One guiding principle at “Writers at Work” is that good writing is worth savoring wherever one may find it. My guests have included novelists, journalists, playwrights and screenwriters. And I’ve extending invitations to poets and lyricists. All to discuss the joys, heartaches, challenges and satisfaction of the creative writing process. This episode is dedicated to what I consider a model of effective autobiographical storytelling, “Vulnicura,” an album by Björk.
