[a fool in paradise]

Several game changers for music:

The Beatles/Capital/Ed Sullivan 1964 coordinated media attack.
The Beatles “concept album”.
Woodstock.
Keyboard and drum synthizers in the 1980s.

Music has never recovered.

Mass consumerism and pushing “product” (an identity as much as the music) rather than selling songs.

[Revolting cat!]

I think it was during the 25th anniversary of Sgt Pepper that I read for the first time a critic who dared to say that “this chit doesn’t hold up!” He was right of course. Concept albums don’t hold up, rock operas don’t hold up, the first Little Richard album on Specialty does hold up.
