If the Glitch Art has a sound it would be composed by Venezuela-born producer Alejandro Ghersi known as ARCA. "You can hear conventional musicality inside of his tracks—melodies, chord changes—but rather than being fixed on paper, they are always in flux. Individual notes twitch and vibrate, refusing to stay with a single pitch; rapidly shifting clusters hint at proper chords without ever quite committing to them; tempos speed up and slow down according to whims rather than the grid of a timeline. Arca’s deeply organic machine music is defined by Ghersi’s ability to find grace in imperfection." Mark Richardson. Pre-order ARCA's "Mutant" on iTunes or listen and watch few bits below
