A good review would be longer than the book itself. This isn't a good one. It's scattered. My thoughts all run together.
I really admire Pinsky and always like to read what he has to say about poetry. I've heard him speak a couple of times and he was wonderful. He's done more for American poetry than anyone I can think of. That said, I often have a hard time reading his poems. You can't be lazy. He requires a lot. Sometimes, I find myself thinking: He knows too much.
I always feel that I'm missing half the poem because I just don't get the references, the allusions -- and allusion is a big theme -- at least in Gulf Music. There are different Gulfs to consider: the Persian Gulf, the Gulf of Mexico (even Golf at one point), but most of all, the myriad gulfs in our lives — between thought and language, between who we are and who we might become, or are becoming. There's so much here about how language works, how important it is to civic/civil discourse, and of course, to our survival as individuals, as a nation.
Regarding missing references and allusions, I found this (in Pinsky's note at the end of the book) somewhat comforting: "The references and proper names in these poems do not intend that a reader rush to Google or an encyclopedia. "Sibby Sisti" and "numerus clausus" have meanings, but such phrases appear also for their quality of forgotten-ness, a quality that lives in varying, unstable relation to meaning." Whew. I get easily annoyed at writers who think readers should Google what they don't know. What happens at a reading? Hmmm? (I really enjoyed Pinsky's Note.)
This isn't an easy book. I didn't like all of the poems, or not all of the equally. And the ones I liked best are probably the more accessible ones. I particularly liked "Poem With Lines in Any Order," which tells a story, or several stories, really, but interleaved here are the lines: "You can't live in the past," "Nobody can live in the future," and "There's no way to just live in the present." He's always got me thinking about the gulf between then and now, now and what comes after. The theme runs through the entire collection. As does the idea of the thing, thingness, the nature of things. As do memory and forgetting.
I also liked "The Dig," and "In Defense of Allusion," and "If the Dead Come Back." And this little gem, the poem in its entirety:
XYZ
The cross the fork the zigzag — a few straight lines
For pain, quandary and evasion, the last of signs.
