Something I do love about classical recordings is how differently some conductors and orchestras might interpret a specific piece. An example: The third movement of Debussy's Nocturnes (titled "Sirènes") is most often performed with a women's chorus. My favorite recording of this piece was performed with children's choir instead. The difference in vocal quality is marked. The children's pure vocal tone feels far more eerie and siren-esque than the harsher vibrato and warble of a female chorus. Ironically, I have no idea who conducted/recorded this version of the piece.

Do you have a link so I can listen to it?

I recommend this to everyone will listen: Christian Tetzlaff’s most recent recording of the Bach Sonatas and Partitas for unaccompanied violin. It was from around 2017 or so. Just superb in every way. His interpretations have a real improvisatory character that fits with what we know about Bach’s own performance practice. They are recorded on a modern instrument but his articulations sound like Baroque equipment.

Covers or re-recordings in pop music often sound completely different from the original too, of course...

Do get into classical music. As others have noted, yes interpretations can vary, but don’t worry about that initially. It’s relatively subtle. All you need to keep track of ultimately, initially, is the name of the piece and the composer.

If you want to send me an email I'd love to give you some starter suggestions for becoming a listener.

Decent starting place: Osmo Vanska. Recently retired conductor of the Minnesota Symphony, they recorded all of the Beethoven symphonies and most of Mahler’s, they’re excellent and easily found on streaming platforms.

Some good contemporary soloists: Alexandre Tharaud, Stephen Hough, Peter Hill, Jenny Lin, Isabelle Faust.

Thanks!

If you want to go down the rabbit whole a little further, the classical music writer/blogger Charles Downey has been doing annual “best of” lists of classical recordings since 2004. I like these lists in particular because for the most part they’re new recordings and help me find active performers who tour that I might want to see live. https://ionarts.blogspot.com/search/label/Best%20of%20the%20...

This is a fantastic recommendation.

I'm pretty sure I discovered Carlos Kleiber through Building a Library. Listening to his Beethoven Symphonies was like almost listening to different music, especially when comparing against say Karajan...
