A few comments about the music. Brahms wrote only one violin concerto and he wrote it for a friend of his. And apparently (obviously?) he composed it to show off the skills of his friend, violinist Joseph Joachim (on the right).
Technically, it is superb. One can hear glimpses of Brahms in the orchestra but the solo part is all technique, especially in the first movement. (Listen to his symphonies if you want to hear the beauty of Brahms.) And yes, violinist Augustin Hadelich is incredible, as he proved again during his encore, flawlessly performing Paganini's Caprice No. 5, a technical and impressive masterly performance. He has his own amazing back story, coming back from a serious burn at age 15 that threatened his future as a violinist (stock photo). But comparing this concerto to Beethoven's Violin Concerto in D (recently read in a review) doesn't work for me, as the latter is stunningly beautiful and the former is just technical to my ears. It's nothing against Hadelich because I'm pretty sure he can play anything, beautifully and perfectly.
The second work of the night was Bartok's Concerto for Orchestra. It was interesting to hear individual instruments/sections highlighted and it was impressive overall but again, we were not swept away. I'm sure this is sacrilege to fans of the composition, but other than parts of the fourth and fifth movements, it all seemed somewhat randomly constructed.
Some music can bring you to tears just through its sheer beauty, but tonight was not that night. It was technically amazing but it did not touch our souls.
