Last weekend, in Chicago, I picked up NDP#2!
This is an amazing example of the book/multiple/art object/print/collaboration form.
NDP was recommended to me by Rowley Kennerk, and I found one at Quimby's.
The experience of "reading" this edition is so tactile, and includes a variety of audio- cd's and a record, amongst many other stuffs- art and writings.
The whole thing is very Dieter Rot.
