Commercialism is indirectly proportional to musical innovation. Also the older one gets, the easier it is to see the derivations.

It is a huge and complicated subject to grasp how and why the world of Art changes but it is heavily connected to technology. In the world of painting for example the discovery/invention of new dyes and paints is what made possible each new sea change genre, simply because without those new colors those genres wouldn't have been even possible. Couple that with one of the fundamentals of interest and entertainment, surprise (read "new") and it's pretty easy to see that as amazing as Rembrandt was and still is. when all artists have to work with is dark earth tones at the time, it could get to be boring same ol' same ol' and far more difficult for new artists to get exposure and funding to refine their "chops"

In Music, electronics changed everything, starting with recording, making it possible to make money 24/7 and not just by live performance any longer. This provided vastly increased motivation and inspiration to seduce artistic minds into the field of Music. When amplification was invented not only did live performances suddenly reach a much grander, and even more influential scale, but the instruments themselves were transformed and expanded. I'm sure you can imagine that without amplification there would be no Rock of any era. Anything even remotely like it would have had far less emotionally exciting impact.

The Digital Age and file sharing undid what recording made possible and the business of Music became far less lucrative for Artists and combined with the fact that daily music was performed mostly in bars and nightclubs which has been hugely impacted by views on alcohol and increased (and rightful) intolerance for drunk drivers, there's no longer a plethora of lower level performance venues to hone skills, see what works, and survive while doing it. Additionally, and much like the above noted situation with Rembrandt's limited window of time heavily affected by technology, I once read a fascinating comment written way back in the mid 70s that "Rock musicians have a difficult job because it's all pretty much been done before, and even worse for guitar players since it's all been done by Jimi Hendrix already". Young kids today cannot possibly grasp what Music was like when Jimi came along and BB King before him and just how huge a change they created, just how revolutionary they really were since after them everyone borrowed heavily from them to the point the beginning is now blurred.

So much of today's Music is in a very weird place, where there is a complete lack of any avenue for musicians to survive and grow only slightly offset by the same sharing that killed recording. On top of that once the Music Business burgeoned from recording, radio, movies and television and became a global market of many billions of dollars it not only attracted musicians but businessmen. Those businessmen now actually believe they don't need artists, that they can put together faces and personality roles that look attractive on screens, give them dance and singing lessons and autotune any defects and still have content to sell. It works. They can... But it gets really stale, really fast.

Now The Digital Age is just gathering momentum in not just the recording and distribution of Music but also in the creation and another sea change is underway. Like you, having grown up with Rock 'n Roll and blazing guitars, and in my case also having spent much of my life in the Music Business, it is really hard for me to transition into the newest stuff and I despise the Corporate Rock that Bill Hicks warned about that is actually here now, but I do see a change coming.

Try this on for size as an example and see if you can warm up to what is coming. It's damned good IMHO and does offer Hope for a better Tomorrow.

Are you sure your issue is with the music and not with the engineering? In the 2000s, there was a "loudness war" where recording engineers would would master music recordings as if they were commercials, with the entire song at the same level of volume and almost no dynamic range.

I am discovering Michelle Blades, after listening to « Le Cours de L'Histoire » (“The course of history", both meanings), on France Culture.

The intermissions in Scientific broadcasts are these days filled with very fine music, oftentimes relatively modern compositions and musicians that I do not know.

Sometimes I do know them, though, like in « Les Chemins de la Philosophie » (« The Paths of Philosophy »), where I liked very much “Chekeeta” with Chet Baker, although the trumpet stays much in the background. I cannot find that one on YouTube.

But anyway, if you want musical voices, listen to just any woman philosopher like Cynthia Fleury or Gwenaëlle Aubry. I do not know why, most of the time, I even understand their discourse; but if not, it is still a pleasure to listen...

Still more like this:
Asa - Murder in the USA (France Inter: « Sur les épaules de Darwin, Les dangers de la séduction », today 11h03)

A discussion of the situation in Burkina Faso gave opprtunity to listen to Victor Démé. I had lost the reference but just searched for “Burkinabe Blues”. Victor Démé - Djon Maja

... not in loudness at least.
And this has become the new normal by now, to the point that you just cannot play 60s/70s music side-by-side with more modern music, if it hasn't been remastered.
I don't think this would influence my listening tastes, but it might be harder to actually get to know music that hasn't been (re)mastered in this way.

A sure sign that you're getting old!
I have been experiencing the same; not to the point of hunting the stuff down, though.
The first example you linked is very nice indeed!

I am listening to C.W. Stoneking - Jungle Blues over and over.
Recommendation straight from here!

Good God, they're way better now that they've dropped the female vocals.

Bob Dylan - Tell Me That It Isn't true.

I have picked randomly on the guitar and found a nice place for a Hm7 chord, where I had not yet suspected one. The songs from *that* record are mastered by applying the same four chords all the time... most of the time... let's say. I may have overlooked something.

My all-time favourite metal band, and going over their '80s catalogue never gets old.
