Glitch

Glitch is a term used to describe a genre of experimental electronic music that emerged in the mid to late 1990s. The origins of the glitch aesthetic can be traced back to Luigi Russolo's Futurist manifesto The Art of Noises, the basis of noise music. In a Computer Music Journal article published in 2000, composer and writer Kim Cascone used the term post-digital to describe various experimentations associated with the glitch aesthetic. Glitch is characterized by a preoccupation with the sonic artifacts that can result from malfunctioning digital technology, such as those produced by bugs, crashes, system errors, hardware noise, CD skipping, and digital distortion. Cascone considers glitch to be a sub-genre of electronica.
