I'm not the writer, so I hope you don't mind my intruding, but for what it's worth, from toft_froggy's "String Theory" linked above is this passage: In 1878, Brahms wrote a piece for the violinist Joseph Joachim, a huge, furious, passionate work so difficult that it was called a concerto against the violin rather than for it. Brahms was a pianist, like Tchaikovsky and Beethoven, and the complexity of his writing was too much for most players[.] And since the soundtrack given here uses Brahms for the second piece, I'm guessing Brahms? (I have one or two works by Brahms in my collection, but I'm the "it sounds pretty" type of musical illiterate, unfortunately.)
