For those of you not already acquainted with it, we'd like to direct your attention to what is almost certainly the Web's most beautiful and beautifully conceived, designed, and organized classical music website: the Berlin Philharmoniker's Digital Concert Hall. It's a largely pay-to-view operation that presents the Berlin Philharmoniker in live concert in high definition video and audio, and, considering what's on offer, ticket prices are cheap, cheap, cheap (about $15 USD per concert). Monthly passes and season subscriptions are available as well, also cheap, cheap, cheap. Registration is for free. Our U.S. symphony orchestras should all take their cue from this website, and put up websites of their own of the same type and quality. In our estimation, no single marketing tactic can equal it in promoting both the orchestra and classical music. Do click over and take a look/listen.
Update (7:45 PM Eastern on 25 Nov): If you balked at our use of the phrase, Berlin Philharmoniker, read this before firing off an eMail of objection.
