Airplanes are great for finishing books. This one was cool AND I learned a lot. A broadly journalistic accounting of John Coltrane's "A Love Supreme," which is arguably his most loved and most influential recording. Lots of info about the years and works leading up to the album, the recording session itself (one night!), and what came next. Lots of interviews with a ton of different people, musicians, producers, label executives, fans and family.
