Popular Music, Gender, and Postmodernism: Anger Is an Energy begins by tracing the migration of cynical academic ideas about postmodernism into music journalism. The result has been a widespread fatalism over the presumed ability of the music industry to absorb any expression of defiance in hip hop and rock. Commercial "incorporation" supposedly makes a charade of musical outrage, somehow disconnecting anger in music from any meaning or significance.

Author Neil Nehring documents the considerable damage done by the Journalistic employment of this tenet of postmodern theory, particularly in the case of the late Kurt Cobain of Nirvana, whose emotional intensity was repeatedly belittled for its purported incoherence.

As a rebuttal to academic postmodernism and its exploitation by the mass media, Popular Music, Gender, and Postmodernism emphasizes that emotion and reason are mutually interdependent. Though mistakes can occur in the conscious choice of an object at which to direct one's feelings, the preverbal appraisal of social situations that generates emotions is always perfectly rational.

Nehring surveys work in literary criticism, psychology, and especially feminist philosophy that argues on this basis for the political significance of anger even prior to its full articulation. The emotional performance in popular music, he concludes, cannot be discounted on the grounds, for example, that lyrics such as Cobain's are difficult to understand.

After detailing more and less progressive approaches to emotion in music criticism, Nehring focuses on recent punk rock by women, including the Riot Grrrls.
