Recording of Alcides Lanza's Sensors IV performed in 1984 by the McGill Concert Choir, conducted by Christopher Reynolds. The tape was realized at the Composer's studio (SHELAN Studio) and McGill University EMS in Montreal, QC, Canada. The piece explores different techniques of vocal wiring, especially the relationship of semantics, languages, and memory. The word "Memory" constitutes the entire text for the piece - using letter sound, recombinations of the word, and adding syllables from other languages that share similar etymology. Recording of the word "memories" -- Meg Sheppard's voice -- is used in the realization of the piece.

The subantarctic forests of South America are the world’s southernmost forested ecosystems. The birds have sung in these austral forests for millions of years; the Yahgan and Mapuche peoples have handed down their bird stories from generation to generation for hundreds of years. In Multi-ethnic Bird Guide of the Subantarctic Forests of South America, Ricardo Rozzi and his collaborators present a unique combination of bird guide and cultural ethnography. The bird songs, names and stories recorded on the CDs of the guide book includes entries on fifty bird species of southern Chile and Argentina, among them the Magellanic Woodpecker, Rufous-Legged Owl, Ringed Kingfisher, Buff-Necked Ibis, Giant Hummingbird, and Andean Condor. Each bird is named in Yahgan, Mapudungun, Spanish, English, and scientific nomenclature. As a whole, the recordings of this guide book express the voices of multiple species and indigenous, rural and urban cultures, whose lives are interwoven in the temperate forest region of South America.

Recording of Manuel Rocha Iturbide's Moin Mor. In music using concepts or ideas which belong to other domains is something that has been realized by composers for a long time. The central element of sound work is language, which is what characterizes a determinate culture. Language is made out of sound and meaning, out of syntax (rhythm) and out of words (signs) For this work English, Gaelic, and Spanish are used.

Recording of Carl Bergstrøm-Nielsen's "11 september." The text is from a document called "What is MIR?" which was sent out illegally in Chile in 1974 and from the appeal of MIR two years after the taking over by the junta, on September 11, 1975. A left-wing party, MIR stayed in Chile in order to contribute as efficiently as possible to the building of the opposition. Other sound material also includes sounds from a typewriter and a demonstration at Bastad, Sweden in September 1975 at a tennis match between Sweden and Chile with more than 4,000 participants. The text is taken in small excerpts from the document in Spanish, English, Swedish, Danish, French, Dutch, and Icelandic. The piece consists of three sections overlapping each other gradually, which shows the relationship between the spoken words and the immediate danger connected with that text. The first section "as a spontaneous statement," deals with the document at its direct background: the silence is broken, in spite of the danger connected with the writing, manifolding papers that criticize the politics and methods of the junta and discuss the strategy of the opposition. The second section deals with the document as a medium of discussion. At …
