I went to the opening last night of the Glass/Wilson exhibition at the Morgan Library and it's fantastic. When one walks into the hazy dark blue soaked room,  the display and lighting are wonderful.  The original Wilson sketches for Einstein and the Beach run on the left wall, while an archival film of the 1975 tour of Einstein in Europe plays on the center wall. On the right wall, the entirety of the Glass manuscript score posted on the wall. 

Photography was prohibited, so I highly recommend a visit to the Morgan which is a great place to go at anytime.
