I have a solid rec. This book, organized around 43 songs, is a brilliant, moving exploration of the creative genius that emerged from the alchemy that was John & Paul's relationship. I read a chapter a day, then listened to the focal song, often hearing it anew. It was a tremendous ride.

It is such a treat to work with this crazy talented group of colleagues from Columbia and Toyota Research Institute to build a useful app to leverage the findings from our research on optimal ratios of peace speech to conflict speech in the media. This is good tech.
