In The Mouth of Madness

Lo, gentle reader, the night grows darker and stranger and I fear I have not the strength to continue much longer with this confession. I have seen things most terrible tonight, and I have been a part of them. This series of aughts and zeros is testament to the horrible labour of John Carpenter and Jim Lang, concentric circles within spirals descending into unknowable oblivion. The initial cacophony may be shocking, with seemingly ancient arabesque guitar music from the distant and scarcely mourned 1990's, a brutish dark age; after this is endured, however, the listener may settle into a black fugue of meditation only occasionally interrupted by the odd axe murder or ruptured threshold.
I'll not spoil the ending for you.
