A taste of a great book review by Paul Beston:
Gioia is so confident that newcomers can appreciate jazz in part because he believes that objective benchmarks of evaluation exist, and that, in the case of jazz, we can listen for fundamental “building blocks” such as rhythm, dynamics, pitch and timbre, and phrasing. This view puts him at odds with more theoretical critics who claim that subjectivity is the only aesthetic standard. Nonsense, says Gioia: “Understanding jazz (or any other form of artistic expression) can never be reduced to personal whim or some flamboyant deconstructive manipulation of signifiers but always builds on a humble realization that these works impose their reality on us. . . . and in this manner can be distinguished from escapism or shallow entertainment, which instead aims to adapt to the audience, to give the public exactly what it wants. We can tell that we are encountering a real work of art by the degree to which it resists our subjectivity.” In this one passage, Gioia manages to push back against both highbrow and lowbrow wrongheadedness.
