The Real Book (2021)
99percentinvisible.org

Since the mid-1970s, almost every jazz musician has owned a copy of the same book. It has a peach-colored cover, a chunky, 1970s-style logo, and a black plastic binding. It’s delightfully homemade-looking—like it was printed by a bunch of teenagers at a Kinkos. And inside is the sheet music for hundreds of common jazz tunes—also

Getting hit by lightning is good for some tropical trees

The trees may have even evolved to act as lightning rods.
