Les Fleurs de Mal (The Flowers of Evil), from Oxford University Press, and re-released as one of the Oxford World's Classics. (I've linked you to Amazon, but locals can probably find a fine copy at Babbitt's!) He read from this sexy edition, but you'll see another cover below.
Jim organized the reading by decade, starting with a few poems from the 1960s, and incorporating some translations along with his own work (including a collaborative translation from a German poet! Why didn't I write stuff down? Enthralled, I guess.) He had a perfect balance of humor and seriousness. For example, he revealed that the only poem he's written since 2010 is a limerick...and he'd spare us that. (Of course, now I want to hear it.)
And he left us, somehow, gazing at a universe of stars and listening to the breathing of whales.
I'm delighted to report that Jim used the two-poem warning--in fact, a three-poem warning--something I recently read about at Voice Alpha, a site devoted to advice and support on reading poetry aloud. He began, "I have two more poems from...and then one more poem," and made the audience laugh with "only three more poems to go," but we were perfectly content!
