Sannhet is going to be releasing Revisionist on Mar. 3 via The Flenser and up to the moment I started writing this I had no idea they even existed. Apparently the band's first album, Known Flood, made some waves and after one listen through the song "Revisionist" I can see why. Sannhet manages to compose instrumental music that never once feels like it needs vocals or something else besides what's going on already. It's just solid, sludgy, noisy, disgusting black-ish metal that fears no prog.
Jam it and become a believer.
