Query: Two great musicians and the greatest composer

This is sensational music-playing -- and composing. I take away one star because in the faster movements ("toe-tapping Bach") the violin gets buried in the piano accompaniment, played on a Steinway grand (eight-foot?) with the lid fully open. It would have been better for proper balance to have the lid partally open, as it usually is for accompanying, or closed.I suggest starting with the accompanying one-hour documentary, "Bach and me." In it Zimmermann discusses, among other things, some of the more important movements and then plays them, in full.
