Weill Lawn and Commons provide outdoor performance venues at Green Music Center, a world-class performing arts complex. The landscape architects prepared overall master planning and landscape architectural design.  A simple, dramatic grading plan unifies project elements, directs circulation, and buffers concert venues from adjacent roadway traffic. Weill Lawn is the first acoustically protected outdoor venue on the West Coast for symphony orchestra and other highly polished musical performances. The lawn complements architect William Rawn’s design for the 1,600-seat Joan and Sanford I. Weill Concert Hall, which opened in September 2012 and is generally considered one of the world’s most acoustically superb concert venues. When the pavilion’s back wall is opened, Weill Lawn expands its interior capacity with a series of lawn terraces that accommodate up to 5,000 visitors in chairs or 1,600 seated at tables. Weill Commons provides a larger, informal amphitheater for 10,000 along with an open-air pavilion for major gatherings.
