Celebrating 66 years of performances this season, The Little Orchestra Society shares the vitality of live classical music and seeks to build future audiences by presenting innovative concerts that incorporate multiple art forms to foster a deeper understanding and enjoyment of music. Musicians who perform with The Little Orchestra are covered by a Local 802 union contract and earn union benefits and wages. On these pages, photographer Walter Karling caught up with the musicians at a recent rehearsal at the DiMenna Center for Classical Music on West 37th Street.
