This is pretty good, and funny, and in general the writer knows what he is talking about, EXCEPT - on Bruckner (clunky? F. OFF - I'd love to be that clunky, sucker! Bruckner is BETTER THAN WAGNER - and if you don't understand that you are a moron) and English composers, who more than made up for their previous relative quiet in the 20th century. Vaughn Williams is not great? Then nobody is, bud. And no mention of my main man, Holst? Shit! As in... he is full of.
However he is right about Tchaikovsky and Mahler - they OWN being miserable. And Debussy was a real jerk who wrote great music. Though he underrates Ravel severely - he is obviously one of the "Debussy is far better than Ravel" snobs.
He overrates Mozart. He is not the greatest composer who ever lived by a long shot. Bach is the greatest, obviously, Beethoven obliterates everyone else, and next best are Mahler and then probably Schubert who was less consistent than Mozart but a thousand times more inspired. Also, Da Vinci blew Mozart's ass off the map as a universal genius, though not as a composer obviously. Just take a look at what da Vinci did, in detail, and you will realize there are few humans who ever approached him in range of interest combined with accomplishment.
What else? I forgot but could go on, if I had this guy in front of me. Though it might end up in injuries or worse.
