The San Francisco-based Women’s Philharmonic, which had promoted the role of women in the classical music industry for nearly a quarter-century, officially closed its doors on Sunday, nearly three years after having to suspend its regular concerts due to a lack of funding. Some of the WP’s programs will be folded into the American Symphony Orchestra League, and much of the work in which the organization had been involved will continue in other forums, but the demise of such an important organization is still sad to see, says Joshua Kosman.
