Its departure from the UK digital radio was due to a contractual dispute with Digital One, the owner of the transmission network. Following the exit an online petition was created asking fans of Amazing Radio to back its cause to return to the airwaves.
Sting is standing shoulder to shoulder with new and emerging artists and a growing band of campaigners to bring the commercial-free radio station back.
Originally playing unsigned music only, the station also went on to air music from indie labels. Sting commented: "For some years now I have wondered what shape the music industry might take. How would young musicians and songwriters forge a career? - How might they build an audience?
"It's great to see that Amazing, a company from my home town already with a global reach, is showing a way forward with a music-led solution which seems both fair to musicians and helps build that audience."
Paul Campbell, Amazing Radio CEO, said: "It's awesome that Sting has joined the growing number of people supporting Amazing's mission to help new musicians find an audience.
"Amazing Radio resonates with those with an insight into the future of broadcasting and the music industries."
