Christian Fennesz (born 25 December 1962) is an Austrian guitarist and electronic music producer based in Vienna, Austria, often credited on albums simply as Fennesz. Christian Fennesz's trademark sound combines guitar playing with digital techniques like granular synthesis to make multilayered compositions that blend melody and conventional musical instruments with harsh, irregular glitch-influenced sounds and washes of white noise.. This style has been described as "Rock meets PowerBook".
