The speaker is totally plugged into the New York City arts and cultural scene. He also follows the latest global trends, such as experimental French theater and the up-and-coming African literary movements. It's ironic that he would name all of these examples of "high culture" in a poem about a so-called "popular" art form – jazz. The poem seems to make the case that Holiday's work belongs right up there with the big players of world culture.
The speaker is a slave to the fads and trends of high culture.
