I missed this little diatribe from Bernard Holland in the Times. Thanks to Carmen Tellez for bringing it to my attention:
Unpleasant truths were another topic brought back forcefully by a concert at the Kitchen in September, by the fine young group Either/Or. Here was a program of 1960s arrogance and self-absorption, with people like Cornelius Cardew, Christian Wolff and Earle Brown as the main offenders. Listening to a collection of composers sharing inside jokes and private messages in music that reeked of contempt for the public made me get down on my knees and give thanks that an era so damaging to music was over. It didn’t drive an intelligent public away from classical music by itself, but it helped.
