American Pop Rock Band. Formed by Emily and Siouxsie Medley, when Emily was 16 and Siouxsie 15, the name evolved from "Epiphany" to "Dead Sara" in mid-2005. The name comes from the Fleetwood Mac song, "Sara." There's a part in the song where Steve Nicks sings, "said Sara," or "that's Sara." But Siouxsie Medley and Emily Armstrong always thought that she was saying "dead Sara" instead.
