Lord Mantis are from the US and play Blackened Sludge Metal.
This is torturous, nihilistic Sludge with Blackened overtones and a deep, deep desire to do harm. They arm themselves with all kinds of sharp implements to rabidly experiment with in the search for the ultimate frenzied stab wound pattern. This manifests itself as 47 minutes of Blackened Sludge Metal with some noise components thrown in for good measure.
The songs are the aural equivalent of darkness made solid, with lurking dangers and scything evil hidden within and somehow free to move around in the impenetrable solidity of a corporeal inky black night.
Sounding like a more savage-than-normal Sludge band, Lord Mantis take vitriol to new heights and display a callous disregard for standard genre rules. Unlike some Sludge bands they also include blast beats and noise assaults in their armoury of nasty delights, and wield them with wanton brutality.
If you can handle the acerbic nature of the music then this is top of the league stuff. Depraved, vile, sinful and warped; this may be one of the best records of the year so far.
