I am reminded that the Berlin Philharmonic's million dollar technology investment to bring me (and you) their concert series live is up and running!
There are times when I am not looking for the concert hall experience, especially when seats are cramped, the flu is going around, or the tickets you have to get for the best sound are limited ...
(10Euros/$12.50 for each concert or 90Euros/$115 for the season. That's the cost of tunnel and tolls, for a live concert, so... it's attractive.)
