Jeanne Barron, Producer

Jeanne Barron’s love for music developed at a very young age. She began playing the acoustic guitar at age 8. Her penchant for the engineering side of music developed through exposure to technical theatre as a member of her high school stage crew and participation in community theatre productions; it was a passion that would stay with her throughout her college years. While attending Arizona State University to receive both a B.A. in Music and a B.A. in Theatre, she was a member of the Sun Devil Marching Band as well as a sound designer for the Department of Theatre. After graduating, Jeanne continued her association with ASU including a position as audio engineer for the ASU Technology Based Learning and Research department, where she was responsible for the recording of location video shoots and audio post production editing. The recipient of two AriZoni awards for theatrical sound design, she was a theatre technician for both Gammage Auditorium and Rhino Staging. She continued her career in broadcasting as program director of Talk One Network, undertaking the production of nationally syndicated talk radio shows. In 2005, Jeanne returned to Arizona PBS in the Broadcast Operations department and has since joined Central Sound as the Producer of Audio Programming.

As a graduate of New York University with a B.M. in Music Technology, he apprenticed for tonmeister Leszek Wojcik at the Carnegie Hall Recording Studio as well as Radio City Music Hall. Afterwards, Leszek took him on as an engineer and he honed his skills working with Chamber Music Society at Lincoln Center, Metropolitan Opera, American Symphony, and many others.
