In this excerpt from "Homeland: The Story of the Lark," the documentary on the making of Laurie Anderson's Homeland included with the album, Anderson discusses the challenges involved in gathering the thousands of files she had assembled for the project over the years, the daunting task of creating a single album from them, and the unfailing support she received from her husband and Homeland co-producer Lou Reed throughout the process. Reed offers his perspective here as well, as does album engineer Mario McNulty. The documentary is by filmmaker Braden King.
