Thank you so much for that video clip of Martha Argerich playing the Beethoven Piano Concerto No 2. My wife and I sat here, having our mid morning cup of coffee, whilst listening to it and thoroughly enjoying it.
I have a friend who runs a classical music low power FM station in our home town. I phoned him, and he knew the video - turns out he has the DVD. He listened to the sound coming from my laptop over the phone. I will now send him the link to this very well patronised thread.
