Wynne currently works out of Seattle, Washington. She attended Douglass College, and Rutgers University for her undergraduate studies and later received an MFA from the Milton Avery Graduate School for the Arts, Bard College in 2004.
Wynne is best known for her work under the name Tracy + the Plastics. While working as the Plastics, Wynne played the role of three characters: Tracy and her back-up singers Nikki Romanos and Cola. In live performances, Nikki and Cola (aka "the Plastics") existed in pre-recorded video which played behind Tracy as she gave live vocals. The project ended in June 2006.
In 2005, Wynne and fellow artist K8 Hardy collaborated on the New Report, a video piece in which the two played reporters on a fictional feminist news station. The film combines activism and campy satire, critiquing the absurdity of televised news. It was part of the Tate Modern Level 2: Media Burn exhibition.
Her installation entitled "Peas" was featured as a Susanne Vielmetter Berlin Project from February to April 2007.
In 2008, Wynne received a Genius Award from Seattle's The Stranger (newspaper), which included a check for $5,000 and a notification via cake. The cake was received while Wynne was teaching art to kids convicted of crimes at Southeast Youth and Family Services in Columbia City. She responded to the honor by saying, "You have no idea what this means. . . . Now I can make art again.”
