Legendary producer is in talks to ensure material comes out.

American record producer Tony Visconti, who worked with David Bowie for over 40 years, has told the Evening Standard that he is working on releasing unheard Bowie material.

“I think it’s logical that, over the next few years, you’re going to hear a lot of stuff that you haven’t heard before,” Visconti told the newspaper. “I’m in talks with his management and his label – there’s going to be some great Bowie stuff coming out.”

Bowie had recorded five other new tracks, intended for a follow-up to his final album Blackstar, before his death. “I haven’t heard those songs yet,” Visconti said. “I might actually have to help his managerial company to find them. I have an idea where he might have recorded them, but there is also a lot of unreleased material from many albums.”

A second boxset of unreleased Bowie material, following 2015’s Five Years, could see a release this autumn.

The British artist left behind a wealth of recorded and unheard material. Some of this unheard music will be the focus of a BBC4 documentary, The People’s History Of Pop, to be aired in July. The show’s presenter, Danny Baker, let out on Twitter that he had been played a demo of ‘Space Oddity’ with alternative lyrics and a version of ‘My Way’ which inspired the hit ‘Life On Mars?’.

In 2011, Visconti sat down for an extensive lecture at the Red Bull Music Academy about his career and his collaboration with Bowie which began with his second album in 1969 and lasted until his death. Visconti was involved in the famous Berlin trilogy of albums Bowie released in the late 1970s.
