Glitch is a contemporary genre that relies on the splicing of small samples of music with beats made from clicks, scratches and other sounds of technology gone wrong.
The first glitch album is recognized as Oval's Wohnton (1993); Oval is a German electronic
band who create their sound with hi tech computer programs but also by writing on CDs with felt pens (they are sampled on Bjork's Vespertine album). The early 90s also produced Kid 606, Autechre and many more.
Labradford lean towards an ambient glitch sound, while the Glitch Mob use the techniques
with hip-hop. The most comprehensive series of glitch sounds can be found on Clicks and Cuts (Volumes 1 to 4, 2001-2004).
