I've liked the Berlin Philharmonic's digital concert hall for a few years now, but it is expensive and I let my subscription lapse. For Christmas we re-upped for a month so I could get a feel for what's been happening in my absence. When I went to sign into the new sub, my old account info was still present on the computer - and I had a free week waiting for me. Apparently everyone gets a free week right now if they've ever been registered. Not sure what this means for brand-new subscribers. If you haven't tried it, I think it's a very nice service. Well-shot video, well-recorded audio and a fairly deep archive. I'm watching Emmanuelle Haim conduct and perform Handel's Resurrezione from Halloween of 2014 just now.
