Noise rock is a genre of music that emerged in the late 1970s and early 1980s, characterized by its use of distorted guitars, dissonant chords, and abrasive sound textures. The term "noise" refers to both the harsh, chaotic sounds created by the instruments as well as the overall aesthetic of the genre, which often features aggressive lyrics and an energetic, confrontational performance style. Noise rock is closely associated with punk rock and post-punk, but also draws from experimental music, industrial music, and other avant-garde genres. Some notable noise rock bands include Sonic Youth, The Jesus Lizard, and Dinosaur Jr.
