"Peters presents a work on improvisation that is itself an improvisational work—what he calls in chapter 4 a 'live enactment of aesthetic judgment.' As not only a philosopher but an experienced musician with a wealth of knowledge of the subject, he clearly understands his topic both viscerally and philosophically. He provides more of an exploration than a philosophical foundation for improvisation. With lively descriptive and critical examples of jazz improvisers such as Lol Coxhill, Bernard Purdie, Charlie Parker, and his own band, Stinky Winkles, Peters displays an extensive background in Continental philosophy, music history, and education. Hegel, Nietzsche, Heidegger, Deleuze, and others are liberally referenced for theoretical connections. The reader should be warned that this book sometimes has a seat-of-the-pants feel that can be refreshing and stimulating at times but can seem scattered and arbitrary at other times, depending on the reader’s taste and mood. Undeniably, the diligent will learn much about the history and theory of musical improvisation, and a lot of philosophy as well. This well-intentioned, often idiosyncratic and obscure book is an enlightening labor of love about a vexing but fascinating topic. Highly recommended."
