A lot of great music is packed into this slender, discount-format CD, one of the best on this label. Rodrigue’s electroacoustic pieces have a fluid style that is refreshingly different from the jarringly erratic nature of most tape-music. Like a roller coaster ride through a spectacle of stereophonic fireworks. Not merely entertaining either: compositionally, the pieces are compelling, and they are no less artful for all their seeming concern with impressive technical tricks. It took some talented hands to shape these little tracks. Rodrigue is my top recommendation to insomniacs who listen with headphones.

Yet another compelling release from [empreintes DIGITALes] in their “affordable” series. Bartley is based in Toronto and has been involved with electroacoustic sounds for over ten years. This CD contains compositions spanning her career and is characterized by spacious, slightly icy, and ethereal works. Two of the pieces use vocal sources to solid, but differing effects. The intensity (without the drama) of the other two pieces is something we could hear more of in a genre that often overemphasizes “dramatic” sounds.

Before reading the [original 1991 edition] accompanying booklet (over 200 pages) I had no idea Dhomont was considered a major figure in electroacoustic music. Though his GRM album has always been one of the most interesting discs on that label. What Dhomont’s music exhibits on these two CDs is a command of sequential events, a syntactic order, that surpasses any such achievement that the LP had. This “order” is something I start to pick up on upon repeated listenings and it’s the hallmark of talent for any self-respecting acousmatic egghead. While much of this seems like amorphously structured ear candy, I entertain hopes of finding brilliance in some of those parts too someday.

There is so much musical output contained on these two discs that it took me several listenings to come to grips with it all. In the liner notes, Dolden describes his current artistic intentions as involving the “speeding up of an excess of musical ideas so that the composition and its materials exhaust themselves in the shortest time possible”. Most of the works here reflect this principle in different ways. Another perceptual factor in listening to these pieces is the manner in which Dolden intersperses pieces for tape alone with works featuring solo performers backed with material from the solo tape compositions. This approach has the twofold effect of emphasizing hitherto unstressed aspects of the tape pieces and also of blurring to some extent the distinctions between the individual works. These considerations aside, Dolden constantly varies his approach, not hewing to a quick-cut, sound-mass approach to the exclusion of linear development.

Dolden first composes simultaneous lines of music on manuscript paper, then digitally records each line as performed by an acoustic instrument. The parts are then digitally mixed with little or no signal processing. His exclusive use of acoustic instruments is justified by his opinion that electronic synthesis techniques are unable to produce a large palette of convincingly different timbres. A huge palette of acoustic sounds are used tor these pieces, including nearly every orchestral instrument, voices, ethnic and folk instruments, and percussion. And although he does not use signal processing, he occasionally achieves DSP-like effects through ingenious mixing of his sound sources. The mixing often involves overlays of 40 or more tracks, and the massed effects and climaxes achieved are impressive. His use of digital editing is equally responsible for the results, as the pace and mood of the pieces are largely controlled this way.

The title cut and the last work in this collection, both for tape alone, could not be more contrasting. L’ivresse de la vitesse (1992-93), encapsulating as it does the composer’s more recent methods, is an exhilarating outburst of contrasting ideas and styles at a rapid-fire pace. Veils (1984-85) is a halfhour, 3 movement composition which explores a sonic world of subtly shifting timbres, comprising drones on acoustic but ambiguous-sounding origin. After the adjustment is made to the leisurely pace of this piece, it is thoroughly satisfying.

With the exception of these two pieces, I gravitated toward the pieces that featured solo instruments because of the focus they provide. This may be because Dolden does not emphasize spatial placement in these wtirks. Often, the sound struck me as completely up-front and two dimensional. No doubt this is partly because he eschews most signal processing,but the overall sound of the acoustic instruments tends to be a little washed-out. Experimenting with different microphones and preamplification should help — quality of engineering is important when this approach is taken, especially when there is extensive mixing and overlaying. The solo instruments help to impart more of a spatial quality. Revenge of the Repressed. Resonance #2 teatures a performance by cellist Peggy Lee which ranges from fleet passagework to elegiac phrases and extended techniques.

The harpsichord part in Physics of Seduction. Invocation #2 takes on a thunderous and threatening aspect in the hands of Vivienne Spiteri, thanks to Dolden’s multitracking and close-miking techniques. Two pieces feature saxophonist/clarinetist Francois Houle. One of these, In a Bed Where the Moon Was Sweating. Resonance #1, strikes a perfect balance between the virtuostic solo clarinet part (often multitracked with amazing etfect) and the tape part with its echoes (or “resonances”) of preceding events.

Physics of Seduction. Invocation #1 features the composer on electric guitar in a technically adept performance which also makes use of the processed timbres which are the domain of the instrument. Dolden shows a flair for these changes of tone. His performance on guitar here gives further evidence of his mastery of the sonic resources at his disposal.

Hal London is a freelance, part-time composer who divides his time equally between acoustic and electroacoustic music. Dolden’s approach in this respect is of special interest to him.

This CD begins and ends with random street interviews on computer generated music. The techniques employed are varied as the answers of the interview participants. Appleton was co-designer of the Synclavier. In the 70’s he toured with this instrument now used by Laurie Anderson, Peter Gabriel, etc. To say Appleton’s music is diverse is an understatement. Many tape pieces are included in his varied collages. This disc is remarkable in the transference of this “electroacoustic” technique to CD. These pieces were created from ’66 to ’96, 30 years of experimentation. Appleton idenitifies two techniques: “abstract manipulation of timbre” and “the use of ‘found’ music and recognizable ‘objets sonores.’” The notes further give Appleton’s remarks on each composition and the time and place of creation.

Varied sounds come in glimpses, interrupted by periods of silence, or near silence. This might sound even unsettling, but it strikes me more as a series of provoking, sonic propositions. Each idea stands out clearly and time granted for consideration. The French and English liner notes describe “unstable spaces” while Roy’s own notes bring into play the aural color, or “klangfarben.” This seems better suited to the title, to me. I see monuments of diverse form and color placed periodically along a road. Further notes explore each of the four tracks (the shortest cut is nearly ten minutes). Avant-garde compositions for the stereo adventurer.
