Small niche labels will never lose their customers for sure..
I'm gonna go with "think again"!
Not a single business / person / entity can count on an absolute devoted following that is faithful day in day out. It just doesn't work that way, for very many reasons that are also out of your control as well.
Niche markets work really well with specialty products, exclusivity, luxury, etc. where you actually control the supply to generate demand and excite sense of ownership. Meanwhile certainly that can to an extent work with music, and that's why we're seeing a small but steady resurgence in interest for vinyls, and the packaging & product offer is right along those lines you mentioned (artistic statement, work of art in and of itself, etc.) I don't think that it's actually a long term sustainable avenue, more like a band-aid to stop the bleeding if you will.
+ whatever niche market you happen to fall into will have 'x' amount of pockets with 'y' amount of people trying to get into them. More often than not the x value will more or less stay the same or dwindle while y is ever increasing. you make the maths...
And yes, you can educate and generate awareness so people care about the art, but you will have a very hard time making them want a product that well, how can i put this, they do not want!
Music is in this fairly unique position where the physical support is no longer necessary to its distribution. So it's only a question of time before it actually becomes completely obsolete (or close to it anyway) Convenience and ease of access to the actual product (the music itself) is definitely overshadowing the desire to acquire a physical support for it, which is now perceived as a burden and an annoyance instead of the actual work of art in and of itself.
to be continued (I have work to do around the house...)
