Eusebius said:Rock was a product of an era which is now gone. Just like jazz and classical music. All these genres live on with their aficionados, but the days when they were the beating heart of a culture are gone.
Then again, the music industry has changed a great deal & is always changing.
Bands may have complained ten years ago that the internet was ruining record sales.
Yet the era of selling ten+ million copies of one album was only really a thing of the 80's & 90's.
Selling ten million copies of one record offhand wasn't really a thing in the 50's & 60's.
Or filling stadiums the size of sports fields, was a big thing of the 80's & 90's. Not so much prior or since.
