Len responded to me: >The "riot" at the premiere of La Sacre had more to do with the >choreography than the music. I did not know this. I was using the reference to illustrate the idea that music of this kind can be difficult, particularly for those bred on classical music that is less violent in tonality (and rhythym of course.) (It is not difficult for me; I find it very accessible and often moving. But I recall one classical music enthusiast's response to my declaration of intention to go see La Sacre in concert as simply "why?" I gather there are many who share this attitude.) It is popular to call whatever occurred a riot. I thought I had read that it was really a rather violent argument that erupted between different groups of people as they were leaving the performance, and that it was about the music. Has anyone more detailed information about this? (I prepare to go search google after I send this.) Michael
