Undercurrents: The Hidden Wiring of Modern Music by the Wire (2002) - Rob Young
In a series of essays by some of the best music writers of our time,
Undercurrents identifies the key concepts and underlying themes that have been hardwired into the modern era's most radical musics, ever since Thomas Edison invented the record player. The phonograph, electronics, chance operations, Futurism, Surrealism, the civil rights movement, noise, alternative tuning systems and market forces have all redrawn the map of contemporary sound. Undercurrents tracks these seismic shifts across a wide range of music including modern composition, free jazz, experimental rock and pop, Industrial, ethnic music, Techno and electronica, and looks at the extraordinary innovations and invented instruments that have passed into obscurity.
