Jeff Newberry posted a list of 13 poets as a proposed answer to this: Say someone asked me, "I kind of like poetry, but I don't know anything about contemporary poetry. Who should I read?"
I spontaneously came up with this list of 14 (which I have put in alphabetical order), throwing in some German and French poets:
Stallings, A. E.
Young, C. Dale
Levine is the only one on Jeff's list and mine.
Tomorrow, of course, I would come up with a somewhat different list.
