UbuWeb's Sound section provides a survey of sound art from the early 20th century to current works. It includes genres such as Dadaism, Futurism, musique concrete, electronic music, Fluxus, Beat sound works, minimalism, performance art, sampling, and digital glitch works. The artists are listed alphabetically rather than by category. UbuWeb aims to make obscure and difficult to find sound works freely available in MP3 format while also promoting currently available works by streaming them from small labels.
