Editor of Genius by A. Scott Berg>>> Max Perkins was the editor of Hemingway, Thomas Wolfe, F Scott Fitzgerald, and other famous 20th century writers. Great, great, book.
Bartending: Cosmopolitan by Toby Cecchini
>>> Very well-written memoir of a bartender in New York in the late 1980s. He invented the Cosmo in NYC while working at the Odeon — on a lark, without thinking much of it. The drink took off, but I think he's still a working bartender in NYC.
Cooking: Kitchen Confidential by Bourdain
Painting: Interviews with Francis Bacon by David Sylvester
Music: Meet me in the Bathroom by Lizzy Goodman
Tech: Chaos Monkeys by AGM
And seconding swyx's recommendations for all things Michael Lewis, who can spin a good yarn about any profession — whether it's baseball managers, junk bond salesmen, or high frequency traders, etc.
I've also picked up lots of good recommendations from this thread https://ask.metafilter.com/243036/Recommend-a-nonfiction-aut... (I, too, like "insidery" type business books. I'm currently reading "The Emperor of Scent" about the world of perfume and it's pretty good! Also looking forward to reading "Ninety Percent of Everything" about the shipping industry.)
