Oval
Oval is an electronic music group founded in Germany in 1991. The band's original members were Markus Popp, Sebastian Oschatz, and Frank Metzger, although Oschatz and Metzger left the group in 1995. All three are regarded as pioneers of glitch, a genre of music that embraces the sound of damaged audio produced by the failure of digital equipment. Disdaining the use of synthesizers, Oval instead deliberately mutilated CDs by writing on them with felt pens, then processed the palette of fragmented sounds to create a very rhythmic electronic style.
