It is important to realize that demos were once demonstrations of talent that were circulated by record labels and eventually fans of unpolished heavy metal. the spectacle of talent despite production limitations and the promise of potential is what makes demos so exciting. Today, the idea of demo could just be a permanent state for people who never have any intention on making anything else. This is fine but initial demos from new bands still have excitement and zeal s they once did especially when the band plays colossal death metal.
Thanamagus still has yet to get a Metal Archives page and their Last.fm count is currently at 0. If one wanted a band cut from the side of a mountain before any refinery techniques, then this is the time to look. With looming riffs and a wild black and white cover this is the perfect place to start if you wanted raw and unfiltered death that may or maybe be greymarket and may or may not be anything beyond this demo. People who are into this type of stuff, however, are into these types of quirks and love the shit out of this type of stuff.
