You can watch any of the Berlin Philharmonic concerts that were streamed “live” for many seasons during a 7 day period for free.  The variety of programs is staggering as well as the long list of conductors including some back to von Karajan and Abbado.  If you’re interested act quickly!

 

This 7-day free period will not last forever! Here is the URL:

You will have to sign up in some fashion, WSNC cannot attest to the ease of use.
