Bill Fontana's Landscape Soundings / Klanglandschaften was a radio project in two ways: 1) radio (microwave) was the means of connecting the live signals from the microphones in the Danube marshes to the temporary studio in the Kunsthistorisches Museum and 2) the sounds from the marshes were experienced throughout Austria as a radio sculpture broadcast by the ORF (Austrian Broadcasting Corp.).
In the original concept, Bill Fontana planned only to create two 45 minute live mixes for the weekly KunstRadio programme (Thursday night at 22:45) during the event and produce short live mixes on the same days for other programs on Österreich 1, (the ORF cultural programme). However it was soon discovered by the producers of the early morning programme that the live stereo feed, from the Kunsthistorisches Museum to the radio studios of the ORF, was available 24 hours a day and the producers of other programmes soon followed.
So for two weeks the real-time sounds of frogs, birds, water, thunder-storms and, sometimes, hikers became integrated into every kind of broadcast - weather reports, talk shows, pop and cultural programs, etc. By the end of the fortnight, the sounds had become so popular that the radio director decided to have the last five minutes of the sculpture transmitted live on all three channels of the ORF - which meant all the radio channels in Austria because, at that time, the ORF still had a radio monopoly.

The two live 45 minute mixes for the Kunstradio broadcasts (Thursday May 17th and Thursday May 24th 1990) presented the artist and the listeners with the problem inherent in the flow of time in nature which is quite different from broadcasting time. At 22:30, the time of the broadcasts, nature - with the exception of frogs and a few night birds - was asleep. In addition, the live mix, for second broadcast (May 24) was partly drowned in the white noise of a torrential rain, obliterating all other night sounds.
