There are probably dozens of ways to categorize the instrumental music of Sannhet. Postrock, postmetal, postwhatever, the Brooklyn trio makes eerie, foreboding music with a blackish metal tint that aids in differentiating them from the more hush-hush-loud fare of our present-day instrumental and postrock heavy hitters (Explosions in the Sky, Sigur Ros, Mogwai, etc). On February 19, Sannhet is releasing the full-length Known Flood through Sacrament Music—the brand-new label formed by the dudes who run Brooklyn metal venue Saint Vitus. Today’s 12 O’Clock Track is the album’s opening track, “Absecon Isle.”
