Originally coined by minimal artist
Steve Roden, lowercase is an extreme form of
ambient
minimalism in which very quiet sounds bookend long
stretches of silence. Roden started the movement with an
album entitled Forms of Paper, in which he made
recordings of himself handling paper in various ways. These
recordings were actually commissioned by the
Hollywood branch of the Los Angeles Public Library.
Many artists have contributed to the lowercase movement, including electronic music pioneer and educator Kim Cascone, Tetsu Inoue and Bernhard Gunter.
Some of the labels that publish lowercase music include Trente Oiseaux, 12k, and raster-noton, which features famed composer Ryuichi Sakamoto in collaboration with Carsten Nicolai, a.k.a. Alva Noto.
