Music Education Hall (one of 4 components of the Green Music Center) opened its doors in 2008 to students taking classes in the two 60-person classrooms. The focal point of the Green Music Center is a 1,400-seat concert hall featuring precision engineered acoustics, named the Joan and Sanford I. Weill Hall.[27] The entire rear wall of the hall opens to lawn seating for a total of 4,000 additional guests.[2][28] The Hospitality Center, which includes a restaurant/executive conference center, opened in 2010. A $12 million donation from Joan and Sandy Weill, announced in March 2011, provided the funds to complete the concert hall for the fall 2012 opening.
