The first movement of Beethoven's Violin and Piano Sonata No.5, Op. 24, dubbed the Spring Sonata, played by Gidon Kremer and Martha Argerich. I was fortunate enough to attend a concert by Kremer in the 1980's. I don't think I really understood what great musicianship was, as opposed to virtuosity, until that concert. For Kremer, every note is part of a bigger whole. In this video, it is not clear that Kremer and Argerich are on the same page though.
Below is the whole thing with Anne Sophie Mutter and Lambert Orkis, which has better balance.
