Edgard Varèse, the pioneering composer of electronic music, formed the subject of a major exhibition in Basel in 2006; it displayed many previously unknown documents from the composer's estate, including manuscripts, letters, and other material. This volume contains detailed commentaries on all the items on display, as well as thirty-two essays by leading authors from Europe and America. Varèse's life and music are discussed under the following headings: Influences - Points of Orientation; Conductor and Initiator in New York; Probing Uncharted Territory; Impact and Reception. Many previously unknown documents from the composer's estate, recently acquired by the Paul Sacher Foundation, form the basis of a nuanced picture of Varèse's life, musical thought, and compositional output. The book is lavishly illustrated with facsimiles of manuscripts, letters, and other documents from the composer's collection, as well as reproductions of paintings, drawings and sculpture documenting Varèse's close ties to the visual arts.
