Jay Pritzker Pavilion, Chicago

Jay Pritzker Pavilion, also known as Pritzker Pavilion or Pritzker Music Pavilion, is a bandshell in Millennium Park in the Loop community area of Chicago. The pavilion was named after Jay Pritzker, whose family is known for owning Hyatt Hotels. The building was designed by architect Frank Gehry, who accepted the design commission in April 1999. Pritzker Pavilion serves as the centerpiece for Millennium Park and is the new home of the Grant Park Symphony Orchestra and Chorus plus the Grant Park Music Festival, the nation's only remaining free outdoor classical music series. It also hosts a wide range of music series and annual performing arts events. Performers ranging from mainstream rock bands to classical musicians and opera singers have appeared at the pavilion, which even hosts physical fitness activities such as yoga.
