Recording of Chris Chafe's "In a World" for cello and computer sound. Computer sounds were realized at Stanford University's Center of Computer Research in Music and Acoustics. Software was created to control legato phrasing of singing voice models, and to perturb them in direction of other instrumental sounds,

Recording of Reed Holmes's Carousel for choir and tape. The two movements represent a different aspect in the cycle of life: movement 1 "The Whispering Wind" is from the point of view of the Elder, introspective and thoughtful, and movement 2 "Carousel" is from the point of view of the Younger, rhythmic, aggressive, spontaneous, and freely melodic. The choir adds heterophonic elaborations of the pattern to the second movement.

Recording of Juan Marcos Blanco's Huellas.

Recording of Roberto Doati, Gianantonio Patella, and Daniele Torresan's "La materia è sorda" performed by Lorenzo Rizzato (speaker) and electronically realized by Granziano Tisato.

Recordings of Gerhard Stäbler's Twilights "protokolle für tonband gleichzeitiz gespielt mit window" (Ewilights "Protocols for tape played simultaneously with window"). Poems were written by Ernestro Cardenal and other texts were taken out of "NEWSWEEK" issues between Auguest 1 and 8, 1983. Produced at the Computer Center of Stanford University/California.

Recording of Paul Dolden's "The melting voice through mazes running." The piece was composed by using computer and concrete sounds.

Recording of Kristi Allik's "What if...". The title refers to the composer's most common thought during the creation of the composition; the work was the result of constant questioning and exploration, mainly in the area of timbral synthesis and sound juxtaposition.

Recording of Douglas Doherty's Impact. The sounds and structure of the work evolve through powerful and complex impact resonances.

Recording of Peter Martincek's Les insectes. Incorporates the sounds of insects into a electronic piece of music.

Recording of John Cousins's "Edit for Pauline" for tape.

Recording of Shin'ichi Morita's Coeficient of rebound. The piece focuses on the concept of rebound, which makes up the natural rhythm and influences the sound. Based on a calculation Morita made on the computer, he added realized sound and natural sounds to the rhythm of rebound to create the piece.

The kendang is a Javanese drum. In Javanese music, the drum sounds are onomatopoetic, that is they are duplications of spoken language. An appropriate kendang player, however, will always tend to enrich his sound repertoire by imitating arbitrary sounds of the environment. My composition Dialogue refers to this. First the computer-generated sounds are introduced in an onomatopoetic way and imitated by the kendang player. Then the computer sounds develop in a way as to move finally far beyond the expressive power of the kendang. The natural and the synthetic sounds enter in a heavy conflict leading to a climax. The contrast is, however, bridged eventually by fragments of the Javanese music "Subakastawa" in the tender Slendro-9 tuning. The piece was created at Utrecht Muziekcentrum on the 24th of January 1984 with the collaboration of the Javanese kendang player Supangah Rahayu (Paris).

Sequence Symbols exemplifies the composer's exploration of the concept of modulation spectra considered as inharmonic "harmonizations" or chords. The gradual transformation of basic note groups related by common tones provides the underlying pitch structure. Each group so derived in turn furnishes the intervals that are treated as generating dyads for the inharmonic chord-spectra. Chord-spectra can be enlarged by the simultaneous sounding of the chord with its transposition at a desired interval. In this way a variety of tension and release patterns are created by associating a specific interval with various kinds of chord spectra. Common frequency components between the chord-spectra provide a basis for hierarchical structuring of the materials generated by each note group and its possible interval transpositions. The general wavelike form of the piece (at times dramatic, ironic or static) corresponds to memoents of prominence by a note group or interval or their transpositions. On another level, the wavelike shape of the piece can be attributed to the interweaving of sections and their interruption of and by each other. The conception of the work varies from symphonic scale to inteimate chamber-music proportions - a formal combination that seems rather well-suited to music conceived in terms of digital sound …

Recording of Lárus Halldór Grímsson's Winter Romantic.

Recording of Stephen Montague's Tigida Pipa. Commissioned by Elms Concerts for Singcircle, with funds provided by the Arts Council of Great Britain. Tigida Pipa was composed in Ghent, Belgium, and completed in London in January, 1983, but revised several times until 1989. The text consists of invented words and percussive sounds whose inherent rhythmic structure propels the work at breakneck speed through a rondo of sonic adventures.

"Comeclose and sleepnow" is based on the homonymous poem by R. Mac Gough, recited by Stephen Montagne. The piece is composed in six sections. In each section are developed parts of the converted text and are highlighted phrases or words of poetry. All the sound material of the piece was composed solely by transforming the recited text.

Within Time Mark (commissioned by percussionist Kathleen Kastner), are specific considerations including a continuum of timbre - thus providing for an integration of electroacoustic and live sounds without the loss of individuality, and spatial disposition - wherein the location from which sounds emanate within the host performance space is also a parameter for composition. Originally realized in 1983 with concrete and modular voltage-controlled synthesis techniques (including much analog tape editing), the electroacoustic portion of the composition was reworked to reduce the inherent analog tape hiss and was then digitally re-recorded in 2000.

Solar Wind is an electronic piece based on synthesized audio representations of bow shock interactions of Saturn and Venus with the solar wind as observed by Voyager, Voyager-2 and the Pioneer-Venus Orbiter. The source tape was generously supplied by the project director of the plasma wave instrument, Fred Scarf, of TRW, for NASA. The plasma wave instrument detects phenomena associated with solar wind interactions in space. The instrument, placed aboard this spacecraft, gathers information and analyzes it using a sixteen-channel spectrum analyzer. The data is transmitted to Earth and drives a computer which controls the amplitude of a sixteen-voice music synthesizer. In some bow shock interactions the actual frequencies of the phenomena are replicated; in others, some frequency shifting was necessary. Time compression is set to a 480:1 ratio. The final sequence of the composition uses the source tape with minimal manipulation. The middle section of the piece (bow shock sequence) uses the source tape, but heavily modified. The remaining segments are loosely based on the source tape.

The title of the work comes from a word Nahuatl which literally means "burning water". Piece quickly explores a sound material frequently associated with maracas, harps, bamboos and a guitar. The live sound of the maracas comes from the traditional rhythmic patterns found in most traditional Latin American music, models that the performer is asked to combine with great dexterity to build wider and very complex rhythmic structures. These rhythmic structures are then confronted with passages of the same complexity on the tape, creating and developing ever more a "star" polyrythm that finally disintegrates. The path is then drawn for a traditional accompaniment game of maracas.

Recording of José Augusto Mannis' Cyclone. The composer describes this work as a language of electroacoustic music in which what counts is the gesture of the sound. The movement of the composition is lively, vigorous and energetic, creating clear musical articulations.

Recording of James Dashow's In Winter Shine. This work was commissioned by the MIT Council on the Arts. This work has been separated into two tracks and is meant to be played "quartet-style" with each loudspeaker in the quadraphonic work thought of as a separate performer. The title of this work comes from a line in John Ashbery's poem "Litany".

Recording of John Michael Clarke's Soundings. This piece is an exploration of the sonic world of the cello hence the title "Soundings". The title relates to "resonances", the tape being a reflection of what the "live" cello is playing. This is because most tape sounds come from recorded cello sounds that were then processed in an electronic music studio. There are also some computer generated sounds in the middle part.

Recording of Iancu Dumitrescu Motto : Opera Aperta. Ursa Mare is a music intimately linked to Orphic-incantatory thought and practice, conceived in the spirit of ancestral, intuitive, initiatory and magical music; its aesthetic, like that of some other works, is subordinated to an acousmatic. Through this technique of composition, which is also a mental technique, which effectively penetrates into the orphic space of a "substantiality of color", by discovering the design of a particular species of sounds, "diagonal sounds", which arise from the selective and elastic combination of certain natural harmonics, organized in "diagonal multisons." It is by the "diagonal," by a sensitive sound thought, that we succeeds in discovering the subtle connection between native (concrete) sound, classical instrumental sound, the sound of special instruments and electronic type sound, at the same time as performing a synth between the archaic (suggested by the echo of traditional Romanian and foreign instruments) and modern, within the same artistic thought.

Recording of Jukka Ruohomaki's Hommage à Winston Smith. This work is a recomposition of old sound materials made for am experimental short film. The film celebrates the year 1984, and it develops further the basic ideas of G. Orwell's novel: human beings are produced, exploited and destroyed according to the needs of society. The sounds have here undergone manifold processes, male voices being the main material.
