I will take the diametrically opposite view and say that most, if not all of them, would be either irrelevant or marginalized. There would be exceptions, of course, but most would be trapped inside their time windows as "clues to the new direction" and would quickly find themselves superseded by younger artists...who, in like manner, would become footnotes in musical history as time progressed. Or not.
That is exactly right, which is why 'true success' is not down the amount of contracts you get to sign, the boatloads of product you can shift, the amount of adulation you can garner, but simply the amount of fulfilment you can get out of the job you do.
None of that transcribes on to any headstone, so no point worrying that the big break is just around the next corner, it ain't, it's right here, right now where the best memories will come from further down the line.
As Ian Hunter once liked to say
"You ain't the nazz, you're just a buzz, some kind of temporary" So to paraphrase our 'ol pal, rock on, droogies, rock on...
I can't help missing some of 'em though, which was the second part of Maurice's question.
