Not that I had any doubt that David Greenspan, stalwart performer/writer/creator wouldn’t handle the material as expertly as he did. Still, understanding, interpreting then speaking as well as acting text by Gertrude Stein is not an easy task. Greenspan’s spin at it Composition…Master-Pieces…Identity (running until 6/27 down at The Connelly Theater (220 East 4th Street, Manhattan) was pretty much masterful-as I say I expected it to be-but I also understood what he was on about, no easy task when it comes to Stein’s ruminations on these three subjects.
