Alvin Lucier (born 1931) was an American composer. He was educated at Yale and Brandeis, where his teachers included Howard Boatwright, Arthur Berger, Irving Fine, and Harold Shapero. He also studied at the Berkshire Music Center (1958, 1959). After two years in Rome on a Fulbright Scholarship, Lucier joined the Brandeis faculty and became head of the electronic music studio. In 1970 he moved to Wesleyan University where he was appointed a professor of music at John Spencer Camp. He was a co-founder of the Sonic Arts Union, music director of the Viola Farber Dance Company (1972–1977) and a member of the DAAD Kunstlerprogramm in Berlin (1990). In the mid-1960s, Lucier began exploring sound environments, particularly sounds that "under normal circumstances would never reach our ears."
Using performers, electronics, instruments, architecture and found objects, he develops processes specially adapted to the phenomena he wants to investigate or reveal. In his works, he studies acoustic phenomena and auditory perception. He uses unusual configurations and experiments with technological devices in unconventional contexts. Some works use unusual sound sources, such as brain waves (Music for Solo Performer) or radio frequency emissions in the ionosphere (Sferics), while others focus on the physical properties of sound waves.
