The great Giddins, critical gatekeeper of 20th-century showbusiness, assembles a collection of pieces from the late 80s and early 90s. As one of America's foremost authorities on jazz, the best entries are on practitioners of that music, wherein Giddins demonstrates his molecular historical and technical understanding of the genre. He throws in a few filmmakers and a handful of writers (prompting one of his best lines: "the gripes of Roth") to affirm his cultural well-roundedness, but his musical ear is clearly his primary muse.
