It's not not surprising that Rufus Wainwright would become a musician and singer. He is the son of singer-songwriters Loudon Wainwright III and Kate McGarrigle (of the McGarrigle sisters). He has just released his second album, Poses.
A special in-studio concert and interview with Kate and Anna McGarrigle; Loudon, Rufus, and Martha Wainwright, and other. They all sing and play on the new album, "The McGarrigle Hour" (Hannibal).
