Atheos is a ferocious new collection from Rotkeller, which sees the Swiss electronic duo (Laurent Schmidhausler and Federico Sutera) double-down on the brooding energy of their previous releases with a renewed intensity-fusing bold electronic experimentalism to dense, maximalist techno.

Whether on the slow-burn immensity of opener "SW", the monolithic, doom-laden expanses of "Malz" or the spellbinding surge of "17. October", Atheos showcases a dark melodic complexity from the duo-in part brought on by the use of both digital and analog recording techniques.

While the mesmeric, choral melancholia of EP closer "Godless"-its eerie and beguiling textures echoing all that has preceded it-offers-up ominously open-ended ending; solidifying Atheos as Rotkeller's most atmospheric and cohesive work to-date.

As if that wasn't enough, EOMAC (Stroboscopic Artefacts, Killekill, Trilogy Tapes, Bedouin) caps Atheos off in style, with a savage edit of "17. October". The remix that pushing Rotkeller's original track into new rhythmical directions-the glassy rhythms splintering like shards of light across an eternally eclipsed landscape.

Set for release in both physical and digital formats on May 5th, Atheos marks Rotkeller's first EP for Swiss-based record company Threnes (which takes its name from the Greek word for funeral lament) and are a label dedicated to the release of tenebrous electronica and techno.[info sheet from distr.]
