My son (@cmp2020Steemit's Best Classical Music) and I founded the @classical-music account, the #classical-music tag, and Facebook page with this sort of thinking. I don't keep up with it as much as I should, but @bengy has joined our efforts, launched the @classical-radio account, and helped grow the tag into a budding little community.
I would encourage whales and dolphins to also look at the articles we share on the Facebook page. (which are usually not our own. We share them to promote steemit, not ourselves).
