For sure you are right!
That was the era convergent complicities, everyone was ready to discover not so much consumate a product... The young generations was educated and very distinct from his fathers... We were lucky...
Yes. But they must also be exposed to it! It so happened that in the 60's, 70's record companies saw fit to take on a wide variety of talented and idiosyncratic artists and a good amount of excellent music ended up on the radio. It was there, at the twist of a dial. of course, there was still plenty of music that was not so easily accessible. Luckily I had friends with large record collections who knew much more about music than I did. I was "initiated" into the good stuff. But that was back when many more people had systems and owned records. With no internet, music was a primary form of entertainment.
