The Penumbra is known as the complete, or perfect, shadow of an opaque body, such as a planet, where the direct light from the source of illumination is completely cut off.  Penumbra is also known as a phantom or shadowy apparition; someone or something that is not physically present.  A ghost, a spectral image.

This album captures the feel of the Penumbra, featuring haunting melodies with a classical influence.  Great for haunted attractions, horror websites, films, film trailers, or just creeping yourself out; this album is another amazing record from the masters of horror sounds and music.  Audio Zombie's "Penumbra" features 13 tracks and over 50 minutes of music.
