In 2019 it was estimated it drew a record-breaking crowd of more than 15,000 people.
Popular acts included electronic group N-Trance and Prodigy tribute band Jilted Generation.
This year organisers say they aim to give music lovers and musicians as close to a festival experience as possible over the airwaves - while raising funds for future festivals.
The three organisations running it, Windrush Radio, charity Guideposts Trust and Witney Music Festival, are at the heart of the town and want the free event to reach as diverse a range of people as possible.
Windrush Radio works with many local organisations from Witney Pride to the Witney Beer Festival, and over the past year has drawn the town together with their daily Covid round-up.
