A musical imagining of the future and an exposition of a challenge to the normative historical discourse are the subjects of Erik Steinskog’s chapter on Afrofuturism. These topics are dealt with through a discussion of “blackness” and a theoretical discourse that addresses the musical style and polemical and political stance of afrofuturist musicians such as Sun Ra and others following in his path. Steinskog suggests that afrofuturist music is a form of sonic time travel that intertwines the modalities of time represented by notions of past, present, and future, his argument being that reimaginations, reinterpretations, and revisions of a normative past are represented in the technology and music of the black future.
