No wave was an avant-garde music genre and visual art scene which emerged in the late 1970s in Downtown New York City. The term was a pun based on the rejection of commercial new wave music. Reacting against punk rock's recycling of rock and roll clichés, no wave musicians instead experimented with noise, dissonance, and atonality, as well as non-rock genres like free jazz, funk, and disco. The scene often reflected an abrasive, confrontational, and nihilistic world view.

Noise music is a genre of music that is characterised by the expressive use of noise. This type of music tends to challenge the distinction that is made in conventional musical practices between musical and non-musical sound. Noise music includes a wide range of musical styles and sound-based creative practices that feature noise as a primary aspect.
