The Brits: Elgar, Vaughan Williams, Britten
The Americans: Copland, Gershwin, and ..........
The finest living composer of symphonic music. Someone who gets no respect from the critics because of the chosen medium that he composes for......John Williams.
Think about all of the dozens and dozens of symphonic melodies, marches, anthems, fanfares, etc, composed by John that are instantly recognizable by everyone the world over. Remember, during the golden era of opera, that was the "theater" (show tunes). Beethoven, Haydn, Handel, Rossini, etc were all just as rich and famous. Haydn wrote mostly for parties and the entertainment pleasure of Royalty, etc. Rossini's operas were performed at Casinos, for one simple reason ($$$$$$$). What John is doing is no different. But like many great artists, he will have to be dead for 50 years before anyone takes notice.
I saw a recording at Borders of a cello concerto and other cello works by John Williams, performed by Yo-Yo Ma. The concerto was composed for Mr. Ma I believe. I think I will give it a listen
