An army brat, Jo Williamson spent her childhood moving all over the United States and Europe living on different military bases with her family. She fell in love with performance at the age of five when she played Narrator Number One in her kindergarten class production of Peter Rabbit. At the age of 18 she moved to New York to formally study theater and music. It was here she started playing guitar and writing songs.
In 2005, Jo Williamson formed a short-lived fusion (jazz, classical, folk) group with trumpet player Charlie Porter called Joellen and the Dogbiters. She has also worked with avant-garde/classical composer Faye Ellen Silverman who wrote a fifteen-minute piece called Left Behind for French horn and voice based on a musical story Jo created with Ann Ellsworth called Left Right. As an actress Jo has performed in some of Shakespeare's plays most recently playing one of her heroine's Joan la Pucelle in Henry the Sixth-Blood and Roses. Jo has also worked on sound scape projects with video artist Chris Allen and the Light Surgeons and other artists. Currently she dabbles in radio co-hosting with Bob Johnson on his Second Saturday Magazine up at WPKN in Bridgeport, CT. Jo performs her music solo in and around the tri-state area.
