"Voice From The Loudspeaker" (Serbo-Croatian: Glas iz zvučnika) is a historic 1975 conceptual sound art piece by the Serbian avant-garde composer and multimedia artist Vladan Radovanović. The piece functions as a profound self-referential paradox, where a recorded voice systematically deconstructs its own artificiality, the physical limits of the magnetic recording tape, and the acoustic reality of the loudspeaker itself.

Performed by Rob HASKINS / Louis GOLDSTEIN
Composed in 1989. Premiered in New York, May 4, 1990.
This is one of Cage’s few “number” pieces that does not utilize time-brackets. Being inspired by a remark of Sofia Gubaidulina, i.e. There is an inner clock, Cage created a composition consisting of 36 lines of music, each containing 5 measures. Within each line, 31 events occur: 5+7+5+7+7, as in Japanese Renga poetry. The pianists play a measure in their own tempo, but the next measure may only be played when both have completed the previous.
In Two2 (1989), written for the pianists Edmund Niemann and Nurit Tilles performing together as the piano duo Double Edge, Cage unites these two themes—a new kind of harmony and renga—in a marvelous way. One finds all manner of sonorities in this work: various triads and seventh chords, triads with other added notes, dissonances with two, three, or more notes, even single tones. More interesting, however, is the fact that so many chords—even identical successions of chords—recur in the piece. The manner of their overall succession, of course, is determined by chance procedures and performance, which guarantee a nebulous ordering that offers a modicum of coherence without any predictability whatsoever.[11] And so the logic of recurrence in Two2 resembles the way that our different friends and acquaintances pass in and out of our lives—a continuity that doesn’t make conventional sense but is meaningful nevertheless.

![Morton FELDMAN: The King of Denmark
Realized by Max Neuhaus.
This recording should be played at very low volume - so that you almost dont hear it.
In many ways, The King of Denmark is an anti-percussion piece. It is to be played very softly using only the hand and fingers - no sticks or mallets. Its notation on a graph indicates how many sounds are to be played per beat and whether they are to be in high, medium, or low registers. Even though a tempo runs throughout, no rhythmic coherence emerges. Sounds simply float out, detached and weightless. One instrument has no more sonic gravity than another does. A small bell weighs the same - takes up the same acoustical space - as a large gong. An auditory illusion follows: close your eyes and you can imagine that the instruments are being played at their natural volumes. They are sounds in many different loudnesses, but they are being heard from different distances. The gong is really forte but it is heard from the distance of fifty yards. It sounds as soft as the little bell six inches from your ear. Mirages of distance appear and evaporate again into music. It is like rain or the sound of rain.
These illusions come from Feldmans love of the pulsating but rhythmically directionless canvases of Mark Rothko and other American Abstract Expressionists. Directionlessness is key here. The King of Denmark is music that refuses to dictate the way it should be perceived. It does not light a particular way nor lead you by the ear like an angry headmaster along a corridor of preferred comprehension. It simply floats in timeless ether to be looked at from any angle, any proximity, any point of view. Samuel Beckett, writing much later, in 1975, with no particular thought towards Feldman, comes closest to the heart of the King of Denmark:
only dust and not a sound only what was it it said come and gone was that it something like that come and gone come and gone no one come and gone in no time gone in no time. [from That Time (1975)] Morton FELDMAN: The King of Denmark](https://i.ytimg.com/vi/MQmDrHs9oXo/mqdefault.jpg)
