One sentence for me, stands as an epigram for this fascinating, provocative, enlightening collection of essays, reminiscences, and riffs:"What was great about the fifties is that for one brief moment — maybe say, six weeks — nobody understood art. That's why it all happened. Because for a short while these people were left alone. Six weeks is all it takes to get started."I'm not fond of the star-ratingsystem here, but ... five stars!
