Interesting stuff & it's something that has been mentioned a few times on this board.
There is many aspects that come into play, 90% of the reggae that i used to listen to came from JA .
That was many years ago, that little island had the best musicians, producers, singers, the whole spiritual force of the music was there, even the herb was good !
Times change & people move on, the internet helped to change a lot of that, no more secrets now everything is out in the open.
Back then there probably was a lot of good sounds from elsewhere, it's just that the radio stations never played it .
Some kids don't want to play the music of their fathers. So many factors do come into play, back in Marley's time, ghetto kids could look up & aspire to play in a band & tour the world & spread the message of Rastafari, not many people interested in those teachings now.
Sure i would never count JA out of things in the future, because no one knows what the next generation will bring.
The thing is though, it's a world thing now, I don't really need JA for my daily dose of fresh reggae, i get it elsewhere.
I don't really miss the old days, it's better to be in the present & prepare for the future.
At present listening to a good group from Italy. Back in the day that would not be possible !
