Sometimes, the hardest thing about working in music media is receiving an advanced copy of a mind-blowing album and then being forced to keep mum until the album's wide release. We've been sitting on Known Flood for a few weeks now, and not being able to blab about it to anyone who appreciates a good eardrum pounding was becoming unbearable.Lucky for us (and you), today's the day that the newly-minted label Sacrament Records has decided to give up their V card to Brooklyn post-metal trio , so please allow us to word vomit accolades all over your nice shirt. Known Flood is 45 minutes of unrelenting, expertly crafted instrumental hardcore with something to prove. Intimidated? You should be. Hit play below if you're ready to be ravaged, and order the album here.SANNHET is playing an unmissable album release show this Friday at Saint Vitus (whose owners also herald the label) in Greenpoint with deafheaven, Cleanteeth, and Theologian. Grab tickets for that here.
