King Crimson's Robert Fripp's guitar work can be heard on some of Bowie's earlier work having joined him in the studio to work on 1977 track 'Heroes' and later, the recording of Bowie's 1980 album, Scary Monsters.

As Rolling Stone reports though, Fripp has said he's now entering into a dispute with Bowie's estate as he believes he hasn't been properly credited for his work. Taking to social media, he's said that he should be credited as a "featured player" on two of Bowie's albums.

"This accreditation as a Featured Player is supported by Brian Eno, Tony Visconti, David Bowie himself (although the terminology was not then in use), and the Court Of Public Opinion over four decades," Fripp claims, adding that Bowie's estate hasn't recognised him as a featured player due to the rules of UK music licensing company PPL. He goes on to call their rules "an historic injustice".

Bowie's estate has yet to issue a response to Fripp's post.
