 Linda Thompson's folk roots go back to the 1960s, and of course she was part of the famed duo with her husband at that time, Richard and Linda Thompson, in the 1970s. And a rare vocal condition has kept her from singing, but she continues to write and has a new album of her songs called Proxy Music, which are performed by lots of friends and family, including the Wainwright family. Both Martha and Rufus Wainwright appear on Proxy Music.
