The Problem of the Future World is a compelling reassessment of the later writings of the iconic African American activist and intellectual W. E. B. Du Bois. As Eric Porter points out, despite the outpouring of scholarship devoted to Du Bois, the broad range of writing he produced during the 1940s and early 1950s has not been thoroughly examined in its historical context, nor has sufficient attention been paid to the theoretical interventions he made during those years. Porter locates Du Bois’s later work in relation to what he calls “the first postracial moment.” He suggests that Du Bois’s midcentury writings are so distinctive and so relevant for contemporary scholarship because they were attuned to the shape-shifting character of modern racism, and in particular to the ways that discredited racial taxonomies remained embedded and in force in existing political-economic arrangements at both the local and global levels. Porter moves the conversation about Du Bois and race forward by building on existing work about the theorist, systematically examining his later writings, and looking at them from new perspectives, partly by drawing on recent scholarship on race, neoliberalism, and empire. The Problem of the Future World shows how Du Bois’s later writings help to address race and racism as protean, global phenomena in the present.

Sound Changes responds to a need in improvisation studies for more work that addresses the diversity of global improvisatory practices and argues that by beginning to understand the particular, material experiences of sonic realities that are different from our own, we can address the host of other factors that are imparted or sublimated in performance. These factors range from the intimate affect associated with a particular performer’s capacity to generate a distinctive “voicing,” or the addition of an unexpected sonic intervention only possible with one particular configuration of players in a specific space and time. Through a series of case studies drawn from Africa, Asia, the Americas, and Oceania, Sound Changes offers readers an introduction to a range of musical expressions across the globe in which improvisation plays a key role and the book demonstrates that improvisation is a vital site for the production of emergent social relationships and meanings. As it does this work, Sound Changes situates the increasingly transcultural dimensions of improvised music in relation to emergent networks and technologies, changing patterns of migration and immigration, shifts in the political economy of music, and other social, cultural, and economic factors.

Improvisation studies is a recently developed, but growing, interdisciplinary field of study. The discipline—which has only truly come into focus in the early part of the twenty-first century—has been building a lexicon of key terms and developing assumptions about core practices. Yet, the full breadth of improvisatory practices has remained a vexed, if not impossibly ambitious, subject of study. This volume offers a step forward in the movement away from critical tendencies that tend to homogenize and reduce practices and vocabularies in the name of the familiar. Chapter authors include John Corbett, Jason Robinson, Kirstie Dorr, Beverley Milton-Edwards, Sally MacArthur, Waldo Garrido, Jemma Decristo, Mike Heffley, Monica Dalidowicz, and Hafez Modirzadeh.
