Who says people knew how to programme concerts back in the old days?
On Friday 9 March 1973, the Halle Orchestra had come down to give the London premiere of Ligeti’s Melodien, a major new work by a composer had worked up a strong UK reputation by that time. Most people interested in new music would come to that, right? Get some decent reviews, some props for the orchestra, all of that.
Except that Stockhausen was conducting the London Sinfonietta that night in a concert of his own music, including premieres of Stop and Ylem, in the Queen Elizabeth Hall. Yup, the building right next door. Ooops.
