There are lots of events scheduled this week around the Armory Show and the Art Show. One of the most beautiful spaces on the Lower East Side is joining the fray. Beginning tomorrow and continuing through Sunday the Angel Orensanz Foundation is hosting an open house and free brunch. You’ll be able to look at “Transparent Matter,” an exhibition by artist Angel Orensanz, walk through the galleries and enjoy the spectacular sanctuary in the 1850 synagogue. Angel Orensanz is located at 172 Norfolk St. If you’re interested in attending, you’re asked to RSVP via Facebook.
