Does Channing Gray have a theory of the degeneration of art ?

Theater review: 'An American in Paris' is a pointless pageant

I appreciate this review of " An American in Paris " by Channing Gray. He saves me money . Thank you, Mr. Gray. Of course THE MOVIES are even worse . Does Channing Gray have a theory of the degeneration of art and decline of culture ? A general " Decline of the West " ( Oswald Spengler ) . Where is inspired MUSIC today - and I am very eclectic ?
