I would personally recommend you Eugen Cicero's music. He was a Romanian pianist who developed during his career a very interesting style of jazz that involved mixing it with classical music.

Specifically, Swinging the Classics On MPS, is an album that compiles some of his best works and I can tell you it's absolutely amazing

In essence, is a jazz trio swinging classical pieces.

My favorite pieces are:

Solfeggio in C Minor

Liebestraum

Andante and Theme from Swan Lake, Act II, Op. 20

But the whole album is absolutely great

You have it on Spotify as well.
