Self-Portrait in a Convex Mirror - John Ashbery
These certainly are obscure poems, for the most part. Not that the syntax is difficult; but rather the statements, the metaphors and choice of phrases, are so opaquely self-willed. My reaction is mostly to wish for footnotes, then shrug. One exception among those I've read so far is the long title poem. It intrigues me; demands multiple readings and invites them; has some rewards up front but clearly reserves more.
