The article is largely framed from a mainstream perspective. I suspect the stuff I’m interested in, e.g. independent artists selling very bespoke product from Bandcamp, Rough Trade etc, high-end audiophile jazz reissues etc will be safe for a very long time yet, as will the endless expensive dad-rock reissue box-sets. These markets are established now. FWIW I’m actually astonished how much vinyl Taylor Swift managed to sell, but to my eyes she is off at one extreme of the market rather than the area that has become pretty solid of late. New pressing plants are coming online, there are companies making brand new pressing machines again. Independents are buying them, e.g. Jack White’s Third Man Records.
The high price of vinyl is now largely normalised. It is arguably not much more in real terms than it was in the ‘50s, ‘60s and ‘70s, but it represents a much needed re-balancing to the crippling exploitation of corporate streaming. There is no way in hell minority interest independent music can survive on a Spotify type model.
