concepts.
