Some big orchestras such as the NY Philharmonic and the Berlin Philharmonic are adapting to new, instant access technologies for obtaining music, such as iTUnes and Amazon Mp3 download sites.
However, these sites and other digital technologies are still relatively young. Also, since they are designed for popular music "songs", they are not easily archived or tagged for classical music, which needs detailed information on composer, soloists, orchestra, multi-movement works.
Still, the trends are unstoppable, and other orchestras must adapt or fail to compete.
I am happy to say that the Columbus Symphony's CEO and President, Rolland Valliere, has already initiated use of these cutting edge technologies for our orchestra. We have our own channel on InstantEncore.com, where you can listen to every concert we perform for free. And if you are a subscriber to the Columbus Symphony, you'll have download access to concerts on your series. Pretty nice, huh?
