At the end of 2011, Joanne Hubbard Cossa retired from a forty-year career in arts administration. At that time, she was President and CEO of the American Music Center. During her seven-year tenure, she commissioned Taking Note: A Study of Composers and New Music Activity in the United States; AMC hosted the annual meeting of the International Association of Music Information Centers; the organization's endowment increased by more than five million dollars; Counterstream Radio was founded; and she instigated and shepherded (to coincide with her retirement) the merger of the American Music Center with Meet the Composer to form New Music USA.
From 1988 to 2003, she was Managing Director and later Executive Vice President of Symphony Space, a multi-disciplinary performing arts organization in Manhattan. To its renowned literature and music marathon programs, she added repertory film, dance and children's fare, and oversaw the renovation and transformation of the old movie theater into a two-auditorium arts center.
She worked for the Chamber Music Society of Lincoln Center from 1973 to 1988, beginning as its Music Librarian (and page-turner), advancing to Development Director, and becoming Executive Director at the end of 1981. In her Chamber Music Society years, CMS released numerous recordings, toured nationally and internationally, commissioned some forty works and quadrupled its endowment.
Between Symphony Space and AMC, she was the General Director of Glimmerglass Opera for the 2003 and 2004 summer seasons. In 1971, after working very briefly as an actress and singer, she began her career in arts administration by mailing subscription tickets for New York City Opera and New York City Ballet. She sings with the New Amsterdam Singers and tours with the group internationally. In retirement, in addition to serving on the Board of Trustees of the Kurt Weill Foundation for Music, she is writing a long-postponed historical novel and a family history; she also enjoys yoga, gardening, and travel.
