progressive rock in crisis

There will be a few modern prog rock bands coming along. Youthful exuberance. Some of these will be pretty good, age is not necessarily a prerequisite for skill. 
They'll release some music: no one will put their hands in their pockets for it. It's like global warming, everyone knows it's happening, but it's someone elses' problem. 
The bands, after one or two albums, get totally disheartened and (to Mosh's chagrin) give up.  Prog rock albums usually take one or two iterations for ideas to get good and develop. So the best bits never happen.

Musicians, as I think I mentioned, then get the idea that involving the general public is just a headache and then either give up or play amongst themselves for their own entertainment. I can definitely see this happening more and more often. 

The result is that, yes, the music industry is in crisis and hence specialised music is in crisis. It's a sad state of affairs, and most likely inescapable, as a result of technological and societal change. 

One aside. Bands are now asking for kickstarters to release albums. In a lot of cases, the kickstarter fee is way above what the price it actually costs to record, mix and master an album. I've done complete albums for free for musicians, I do know the costs. What's happening is that bands, tired of being ripped off, are, in fact, returning the favour to the general public - "no fee, no play". The same token applies to concert tickets. If bands haven't made any money by record sales, ticket prices go up for concerts (mainly to line the pockets of promoters, who haven't had any money, either) or you get inflated festival tickets. This is the only way of getting money out of the "fans" and not one I subscribe to, either. 

But that's the way it seems to be going.... "supply and demand". 

Music sales have been plummiting all across the board for years now.

In fact i recently read that Mozart as well as older music outsold new artists for the first time a couple years ago.

As many new artists as we add here will tell you that prog isn't in a crisis of being created.

The crisis is in musicians making a living. It also seems music is less important to the youth than it was in previous generations with all the newer distractions like video games and virtual reality just to name a couple things.
