Robert Fripp’s contributions to David Bowie’s Heroes were under the spotlight in a documentary aired on part two of BBC4’s Music Moguls:Masters Of Pop series last night. Producer Tony Visconti, sat at the mixing desk, went through individual tracks, detailing how the song was built up. The segment in the main programme can be found at around 25 minutes.

There’s more detail in this special 20 minute extract of the interview with Tony Visconti in which he describes the three guitar tracks laid down by King Crimson’s other guitarist as that "celestial Fripp sound". The section on Fripp starts at around 4.56.
Heroes is also the subject of this review commissioned by Pitchfork since Bowie’s death.
