Those words belonged in the original to Treebeard, I think.
With Bach, there's more to it than that. He represented a style going out of fashion, and people were accustomed to hearing that style as old and fusty, and were not disposed to give it a proper hearing. Composition and keyboard students knew differently, but much of Bach's other works were forgotten, and just a fraction were discovered and saved.
I have somewhere an LP that was advertised as The Last Concert of the Modern Jazz Quartet. The first cut opens with a dialogue between the piano and the vibraphone, a dialogue that is a note-for-note quote of the subject of the second contrapunctus of Bach's Art of the Fugue, a massive, abstract, work, Bach's unfinished Last Testament to posterity.
