Maria Elena Gonzalez has an exhibit planned at the Museum of Arts
and Design, a piano roll with perforations in the form of birch bark
patterns, Skowhegan Birch #1.  Randolph Herr will be playing the roll.

She would also like to include a Conlon Nancarrow piano roll.  Does
anyone have one that she can use?  Randolph has not been able to find
one.  Contact Maria at megemege@aol.com.geentroep [delete ".geentroep"

Here is the info and a link where you can see a video of the curator
speaking about the "Against the Grain" exhibit and a clip of Skowhegan
Birch #1:
