For nearly 20 years now, this Chilean cult has built a commanding canon of eldritch death metal DARKNESS. From their early demos to later splits and especially their preceding three full-lengths - not least of which, 2014's critically acclaimed Baphomet Pan Shub-Niggurath - UNAUSSPRECHLICHEN KULT have explored the furthest reaches of primordial dread and ancient mysticism, all through pure 'n' authentic Metal of Death. But now, they've transcended all past accomplishments with the monolithic Keziah Lilith Medea (Chapter X). Across its taut, eight-song/39-minute duration, Keziah Lilith Medea (Chapter X) displays an UNAUSSPRECHLICHEN KULTEN at their most frighteningly feral and also most devilishly nuanced. The songs' successive slipstreaming surge creates a miasma of blunt-force trauma and hallucinogenic tension; any dynamic and detail the band wish to engage in is delivered with an almost unsettling, paradoxical grace. Keziah Lilith Medea (Chapter X) takes all the urgency 'n' ugliness of classic death metal and upends into the realm of high art. That assertion is further elucidated by the aforementioned booklet gracing the album, as well as its ominously striking cover. As if their bounty wasn't already overflowing, UNAUSSPRECHLICHEN KULTEN here deliver a work for the ages.
