Over the past 80 years, the Coolidge has hosted most of the 20th-century's greatest performers and composers, including Copland and Stravinsky. Today, the theater draws musicians from all genres, including classical, jazz, and gospel, and the hall continues to wow audiences with its near-perfect acoustics and sightlines. Concert tickets are free, but must be ordered in advance through Ticketmaster. Because of the Library's security procedures, patrons are urged to arrive
30 minutes before the start of each event.
