Nice read, I had never heard of Chet Baker before. I wonder if his style* is at all responsible for the current trend of the depressed-sounding pop singer. Billie Eilish comes to mind, but there are plenty of them. It's like someone dragged them out of bed into the studio against their will, so their passive-aggressive response is to record the lowest-effort vocal performance possible.
* "His singing was softer still, often lingering just above a whisper."
