Sioum is a progressive instrumental band from Chicago. The trio often draws inspiration from dreams, movies, video games, and emotion itself. 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.
