Sioum is an instrumental trio based out of Chicago, Illinois. Formed in 2008, the band consists of 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.
