Here a continuation of my absolutely incomplete choice of historical sound works, and also some miscellaneous issues.
FREEDOM TO SOUND*
Steve Reich: It's Gonna Rain, 1965
Fluxus Anthology, Zona Archives, 1989
John Cage performing Water Walk in a TV show, 1960
Charlemagne Palestine's ecstatic Strumming Music in 1974: Bösendorfer's resonance at its best!
The same artist more than 40 eccentric years later
Menno Aden: Panel Flat, 2014 (excerpt)
Laurie Anderson: Song for Juanita, first performed in 1977. A language piece for tape-bow violin, voice and piano
A nice compilation of the threatening chord rhythms in the first part of Stravinsky's Le Sacre.
And again and again the wonderful freedom to music of the genius Jacques Offenbach!
For those who like browsing through more sound samples by artists including biographies, glossaries etc.,
I recommend once more:
Or this huge source of sound art, anyway:
GRAYSON PERRY IN SEARCH OF THE DEAD OF THE AVANT-GARDE, ON BBC:
Alain Resnais: Toute la mémoire du monde, 1956
Téo Hernandez: Pas de Ciel, 1987
* after the title "Freiheit zum Klange", a radio series and a film by Guy Schraenen.
