Let's remember that for every horrible, sudden, shocking thing that happens in the music world, somewhere else, off in another corner somewhere, something wonderful might be happening.
Like these recently discovered metal masters of songs like this one, from Duke, and "Ain't Misbehavin'" from Louis. Even the guitar solo on this cut (at 2:10 or so) is pristine, and those things were hard to record back then.
That's life, isn't it? Learning to take the bitters with the sweet, as Muddy Waters said.
Life is loss, and it doesn't help matters to take it too hard.
