Recording of Sten Hanson's Don't hesitate, do it right now. This work consists of 4 separate pieces: 'Che', 'The Glorious Desertion', 'Don't hesitate, do it right now', and 'Revolution'. This collection of pieces were inspired by the ADC (American Deserters Committee), a group of American soldiers that found sanctuary in Sweden after deserting the American army during the Vietnam war. The spoken text in this piece is sampled from a speech given by Che Guevara, a public figure who took part in Castro's revolution.

Recording of Coriún Aharonián's Que, spoken text performed by Armando Halty. All of the sound material, besides the spoken text, is electronically generated sounds.

Recording of Carlos Fariñas' and Sergio Barroso's Corales poema sonoro. This piece is excerpted from a show, "Dialogues," for band, instruments, images, and the public performed with Sergio Barroso in 1971. The sound poem is based on a montage of Cuban poems, which goes from a poetic enumeration of Cuban plants and trees to quotes from Macbeth and fragments of the Campaign Journal and other political narratives of José Martí (revolutionary, poet, founder of the Cuban Revolutionary Party, ideologist, pioneer of Latin strategic anti-imperialist thinking) written on the eve of his fall, fighting. Texts read, transformed concretely and electronically.

Recording of Antonio Mastrogiovanni's Cuauhtémoc. The work "Cuauhtémoc" is dedicated to this young Aztec king, who defended the city of Mexico against the Spanish conquerors commanded by Hernan Cortes. During the siege of this city, nine-tenths of the Aztec population was exterminated, and Cuauhtémoc himself was tortured and assassinated by Hernan Cortes. Three fragments of indigenous texts are used in the work: The first text is the one recited on the occasion of the birth of a Mexican child, and is mixed with the name Cuauhtemoc. The second text is a description of the Spanish army. The third text is a description of the city of Mexico after the cruel siege.

Recording of Gerardo Gandini's Los Proverbios. It contains the sounds of human voices only in a fairly simple and straightforward structure. The piece was the composer's first purely electroacoustic composition.

Recording of Eduardo Bértola's Tramos for tape. The piece was made from two sound sources: radio broadcasts and direct recordings of popular events. These materials were structured by simple juxtaposition excluding the mixes and any kind of development of the original sound. It is therefor a purely horizontal structure in which we note the union of fragments of hard edge, perfectly delimited, similar to that used in some works of North American Pop Art. In this way, Bértola expresses his own point of view on the cultural significance and the non-significance of radio mass media in the countries of Latin America.

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 …

Recording of Beatriz Ferreyra's "Echos" with vocals by Mercedes Cornu. The piece was made from the "destructuration" of four Latin American songs: two Argentinian and two Brazilian. Cornu uses a variety of vocal sounds (long and short sounds, breaths, coughs, etc.).

Recording of Alcides Lanza's Ekphonesis V. For actress-singer, lights, and electronic music. This work is rooted in the composer's continuing interest with "memories". This piece explores the "library" of memories, reflections, thoughts, and ideas, supposedly encountered if the soloist could enter the composer's brain. During this "tour of the brain," the "tourist" is confronted with the recollections of the composer, plus her own memories.

Recording of Joaquín Orellana's "Imagones d'une histoire en redondo (imposible a la equis)" for tape.

Recording of Joaquin Orellana Mejia's "Impossible a la x" ("Impossible to the X"). The piece raises the sonorous vision of a spiritual and violent situation, in which the primitive flows and their purity as a mimetic being and the "being children: are involved in clearly antithetical situations.

Recording of Ricardo Mandolini's Poema Reiterado using the voice of Leonardo Martinez reciting Mandolini's own poem "Palabras" in an electro-acoustic composition. All sound material are disengaged from the speech of the spoken text (Sprachkomposition) which embodies the idea of the ancient synthesis between text and music. Realized at the Studio of the Musikhochschule in Cologne, Germany in 1983.

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.

"Chicharra's" is an ode to the Spanish landscape and the men populating this landscape. Sounds of nature such as the breath of the wind, the rushing of the rain, the rustling of the sea carry life in themselves. Thus the rustling of "Chicharra's", the cicadas, their singing narrative was recorded as a set of precious voices. These voices were sent electronically to the strings and then turned into new sounds. This process is comparable to that of instrumental music where the violin bow is coated with coniferous resin to awaken sounds. Thus the buzzing of the fly on my microphone has been transformed into a kind of huge chorus of men. With the poet Schierbeek, I exchanged the Spanish landscapes that we saw and listened to. From there, the poems are born. Poems with the subject of the little donkey, famous because irreplaceable, men work the earth, the thirst, the red earth, the dark wine, the family life and the evenings of Spain. It is the beautiful voice of Lino Calle de Segovia that I chose as an interpreter and it is by kissing the glance, in memory, the mountains of Gadarama that I consider "Chicharra's" as a tribute to …
