Based on my experience with young people who bother to listen to music at all, young boys and men these days generally listen to rap/hiphop stuff and they’re primarily interested in whether the songs have a good beat or a thumping bass.
Admittedly these are generalizations, but I don’t think the generalization is unfair. Many in this thread have noted how there are a lot of great songs being written by Americana artists. How many young people today are listening to that stuff, much less blues or jazz?
About that thumping bass thing, I’ve been a bass head from the time I heard Larry Graham of Sly and The family Stone and the acoustic intonations of Ray Brown on an upright bass. I don’t think the above statements are necessarily true about kids, or should I say young women and young men theses days.
For example this first link is from MonoNeon with Ghost-Note "Live at the Jamm Jam in Los Angeles" and if you notice, it’s packed with general admission standing room only young folks. Or what we would call back in the day a "jam Session". Kinda similar to what their grandparents did many years ago when going to a concert.
In fact I think young people all over the world listen to jazz and blues. This is Ghost Note featuring MonoNeon in Germany, tearing up the stage. Ghost-Note - Featuring MonoNeon live at the Jazz Club Unterfahrt in germany
And the idea that these same young folks don’t listen to blues is totally false as well. NAMM 2016: Eric Gales & Mono Neon Live At The Dunlop Booth
As you see here in this post, young folks not only listen to jazz and blues, but more importantly they play live jazz and blues quite well, if I don’t say so myself. Here’s one for the road. Check out MonoNeon on acoustic bass. MonoNeon with Ghost-Note: "Phat Bacc" | Sugarshack Sessions
