Lady & Bird are a side project from Israeli-born singer/songwriter Keren Ann and Bardi Johannsson, an Icelandic artist who has worked on film and television music as well as recorded under the name Bang Gang. Highlighted by haunting, childlike voices, Lady & Bird's subdued self-titled effort is a conceptual work about two children living in adult bodies. It was released on Keren Ann's own Yellow Tangerine label in the U.S. in June 2006.
