Stimmt, Yoko Ono ist in der Hinsicht ja geradezu legendär :-))
Die Portsmouth Sinfonia, die auch dabei ist, hatte ja ein ziemlich originelles Konzept. Brian Eno (Produzent einer ihrer Platten) hat das so zusammengefasst:
The philosophy of the orchestra was that anybody could join. There was no basis of skill required for joining. The only condition was that if you joined you should attend rehearsals and take it seriously. It wasn't intended as a joke - though it was sometimes extremely funny. The orchestra only played the popular classics, and it played only the most popular parts of these popular classics, the bits that everyone knows.So was ging wohl nur in den Siebzigern :-)
Viele Grüße,
