Did you read the actual original post at the start if this thread?How often are you getting out to blues jams, blues shows, blues fests, or gigging blues music yourself? There are a lot of commenters in these threads sounding off on things that I would guess they have little to no participation in. Kind of like your "seems like blues societies" remarks.... When was the last time you participated? Depends on the society, depends on the jam. I'm not so sure it's easy to have your ear to the street from Maine, no offense. What works for country in Nashville, with it's huge musical market share and Nashville's large tourism draw for country music won't correlate to blues as the OP suggested.
Blues is working man's music and was last in the billboard pop charts as routine 80 years ago so "preserving"it as you suggest is just making Joe Q Public foot the bill for yet another failure-to-be cultural project. Swells and well to do old hippies will foot the bill for classical, which is ingrained into the education system, and tribute shows which are now everywhere and quite successful thanks to sentimental grey hairs. Blues has long been a much more limited market share. It isn't the music of people making big money and it has few cultural icons to sell it. It's the music from people on the bottom. The couple record companies who put on blues have pitifully small budgets for producing and marketing the albums.
Some sound alike doing Howling Wolf for ten bucks located on some "dirty street in chicago"? You're not going to have foot traffic if people fear for their lives. Beale street in Memphis, also not exactly a pinnacle of safety, has kept the ball rolling to some smaller degree without it being a taxpayer funded grift for the operators and few juiced in musicians that will get gainful employment from grant funding. Blues, it's either organic, or DOA.
I tend to agree with what @schmee said:
It was almost entirely about historic sites falling into ruin in Chicago, while pointing out that in Nashville there is more preservation of the old time venues where that history was made long ago.
Thats what Im talking about, possible ways to preserve historic Blues joints, in a situation where they cant make enough money to keep them maintained in presentable condition, and no philanthropists are interested in saving them.
As for preserving the playing of Blues?
I played Blues in my first year or so learning guitar, as a framework for understanding the variety of musics built on that foundation.
Since 1982 or so I have not played Blues, gone to Blues jams or Blues shows, bought Blues albums newer than ABB at the Filmore which is barely Blues but the closest thing Ive bought thats that recent.
More modern or more recent music I consume is not Blues, I just dont really care for shred Blues or acid rock blues etc etc.
Im glad when at least somebody keeps playing older music styles, but I dont want to devise tricks to get kids today to recreate old time music.
However, I do see great historic value as being lost if nobody bothers to designate at least some of the old (Chicago) Blues clubs historic, and finds a way to save them in some form.
Blues is a hugely important piece of US history.
If the Chicago Blues history is being lost in terms of a few places that were central to that history?
Such an easy problem to solve.
Elon Musk or Jeff Bezos cant force kids today to play the Blues but they could endow a few historic buildings as easily as ordering a cup of coffee.
