An Opera Offered on the Installment Plan

NYTimes.com: For opera critics pondering the future of the form, the composer Lisa Bielawa’s latest work, “Vireo: The Spiritual Biography of a Witch’s Accuser,” offers a new twist. The work is a serial opera – serial in the television sense, not in the 12-tone sense – and although it will be filmed before live audiences, it is meant to be seen on television or online, in short installments that will be released over two years. The production will also include online extras, including video clips that look at the process of composing and staging the piece.
