Rhiannon is a vibrant, gifted singer, composer, and master teacher who has been bringing her potent blend of world music, jazz, improvisation, and storytelling to audiences for over three decades. Her journey took her from a South Dakota farm to New York, where she studied theater and earned her MFA from Cornell University. For the next ten years, she worked as a singer, actor, and director in New York, Chicago, and San Francisco. Her richly expansive and experimental vocal style is greatly influenced by her early life on the South Dakota prairie, the vibrant musical cultures of these cities, as well as that of coastal northern California, her current home of many years.
In 1976 Rhiannon cofounded the groundbreaking all-woman jazz quintet Alive! This pioneering group toured internationally and released three albums during their ten years together. She is also a founding member of the innovative a cappella ensembles Voicestra and SoVoSo.
In addition to her ongoing solo performing and recording career and her current ensemble project, Bowl Full of Sound, Rhiannon enjoys a longtime musical collaboration with vocal improvisation master Bobby McFerrin. From 1986 to 1992 she was a member of his 12-voice orchestra, Voicestra. In 1993-94, Bobby formed the improvisational quartet Hard Choral, featuring Rhiannon. In 1997 she recorded "Circlesongs" with Bobby, and she has been a featured soloist on his U.S. and European Voicestra tours since 1997.
