Recording of Ákos Rozman's Impulsioni I-III. Impulsioni I-III was realized at the electronic music studio EMS in Stockholm. The three etudes are built on synthetic sound material. There is a strong influence from The Basilica di san Clemente in Rome and a sense of Good and Evil, a theme that was to remain important all through Rózmann’s life.

Recording of Karel Goeyvaerts's Op Acht Paarden Wedden.

Recording of Lucien Goethals's Studie VIIb. Six groups of 24 frequencies, chosen in the tempered system, undergo 12 transformations of amplitude and duration. The succession of the 72 variants of the basic groups is determined by the random element of the programmer, by means of which this study was carried out. During the production, the multiple possibilities of this programmer significantly contributed to enriching the sound result, which the composer decided to distinguish between the compositional level, now called Studie VIIb, and the new version, resulting from the achievement.

Recording of Eugeniusz Rudnik's Ready Made. This piece constitutes a palette of various sounds arranged in different ways. In the years 1970-72 I had collected various sounds, mainly short episodes (4-5 sec). Recorded on a magnetic tape. The decision of which were the best acoustic events worthy of re-use was based on their contrast with usual sounds. The second criterion of choice was based on links between the history of the recording studio and the music itself. According to these principles the composer assembled more or less 2 hours of musical material, which afterwards was several times selected and organized in order to be able to build the whole of this piece. The event is exposed in the time essential for human perception of its voice and afterwards should disappear to make way for another. Nothing is taken back. It's a collage without quotes. The whole piece could be summed up in a single sentence: "the goal of all this being to approach sea fish towards mountain regions". The rustles are designed in a form of pastiche to imitate the style of certain pieces composed in the early days of electronic music. "Ready made" (the title) is a term created …

Recording of Dubravko Detoni's Phonomorphia 1. Synthetic music based on the elements of the human voice and percussion. Two fundamental layers moving from positions of opposite heights, meet in the middle and separate starting in different directions. This electronic study was carried out at the Experimental Studio of Polish Radio in Warsaw.

Recording of Nicole Lachartre's Mordre La Terre Vivante. In the first part, a large number of quasi-linear paths intertwine to create a semi-fluid mass that is sometimes even almost amorphous. This is followed by a section worked into a precisely sculpted dynamic profile and contrasting rhythmic formulas are introduced at times by a wide variety of instruments including various percussions over which an almost classical solo voice hovers. Then the strict rhythmic formulas are temporarily destroyed by aggressive material introduced in overprinting whose pitches and durations have been determined stochastically.

Recording of Boguslaw Schaeffer's Theme: Electronic Music (Synthistory).Synthistory was produced in the Radio Belgrade Electronic studio on a Synthi 100 in close collaboration with Paul Pignon. This work was produced in April-May after working on Music for tape. Synthistory is composed in three parts, using the sequencer for most parameters. The two short outer parts are similar in material and special distribution, but differ in many other aspects. The middle part is much longer and composed with very complex initial material. The whole work is planned and composed for four channels, subsequently mixed down to a stereo tape but variation of stereo position of each channel according a predetermined plan.

Recording of Charles Dodge's Speech Song. The first movement, A man sitting in the cafeteria; second movement, The days are ahead; third movement, When I am with you; Fourth movement, He destroyed her image. Speech Songs was created at the Bell Laboratories in 1972 by composer Charles Dodge using a speech synthesis system of Joseph Olive. The four short Poems are by the distinguished American poet, Mark Strand. The songs, especially as articulated by the computer-synthesized voice, are ironic, surrealistic and humorous. One may trace the improvements in the quality of the computer-synthesized voice in the course of the four songs.

Recording of Ákos Rozman's Impulsioni, the collective title of three works (Impulsioni I-III) realized at the electronic music studio EMS in Stockholm. The three etudes are built on synthetic sound material. There is a strong influence from The Basilica di san Clemente in Rome and a sense of Good and Evil. In 1981, he made Impulsioni I-IV adding on a fourth part containing sounds from sparrows, among other things.

This was conceived in 1973 and finalized in this form in 1983 (at Electroacoustic Music Studious from Gent and Bucharest). In 1985 it received the International Confederation of Electroacoustic Music (C.I M.E.) prize. Natural – Cultural is a spectral archetypal music. It suggests the Bib Bang, the initial Explosion, the Cosmic Birth of Universe (of Galaxies), of Nature, the Creation Moments in 6 biblical days, the appearance of the 4 existing kingdoms: mineral, vegetal, animal (insects, birds, animals) and human. This process develops on an egg spiral (archetypal form) which begins on central sound G (the 6-th harmonic) in a c o n t i n u o u s evolution to acute and deep searching for acute E (the 80-th harmonic) and deep D, the FUNDAMENTAL sound. We witness the growth of a “sonorous tree”, the “life tree”, the Archetype of the archetypes, which yields till the end (in the 7-th day), cultural “fruits”, a s c e n d a n t melodies played by a piano. This work will be broadcasted into vast spaces (wit many loudspeakers), as ambient music, on the top of a mounting or at see shore, or inside an astronomic observer at sunrise …

Recording of Karel Goeyvaerts's Op Acht Paarden Wedden. The title can be translated as "Betting Eight Horses."

Recording of Lucien Goethals's Studie 7b. Six groups of 24 frequencies, chosen in the temperate system, undergo 12 transformations of amplitude and duration. The succession of the 72 variants of the basic groups is determined by the random element of the programmer, by means of which this study was carried out. During the realization, the multiple possibilities of this programmer contributed significantly to enrich the sound result. The composer decided to make the distinction between the compositional plan, called "Study VIIa", and the new version, resulting from the production.

Recording of Zoltán Pongrácz's Zoophonia for two channel tape. The sound material consists of thirty different animal sounds - including dolphin, fish for the Black Sea, monkey, dog, cat, frog, wild goose, and various birds - and from ten nature sounds - wind, water splashing, rain, thunder - which are electronically processed. The piece was commissioned by the Budapest Film Factory "MAFILM" and was realized in the studio of the Filmfabrik "Exaustud" in 1973.

Recording of César Franchisena's "Tres momentos magicos" ("Three Magical Moments"). This is the second of the three movements, which were conceived as contrasting autonomous pieces. It is a non-directional piece that revolves around a limited number of motifs.

Recording of Oscar Bazán's Austera.

Recording of Karel Goeyvaerts's Parier sur huit chevaux n°1.

Recording of Claude Colon's Diastasis. Diastasis means separation. Separation between an instrumental play and a set of sounds obtained with a generator. Dialogue. Osmosis. Separation.

Recording of John Cousins's Christmas musik.

Recording of Bohdan Mazurek's Epizodes.

Recording of Branimir Sakač's Synthana, made in collaboration with Paul Pignon. Sakač describes this piece as an attempt to coerce the machine to "yield his feeling of the moment," which results in a desire for simplicity, for extended durations which bring security.

Recording of Wilhelm Zobl's Andere die Welt, sie braucht es.

Recording of Liviu Dandara's Fresca. Fresca synthesizes folk sound phenomena that accompany the daily events of Romanians. There are three intensity curves, proportionally equal. They correspond to the songs/signals of work, funeral music, and love songs. The dynamic culmination is reached in the same section, which interferes with the space and time of the folk festival. The final represents the filtering of a reverberation of the culmination of the work, accompanied by fragments of the motive-echo, which suggests permanence.

Recording of Otto Laske's Structures IV: Distances and Proximities.
