Illbient music is an offshoot of the IDM movement, similar in style to
ambient, but far different in theme. Whereas ambient uses natural noises to represent almost a random pattern of music, illbient uses dissonant noises and dark, unsettling ("Ill") samples to create, at times, controlled chaos. Illbient ranges from very minimalistic to the rather complex, similar to other genres such as experimental hardcore and the later incarnations of IDM.
