One of my favorites is Tchaikovsky‘s violin Concerto in D. I have a few versions.
Another amazing collection of work to consider is the entire collection of Beethoven’s piano sonatas played by Mari Kodama, hi-Rez and high fidelity recording available by pentatone classics.
Vivaldi’s four seasons is extraordinary popular and for good reason, it’s quite good!
The Bach cello suites by Yo-Yo Ma. He has recorded it three times in his career, the most recent one just came out last year and it is excellent.
Check out anything by Julia Fisher on pentatone.
Also check out some of the Wilson audiophile recordings available at acoustic sounds.
good luck, have fun!
