Recording of Wes Richard Wraggett's The Trials & Redemption of Henry.

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 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 Stephen Perry's Voices from Purgatory. The work is an amalgam of a variety of treatments of the human voice. In particular, extensive use is made of layered montages of material generated by means of the voltage controlled filter. Stephen Perry is also a graduate of Queen's University in Electrical Engineering.

Recording of Denis Smalley's Vortex. "Vortex" centers primarily on the types of sound movements that suggest analogies and swirling images, sound objects, textures, and rapidly moving patches of sound, often around an axis. Such movements can evolve in a variety of directions: we can let them hover or play them. They may have a combined action or follow each other or be swallowed up by events of greater force. The sound events of various attacks, sizes and orchestrations give vocal points to the movement. They signal climates, initiate changes of direction or change of quality by evolving in their movement. Commissioned by Tim Souster with the help of the Art Council of Great Britain.

Recording of Denis Smalley's Vortex. "Vortex" focuses first on the types of sound movements that suggest analogies and vortex images, sound objects, textures, and patches of fast-moving sounds, often around an axis. Such movements can evolve in a variety of directions: they can be let go or played. They may have a combined action or follow each other or be engulfed by events of greater strength. The sound events of various attacks, dimensions and orchestrations give vocal points to the movement. They signal climates, initiate changes of direction or change of quality while evolving in their movement. Order of Tim SOUSTER with the help of the Art Council of Great Britain

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 Hildegard Westerkamp's A Walk through the City performed by Norbert Ruebsaat, speaker. The piece is for two electroacoustic sound tracks. The poetry was written by Norbert Ruebsaat. the piece is an urban environmental composition based on Ruebsaat's poem. It takes the listener into a specific urban location - Vancouver B.C.'s Skid Row area - with its sounds and languages. Traffic, carhorns, breaks, sirens, aircraft, construction, pinball machines, the throb of trains, human voices, and poetry are its "musical instruments." These sounds are used partly as they occur in reality and partly as sound objects altered in the studio. A continuous flux is created between the real and imaginary soundscapes, between recognizable and transformed places, between reality and composition. The poem is spoken by the author and appears throughout the piece, symbolizing the human presence in the urban soundscape. Its voice interacts with, comments on, dramatizes, struggles with the sounds and other voices it encounters in the piece. "A Walk Through the City" was composed at the Sonic Research Studio at Simon Fraser University and, in its final stage, at the CBC studios in Vancouver, with the technical assistance of Gary Heald. Many of the sounds were taken from …

Recording of David Porter's Walking Bells for tape. The piece is a tour through an environmental/concrete landscape. It is another variation on the "cumulative form." This is the second in a series of four tape pieces. As with all these pieces, this piece comments on political and compositional methods and devices. In this instance, the piece makes reference to another composer whose style is borrowed. Other than that, it is pure experience. This piece should be listened to with speakers placed well apart and volume up the the highest comfortable level at the last two minutes of the piece.

This work is performed on the Fairlight CMI with the output first processed by a Lexicon PCM 70 MIDI-controlled digital effects processor then by a Lexicon 224XL digital reverberator. The PCM 70 is in a "resonant chord" program, the 224XL is in a concert hall simulation program. With the exception of the glockenspiel, all of the fairlight sounds were created by extensive vertical layering of complex sampled sounds. These sounds, often as many as ten layers of orchestras, electric guitars, choruses, etc., were the first material for the thinning process of the PCM 70 resonances. The six resonances are all controlled by one MIDI controller which has a different scaling factor (degree of effect) for each one's pitch center. As a result, changes in the overall pitch area of the processor also change pitch relationships of the resonances. The sounds alternate between processed and unprocessed, with the glockenspiel usually acting as a signal of impending change or return to the melodic theme.
