The sociological theory of practices developed in this book from the concept of the event compels us to question how practices not only chain into forms of practice. The approach also allows us to see how these practices give rise to practice formations that manifest as enduring zones of intensity within society. This very problem is at the center of the considerations pursued here and is unfolded through an analysis of pop music as a formation of practice. As an exemplary case study, the author chooses the Love and Peace Festival on Fehmarn from the year 1970. In doing so, the book brings to life a period of pop music that has much more to do with our present than it may seem at first glance.
