Yeah.....Miles Davis was another.....Genius or not....He ran out of tunes.....I have wondered that too, and looking at what has happened to some of the people from that era who survived, I feel it's a bit of a coin toss as to what might have happened with Jimi.
He was at the peak of his game when he passed away, cementing his legendary status. But what if he'd gone on to release additional music, and fell into one of those places where he couldn't quite figure out how to compete with the changing landscape as disco and New Wave took over in the late 70's and 80's. I'm thinking about what happened to, say, Jefferson Airplane, or several other iconic names from the 60's and early 70's.
It's possible he might have gone on to put out a few more records that ended up in the cutout bins (remember those?) and then disappeared into relative obscurity. Maybe today he'd be playing small clubs and Vegas in a comeback attempt.
But who really knows? The man was talented AF but the buying public doesn't always continue to reward that.
I suspect that Jimi would have had trouble maintaining his status unless he'd managed to take his music beyond what he already blazed a trail with.....
What that would have been?.....Anyone's guess but it sure might have been fun finding out...
