Oval is the music project of German producer Markus Popp. Credited as a pioneering group of what came to be called glitch music, Oval’s early sound exists in a liminal space between ambient music, noise, experimental electronica, and minimal techno. Largely process based, Popp’s music relied on esoteric custom computer software as well as tactile techniques such as defacing CDs by scratching or writing on them to produce fractured, glitching sounds. These skipping, malfunctioning sounds defined Oval’s early aesthetic and inspired a legion of electronica and post-rock producers in the mid to late 1990s. Popp’s mid-90s work ranks as some of the most original and inspired abstract electronic music ever produced.
