The Aeolus Quartet’s mission is to share a vast and eternally powerful string-quartet repertoire with wide-ranging audiences. Based in New York City, the award-winning ensemble places new and lesser-known works side by side with the time-honored masterworks of the medium. The quartet performs at a bold range of venues around the city, in addition to its extensive touring, and this free performance in Madison Square Park is an enticing chance to enjoy their artistry in a casual outdoor setting.
