I hope you're right but the zeitgeist of that period (political unrest, embryonic liberal values, etc) will never be repeated.
The guts behind the music will never be repeated, but there will always be life in good music, real musicians can create a passion for those that listen, music that lasts & you can still listen to that's 20/30 years old or longer will always be listened to by every generation. The stuff now is just throw away in the most part.
The death of musicians like Bowie will inspire people to listen to create their own music. Unfortunately over the coming years I feel we will lose many classic musicians & singers, hopefully in their wake will rise a new generation of angst ridden bands who want to put their point across to everyone & give their own political statements in songs that will stand the test of time.
imo of course.
I had the right letters just not in the correct order.
