In 2004, the US gothic band Nox Arcana released Necronomicon, their musical ode to H. P. Lovecraft and the Cthulhu Mythos. A fantastic piece of dark audio art for all Mythos fans and musique noire lovers.

The Necronomicon is said to contain the lost knowledge of the Elder Gods, the ancient lords of darkness that held dominion over the Earth aeons ago. Believed to hold the key to opening forgotten gateways between worlds, the text prophesies the return of the Great Old Ones and contains forbidden rituals of summoning that will bring about their resurrection.
Now, for the first time ever, the Necronomicon is set to music with this dark symphony by Nox Arcana. This epic concept album based on H.P. Lovecraft’s legendary book of shadows features a mixture of exotic, dark fantasy themes with 21 tracks of ominous orchestrations, Gothic choirs, Egyptian and Middle-Eastern melodies, eerie voices and otherworldly chants. This musical grimoire is a spellbinding tribute to the Cthulhu Mythos—a powerful and sinister soundtrack to evoke your darkest nightmare.
This cd is dedicated to the memory of Howard Phillips Lovecraft, with special thanks to August Derleth and Arkham House for keeping the mythos alive.

Although the full album can be streamed on Necronomicon’s last.fm page (you can also listen to a few tracks on Nox Arcana’s website), I’ve done a little bit of research and collected the following videos that use the album’s tracks as musical background to display mythos-related slideshows. I’m still missing Eldritch Rites (track 10) and The Great Old Ones (track 21). If anyone finds them, please post them in the comments.
