"Not Of This Earth" is another prime example of what this band is about. The riffs are slow, heavy and crushing as the vocals penetrate the rest of the music with that downer feel. Toward the end of the song, the drums change patterns and the guitars forge into another catchy groove riff. The bass becomes really distorted when compared with the rest of the music. The ending lead blends right in with the rest of the music.

"The Gods And The Dead" is another awesome example of how doom metal should be played. The riffs are atmospheric and heavy as usual. The drumming is loud and powerful as the snare hits and the crushing symbols mix perfectly with each other. The vocal work is clear and thundering, yet still fits in very well with the rest of the music.

"Under The Influence Of The Moon" is probably the weakest track on here, but is still pretty good. The guitar distortion is really heavy and slow, while the drummer nails his snare and his punishes his symbols. The vocal work is powerful as usual and works well with the rest of the music. The same riff continues for a majority of the fourteen minute monolith until it ends with the fading distortion.

The Purity Of Oblivion is a damn good demo. It will be pretty interesting to hear the future material of Salt Of The Earth. The Purity Of Oblivion is a great start to what may become metal stardom.
