SiJ is an Ukrainian dark ambient/drone project created by Vladislav Sikach in March 2011 in attempt to develop unique sound combined with various industrial features mostly in sombre dark ambient way. For this reason, SiJ uses great number of instruments such as various guitars, drums and synthetizers as well as handmade mechanical or electromachanical sound devices. Recently SiJ started to use field recordings made in various places from urban streets to abandoned military and industrial facilities. Another tools for creating SiJ's soundscapes are VST-technologies, digital sound processing and CSound sound-synthesizing programming language. SiJ used to cooperate with many ambient, dark ambient, drone, industrial and noise projects as well as with people who work only with field recordings.
