Generational Gaps in Music?

Karen and I went to see a performance by the Tacaks String Quartet yesterday of 3 Beethoven string quartets - all lovely, beautifully performed - at the Hertz Hall on the UC Berkeley campus.

I was struck by the audience demographic, which tended to 99% over 50, just judging by appearance. This isn't the first time I've noticed this when attending classical music concerts in the Bay Area, but it bothers me that at one of the pre-eminent universities in the (world), in an area known for intellectual curiosity, that more young people did not and do not avail themselves of the opportunity to hear world class music played by world class musicians.

Yes, ticket prices are likely high, though I know there is student pricing for these things when they are on campus, as this was, and it was a(nother) beautiful fall day outside, but it gets me wondering whether there is a real generational (not to mention ethnic as there were no minorities except Asian to be seen either) gap in the music world today and whether we're losing the ability to cross generations and ethnic groups and have something to say that is relevant when it comes to the performing arts.

My guess is that the majority of this audience would be unlikely to attend anything with a more contemporary nature to it, whether classical or other musical genres, but I could be generalizing - it's just a hunch.
