After watching The Making of Sgt Pepper, I've listened to the album a few times, from beginning to end. They said it's a concept album, but it isn't really. There are four songs that are in keeping with the Sgt Pepper theme, but the rest are Beatles songs. A few that could have been from the pre-Pepper Beatles. But the album made another statement that did mark a turning point: We're going to try new ideas. We're really going to do it, not just talk about it. We're going to use the remarkable place we're in to innovate. Further, this isn't about fame or wealth, it's about creativity, human expression. For the rest of their careers, as a group and individuals, they continued to try new ideas. And they inspired a generation of us to believe in our own ingenuity as much as any tech hero did, more I think (though I wasn't inspired by them, I was of them). The beauty of Pepper is the lives of the people who created it and their ability to influence. #
