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 Royon Le Mée's "Troisième doxologie Saint Sébastien" ("Third Doxology Saint Sebastian"). The piece is an electronic postlude in three stanzas.

Recording of Jarmo Sermilä's "St Henry's Tribe Memorial Anthem" for tape.

Recording of Bohdan Mazurek's 6 electronic preludes for tape.

Recording of Martin Sierek's Quadratwellenklangwurst. The piece is based on micro-intervals through the use of square-wave oscillations. These exact intervals were only achievable with a digital rectangle generator. In the composition, the higher pitched parts of the two harmonies are fed to the cohesive basic tones and a whole sound becomes a glittering sound spectacle. The intervals and the number of individual rectangles constantly increase during the composition and generate acoustic phenomena and end in a cluster. The only "ordinary" intervals, a big second after and then a minor third, are just decoration.

Recording of Stephen Montague's Scythia for electronic tape. Scythia was a region of Central Eurasia in classical antiquity encompassing parts of Eastern Europe east of the Vistula River and Central Asia, with the eastern edges of the region vaguely defined by the Greeks. It was thought of as the great land of education. It was also the place where Prometheus gave fire to man and where he was confined to be tortured by the gods for this. Every day an eagle came and tore out his liver and every day he endured.

Recording of Klaus Röder's kristallisation I. The material of this piece are tape recordings of triads played with the guitar. 26 tape loops contented 4 triads each on 4 different channels. The pitches were chosen such as to build a cluster with the extent of one octave by simultaneous reproduction of all 4 channels of one loop. The loops differed in pitch and were arranged in chromatic order so that the 'lowest' loop extended from E1 to Dis1 and the 'highest' one from E1 to Dis2. Then from the tape loops special parts were copied to another tape in a fixed order. By taking either the front or the back part of a tape loop variations in tone color and volume could be made ( loud, clear, hard-swinging: font of the loop; silent, dark, smooth-swinging: back of the loop). The copied parts were cut into pieces according to their duration of tone and then they were put together again. Sequence, color and duration of the tones were provided by the score. Tone color and duration change from tone to tone so that there is a fluctuating impression.The whole tape consists of several thousands of cut pieces that were stuck together. …

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 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

Recording of Werner Kaegi's Conversations: Partie 2: Automne.

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 Jan Oleszkowicz's Spasme for tape.

Recording of Elżbieta Sikora's La Tête d'Orphée II. the piece is based on the story of Orpheus returning from hell to find Euridice. Commissioned by the Experimental Studio at the Polish Radio in Warsaw in 1981 and was composed in the same studio with the technical collaboration of Barbara Okon-Makowska. It was premiered during the "Warsaw Autumn" festival in September 1981.

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

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 Robert Rowe's "Spattering... A Shower." This piece of computer music focuses on the organization of sound and the process of adopting the medium of a digital computer to produce music compositions.

Recording of Alireza Mashayeki's Polyphonie.

Recording of Ivan Patachich's Ludi Spaziali for piano and tape performed by Erzsébet Tusa (piano) and sound engineered by Peter Winkler at the studio of the Hungarian Radio. The purpose of the piece was to widen the sound and technical possibilities of the piano through means of electro-acoustics by modulations of piano sounds and by synthetic sounds and spatial movements.

Recording of Gabriel Poulard's Blueberry for tape. The title refers to the name of a cartoon character. The piece was realized at Groupe de Musique Expérimentale de Bourges (GMEB).

Recording of Arthur Kreiger's "Variations on a theme by Davidovsky" for tape. It uses the first 10 measures of Nario Davidovsky's "Synchronisms no. 6 for piano and electronic sounds" (1970) as a thematic subject. The theme appears orchestrated for tape alone approximately 45 seconds into the composition. It is preceded by a short introduction and is followed by a series of variations. These variations differ widely and explore an extensive palette of electronic sounds. The present version is a two-track reduction of a four-track original.

Recording of Clifford Taylor's "Blendings" performed by Clifford Taylor, clarinet. The piece focuses primarily on combining various registral sounds of the clarinet with synthesized sounds of a variety of timbres.

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 Ulrich Suesse's Oboe. There are basically two considerations for the application of tape 2 :1) It can be a source of inspiration during the performance and/or 2) It can be a source for "overloading" the piece, bringing it near the breaking point. Its actual application (or non application) depends on the intention of the performer. An existing version of tape 2 can be used or a new, unique, completely unknown version can be created: a copy of tape 1 is to be used as the source material; it should be spliced apart, rearranged and mixed "BLINDY", yet with respect to the following 6 categories: a) SOUNDLAYERS are superimposed pieces of pieces of tape (dubbing); b) STINGS are anything with crescendo (to be realized at the performance through volume control); c) HIGH NOISES are pieces of tape at doubled, tripled playback speed with or without hiss; d) POINTILLISM is interjecting anything in short attacks (for instance through starting and stopping the tape); e) WAVES are done through various glissando-like speed manipulations; f) LOW NOISES are pieces of tape at lower playback speed with or without reverberation.

Recording of Miloš Petrović's Aw/wW ("Anton with-without Webern") for tape, interpreted by Ruža Petrović, Paul Pignon, and Miloš Petrović. Petrović uses the sound and structure in Anton Webern's works as a way of broadening the sound media in his own work. He places this work in a space defined by primal elements of different media, which allows for a greater number of operations on the speech-gesture relationship, while contributing to the cohesiveness of the result. Magnetic tape-transfected parts of Webern's composition, purely electroacoustic segments and short quotes from the composer's work. The tape was made in the electronic studio pf Belgrade Radio-Television. The work was written and presented first in 1981.
