Sioum is an instrumental trio based out of Chicago, Illinois. Formed in 2008, the band consists of brothers Dorian Zdrinc (guitar), Arthur Zdrinc (drums) and Kevin Clark (keys). They often draw inspiration from film, video games, and most frequently, emotion itself. Post-metal, as well as progressive influence are often noted, although occasionally, many broad (and unusual) influences, such as contemporary classical and chiptune, can be heard.

Almost six years after Sioum’s debut LP, in May of 2016 the group released their second full-length album Yet Further. It was recorded and engineered by Greg Norman (Russian Circles, Godspeed You! Black Emperor, Pelican.) Whereas I Am Mortal was based mainly on fictional stories and imagery, the music of Yet Further serves more as artifacts that reflect and convey the personal tribulation, hopes, and fears experienced after their first album was released. The music maintained a similar cinematic and emotional core, but with more content, variation, and complexity throughout each song. A noticeably more progressive influence could also be heard, with heavier exploration of distortion passages.
