But even that gets tricky, as she is not the performer for any of the recordings.
It's a strange world though, when so many people focus on centuries-old music by dead German men, that's going to be harder to market. My first glance at Apple Classical a few weeks ago suggests that it's trying to cater to that crowd.
Bandcamp is better for living composers (and preforming musicians) than a lot of other traditional options. For example, if you have a successful performance is a piece, Parma Records will reach out to you and offer to do a "professional" recording. They'll ask for $20,000 and you'll get a box of CDs (not sure if they do that last part anymore but I would not be surprised). A surprising amount of musicians go this route, because they don't know any better.
Anyway, point is, Bandcamp is awesome.
I think I see what you mean in relation to what audiences Apple is presumably trying to cater to, though I have no market knowledge as to how “classical“ music audiences truly segment. Apple Classical becomes similar to Apple Music a way to (re-) discover both old catalog and new releases. Listening to Toscanini this morning, the performance and music sounds as fresh in 2022 as it always did.
