OBSOLETE THEORYs music can be identified as an Atmospheric Black Metal rich of hints from Doom, Death and Post-Black Metal. "Mudness" is the bands debut album and pushes the bands vision of dark music to new levels. It is a manifesto of heaviness, depth & atmosphere everything into a magnificent Doomish Black Metal. With five long, complex and full of pathos songs, they create an opus of emotional sonorities ranging from different facets of music and firmly displaying OBSOLETE THEORY's broad range of influences like Behemoth, Agalloch, Katatonia, Solstafir, Alcest, Enslaved, Opeth with an already accomplished personality.
