Holly discovered her unique and recognizable voice at an early age, learning to sign along with recordings of some of the world’s great singers. After graduating high school, Holly attended UCLA but her academic journey ended after just a few months when she was spotted by agents and drawn into the world of film and television. She did guest spots on TV shows like The Partridge Family, Room 222, All in the Family, and played supporting roles in films like John Cassavetes’ Minnie and Moskowitz and George Roy Hill’s Slaughterhouse-Five. She moved to New York and performed for a short run in Hair on Broadway but soon turned to singing full time, as a soloist as well as sharing the stage with her sisters Laurel and Timothy. Throughout her career she has enjoyed collaborations with such artists as Mercedes Sosa, Ronnie Gilbert, Inti Illimani, Emma’s Revolution, and her long-time songwriting partner, the late Jeff Langley.
