Recording of Coriún Aharonián's "Esos silencios" ("Those silences"). "Esos silencios" are the silences of our daily vital experience of the seventies in almost all Latin America. "We do not desire them, but they surround us always, until we finally succeed in breaking them," Aharonián wrote. It exclusively uses materials of microphonic origin. Some of the sounds have been made with instruments constructed in Guatemala by Joaqu’n Orellana. The decision to bring to life the piece at that historic moment was convergent with the emotional experience that the pricking edges of the delicate drawings by the Argentinian-Uruguayan Mar’a Carmen Portela and the gagged yell of the dramatic paintings by the Uruguayan Hilda Lopez. In Esos silencios there is a will to establish large, apparently static, areas, with latent tensions, in a structure of full hard edges, almost without the concession of transitions.The piece was originally composed in 1978 and was revised in 1981. It was realized in Elac, the studio of Montevideo. The materials of departure have been produced by the author

Recording of Jon Appleton's Sashasonjon for synthesizer. In memorium Alexander Walden (26 December 1896-4 February 1981).

Recording of Daniel Arfib's "L'imminence de la lumière" ("The imminence of light"). It is one of the several pieces of computer music Arfib created as a researcher and composer.

Recording of Durand Begault's Funny Death. "The composition invites the listener to consider the movement of sounds and the synthetic space which they move through. Funny Death should be listened to in darkness so that concentration of the movement may be facilitated." - Durand Begault

Spaces first, they coexist, they pass from one to the other, mix, then, a break, the dimension is different: we have entered the micromonds of the sound that develop, as if the spaces had become immense -

Recording of Nicolae Brînduș's Kitsch_N for clarinet, saxophones, Hungarian folk instruments, and tape. It is an instrumental theatre subscribed to the preoccupation of the author with controlling randomness in a musical action where the sound, attitude and stage gestures are structurally corroborated widening the domain of the performance. It is the second piece of a cycle named Vagues where the author develops similar stochastic principles of composition.

Recording of Nicolae Brînduș's Match - Monody I & Polyphony IV. It is a version dedicated to the Ensemble "Ars Nova" from Cluj Ð Romanian and based on collages of traditional folk dances from Romania's northern area of Maramures and ancestral laments from the regions of Banat and Oltenia. The final tape was re-positioned in the frame of the performers' controlled improvisation live which follows the same principles of composition. It became a sort of an ancestral memento to the momentary performing act. The music on the tape evolves from the natural sound of the folkloric sources, quoted as such, to its multiple subsequent electronic transformations, coming back to the same folkloric quotes in their natural sound at the end. All the process of transformations represent the pulsing and not pulsing metric type of musical activity (tempo strie and tempo lisse so as described by Pierre Boulez).

Recording of Rodolfo Caesar's Tremola impressao. This piece is a mix of disparate languages: instrumental music, sounds of nature and electroacoustic music, resulting in a different kind of electroacoustic music. The material originates from earlier works, not always Caesar's, but manipulated to make it different. He tried to make useful the sounds that were condemned trash; without any comparison with "Fontana Mix" by John Cage

A recording of John Celona's Music in Circular Motions. "Music in circular motions" was produced using DISTRA, a real-time polyphonic 4-channel spatial movement computer performance program created by the composer for a New England Digital Synthesizer at the University of Victoria, British Columbia. The control language for DISREA is called "Moxie, written by Doug Collinge, and is a set of XPL procedures which deal with events in real-time. In DISTRA, the composer uses a keyboard and CRT terminal through which programmable controls are utilized during composing and performing. Pitch (available in equal - and 31- tone temperament as well as just intonation) is input through the keyboard and orchestrated in real-time with varieties and variations of spatial movement, multi-segment envelopes, wave shaping FM, volume controls, filter effects, delays, and tempo changes. In addition, several automated routines are available procuring program switching of spatial distribution patterns, volume cycles, sequential execution of envelop arrays, modulation ration and index arrangements, Changes may be input on a micro-level (e.g., replacing c:m rations or selecting new envelopes during ongoing sound events) or on a macro-level where larger compositional contexts are manipulated. Thus, the composer operates synchronously on three interactive levels: performer (playing instruments-conductor (shaping and …

Recording of Fernando Condon-Garcia's Suiana Wanka for tape. This work collects and develops independently the materials of a music scene for Peter Shafer work "The Royal Hunt of the Sun". It is based exclusively on sound recordings of various Latin American instruments such as the Indian flute, pincuyos, sicus, tarkas, mohecenos, various kinds of percussion, etc., to which are added, during some passages, instruments from European culture (organ, flute, bass). The original sound was made in a professional studio, and the final realization was made in ELAC, a small Montevideo studio, with the technical assistance of Carlos Da Silveira.

Recording of Frank Corcoran's "Balthasar's Traum" performed at the Electronic Studio of the Berlin Technical University in close cooperation with Folkmar Hein. The work is based on an idea of a short story by Jorge Luis Borge and the Gospel of St. Mark about Balthasar Espinosa, a man who becomes involved with the Gutres people of Pampa and eventually dies by being hanged on a cross by the same people with whom he was so fascinated. It takes place in the great plains of the Pampa where Baltasar Espinosa is invited to his friend's ranch. To escape the monotony of continuous rain, he begins every night to read aloud to the fascinated Gutres people. They ask for him to reread the Gospel of St. Mark. Mysterious things begin happening during the dark days -- Baltasar cures an animal through 20th century means, something the Gutres have never seen before. The rain eventually stops. That night a virgin Gutre girl visits Baltasar's bed. The next day, he reads the Gospel to the Gutres for the last time. They then ask Baltasar, who is not a believer, if even those who crucified the Savior can receive salvation. They ask for his blessing, …

The Snake Oil Symphony (a metaphor for capitalist social relations, was composed in 1981. The first three "movements" of the Symphony establish the basic themes, along with an underlying rhythmic structure that crops up again and again throughout, as the tempo and pitch of phrases are used to create a sort of melody. Part One presents the surface reality of society as an endless movement of buying and selling, through the use of clips from a sales instruction talk, ads and so on. Woven through this is an ironic verbal-musical motif: "Now you can have this amazing new symphony, right in your own home," (which parodies cheap TV commercials), with piano notes underscoring the spoken pitches. The word "symphony" refers not only to a single work of art, but in the greater sense to "a mighty symphony of prosperity" (i.e. present social and cultural institutions). With the same phrase the composer is also letting the listener know that he knows his own work, too, is a commodity on the culture market. Part Two is built around a multiple pun on the words "alien" and "alienation." "Alienation" originally meant "sale." Marx used the terms to describe the way people give up …

Recording of Yves Daoust's La gamme. This is a work for electronics.

Recording of Joe Davidow's "Music for two flutes and tape." All of the sound material for the tape was originally played on the flute. The studio processing has has the aim of enhancing the inner harmonics and enriching the more obscure instrument sounds, bringing them to the forefront in inter-structural relation to the two live flutes. Breath, which is the original source of all the sound in the work, is itself an intricate part of the sound color relationship, together forming a structure of interweaving live and processed flutes, counter posing the real and surreal.

Recording of Roberto Doati's "Una pulce da sabbia" ("A Sand Flea") for tape. This work utilizes a timbre space built on three dimensions: spectral energy distribution, spectral fluctuation, and high frequency energy which precedes the full attack of the tone. The sound synthesis models used are simple waveshaping and FM. The overall structure of the composition is generated by the projection on a two-dimensional space with frequency as the ordinate and time as the abscisa, of an architectural structure plan. Doati achieved the desired temporal extension by means of the ‘slowing perspective’ technique. As regards the choice and the treatment of the macrostructure and its internal organization, they depend exclusively on the compositional parameters: symmetry, regularity, direction, velocity, focus and flight point (terms borrowed from the visual arts world). The internal temporal organization of the polyphonic rhythmic structures that make up the macrostructure is given by the position of the focus. This one is determined too by the parameters above mentioned. Each structure takes the timbre that occupies the corresponding position in the timbre space. It was realized at the facilities of the Centro di Sonologia Computazionale at the University of Padova.

Recording of Bertand Dubedout's "Aux lampions" ("To the lanterns"). Lampions are small oil lamps, formerly popular as a carriage light. It is a concrete piece in three movements: "Bal convexe" ("Convex ball"), "Le cocher" ("The coachman"), and "Sous les planches" ("Under the boards"). For writers like Bulgakov, Gogol, and Chekhov, the ball scene is often a story of action, tragedy, or desperation; the ball can ruin an existence or bring hope. Delight, delusion, and loneliness are the multiple stigmata of the ball. The sound materials of the piece are all concrete sounds that are based on reality. The sound forms escape any precedence, combining to create images of incongruous weddings like in an agitated dream.

Recording of László Dubrovay's Reszere for percussion and tape.

Recording of Will Eisma's "Le grand silence d'un seul oiseau" ("The great silence of a single bird") for tape. During World War II, a network of 40,000 km of trenches crossed South Flanders and the North of France. Still today, there remains part of these trenches as a long underground tunnel somewhere around Metz and Verdun. The composition represents an imaginary underground journey from Calais to the Swiss border, through the infernal moles, in the gloomy and frightening obscurity of this absurd war. The poem of Ab Van Eyk tells of these horrors: "Someone walks forward, slowly spitting out his lungs, while a bird pass near me, the gas ......... The night shows fiery angels, among the lights of the "no man's land "; until the twilight silence arrives, the great silence of a only bird, just before sunrise raspberry color." The piece was composed and realized in the studio Five Roses in April 1981.

Recording of Claude Fatus's Voyager. Using the possibilities of the MIDIM7 system, this realization highlights two classes of sounds that are different in nature: those of the vowel type (simple relation between harmonic partials) and those of the fricative type (complex relation). Use is made of the difference in amplitude and phase as well as the reverberation on identical signals to create a different displacement and localization of the sound event in the speaker space. The whole piece is articulated on the juxtaposition of 5 VOSIM queues of increasing duration which, each, generates 3 other queues at different synchronization.

Recording of Patrick Fleury's Reflux. This piece was completely generated on the New England Digital System at Marseilles. Then, the composer transformed all the basic materials in the analogy-mixing studio at IPEM de Gent. Studio of realisation: Groupe de Musique Experimentale de Marseille for the generation on New England Digital System. Institute voor Psychoacustica en Elektronische Musiek for all treatments and mixing.

Looking for the fusion between the path and the band "le Tombeau de W.Byrd" attempts to contrast the instrumental character of Byrd's pieces with the various identities of electroacoustic music. Thus, the two writings do not meet, they coexist: one is a point of definition of the other, one is necessary for the existence of the other. Separated by small harpsichord pieces from William Byrd's "Battle", five electroacoustic sequences offer a journey into the world of loop music. Would "Tombeau de William Byrd" not be the opposite of mixed music?

Recording of Bernard Gagnon's Dictée for tape. The majority of the material was executed in real time. The instruments used are voice, a pencil, and also a few oscillator sounds. An oscillator provided a wave that was delayed by tape, and then turned into a voltage to modulate the early sound: a self-modulating delay loop. The piece is a reflection on the anxiety of first learning to write as well as on the degrees of the distances of the writing. The dictation comes from a loudspeaker, while the writer's reactions and his perception of the loudspeaker are captured on the other channel using a microphone. We hear in succession and by degrees of writing: 1. The dictation only. 2. The presence of someone who listens. This presence is signaled by a microphone feedback on the other channel and then a cough. It is good here to specify that the feedback effects are voluntary and controlled. 3. The message changes channel because it becomes the pencil noise of the writer. 4. The transformations that the message undergoes as well as the act of writing of the character who, one realizes, dictates himself. 5. Echoes of his reactions, a kind of subjective …

Recording of Xavier Garcia's "Pourquoi t'as jeté ta pantoufle?" ("Why did you throw your slipper?"). Garcia asks the listener to do two things when listening to the piece: to pervert your listening and to find drama where there is none. To is done through both concrete listening (identifying the surrounding sound world, hearing external noise and understanding the "clues" -- this sound is read as the index of a causality.) and abstract "reduced" listening (listening to the thing for itself, detached from its causal context -- a sounds characteristics, height, dynamics, articulations). Therefore, in the piece there is always a constant misunderstanding between listening to the counterpoint of different "ways" and listening to a casual reference anecdote. In addition, the ambiguity lies in the fact that the sound data that constitutes the anecdotal reference is also one of the melodic paths of counterpoint. The piece was realized in the G.R.M. studios in February and March 1981.
