While trying to avoid turning this into a one-note blog*, I'd like to link to an interesting and much-needed opinion piece. Conductor Kenneth Woods takes aim at a school of writers on music who are currently promulgating the view that modernism in general, and the serial movement in particular, was an artistic dead end because it ignored the preferences of the general listener. Woods makes a persuasive case that attacking these modernist compositions is actually a thinly disguised attack on the very idea of all culture.
Well worth your time.
*The "one note" is probably best summarized as "Yaaaaaayyy, modernism!"
