In Interstitial Soundings, Cynthia R. Nielsen brings music and philosophy into a fruitful and mutually illuminating dialogue. Topics discussed include the following: music's dynamic ontology, performers and improvisers as co-composers, the communal character of music, jazz as hybrid and socially constructed, the sociopolitical import of bebop, Afro-modernism and its strategic deployments, jazz and racialized practices, continuities between Michel Foucault's discussion of self-making and creating one's musical voice, Alasdair MacIntyre on practice, and how one might harmonize MacIntyre's notion of virtue development with Foucauldian resistance strategies. The nature and boundaries of music are continuously being reshaped by musicians and audiences alike.

Through careful and incisive readings, she harmonizes aesthetic and race theory with Foucauldian genealogy and MacIntyrean virtue ethics to produce an excellent synthetic work that will be of interest to readers across multiple disciplines. --Michael Barnes Norton, Assistant Professor, Department of Philosophy and Interdisciplinary Studies, University of Arkansas at Little Rock In her exciting and important text, Nielsen employs jazz theory to make multiple, complex schools of thought simultaneously accessible and challenging. . . .
