There is a new boxed set of DVDs out now of Barenboim playing and conducting from the piano all five Beethoven concerti in Germany last year. If you can get over the slightly gimmicky aspect of conducting from the piano, the music that he educes from the score is astounding. I've been listening to these concerti for over 25 years and he brings out textures and colors I've never heard in them. I guess this it what happens when a Beethoven expert gets total control over the performance! Plus the video quality is fabulous.
