OK...the dude on the left with the insane hair. Who has hair like that unless you're some flake dying for attention? That's why i believe there are trolls and mean comments on social media. To put some balance in the world of narcissists.
You seem very fixated on the age of his audience. Is that why you're contrasting him with Mayer, your supposed chum (#humblebrag)? He may pull in a younger crowd, but plays commercial dreck that is forgettable about 10 mins after the song ends, imo. As said earlier, he is much more renowned for his horndog skills than his guitar skills, although he is a good player. I'm a ways under 60 and I've gone to one of JB's shows. Lots of other youngers folks there as well and I didn't see a single walker in the venue. I guess I'll be one of the only fans left when the core fanbase is "dead", as you so kindly prophesized. Oh well, enjoy "Paper Doll" or "Who You Love (feat. Katy Perry)" of any of the other stone-cold Mayer classics that definitely don't cater specifically to a post-millennial teenage female audience.It kind of does matter. I understand what you're saying and Massa and I are about the same age.
He's making money and his career is doing well. I'm just saying it will be interesting to see where he is 10-20 years from now when the core of his fanbase is dead or not able to go to shows anymore.
If you go to a (for example) Elton John or John Fogerty show you'll see fans of all ages. From what I've seen the average JB fan is probably at retirement age or older. Imagine if Taylor Swift was only pulling in people 65+, you wouldn't find that odd?
He seems to be a smart guy. I'll be interested to see what direction he goes in 10-20 years from now (providing he doesn't die from his brain freezing).
How old are his band members? Maybe I'm wrong and he plays with a bunch of guys his own age. Imagine Clapton if The Yardbirds were all like 60 when he was 20.
