If you haven't seen it, this article [1] on the London Review of Books about Glenn Gould is a good start. It's a really long essay on why Glenn Gould is amazing while Alfred Brendel doesn't get it, only for Brendel to show up in the "comments". These comments are actually letters to the editor, so it's the world's most educated and polite internet fight.
And if you can tolerate the meme format, [2] is my favorite academic fight of all times.
