Shirley Walker, an immensely talented composer best known for her work in the Diniverse died Wednesday of a brain aneurysm at the age of 61. She composed the themes for The New Adventures of Batman & Robin, Superman: The Animated Series, Batman: Gotham Knights, and Batman: Mask of the Phantasm among many other works. Her finest work was Mask of the Phantasm, imho, and its haunting theme is something I listen to regularly. Her final credit will be on the upcoming Direct to DVD release of New Frontier. IMDB listing RIP, Mrs. Walker.
