When the society was founded in 1987 the internet as we now know it did not exist and the only way to listen to the music and consult scores was to visit the society (my flat) where free overnight accommodation was provided. This activity gradually became superfluous as more and more works were uploaded into Youtube. At the time of this update, almost every work can be heard on that site. This is a two-edged sword because no-one knows whether the hits have been off-putting for life or instant or gradual ‘conversion’. The number of hits over sometimes years are often disappointing and the right hand side of the screen simply puts Stockhausen among a list of other contemporary composers of which he is just another name. I will be doing my best to construct talks on other works using the same approach as on the Gruppen talk and the short one on Mikrophonie 1.
