What Passes For Survival is technical death metal seemingly created by Dadaists. Most of its songs are nonlinear splatters of amorphous riffs and centrifugal rhythms: “The Invisible Hand Holds a Whip” drops gooey layers of screams and grunts into the already disorienting mix, while the grindcore-flavored “Trash Talk Landfill” turns all of it cold and atonal. But Pyrrhon can also drop down a couple of gears, as on “Empty Tenement Spirit,” which is a bottomless pit of blackened clangs and plodding drums.
