Perhaps it's just me, but I didn't get this link to work. I did, however, boogie on over to the penn sound site to listen to mucho Zukofsky... & it was magical.
worked for me--was accessable--but was a commentary between 3 discussing it. was interesting / enjoyable.
Here's the link for the readings:http://writing.upenn.edu/pennsound/x/Zukofsky.php
