In 1976, David Bowie moved to Berlin and recorded a triptych of albums, Low, "Heroes" and Lodger. Produced in collaboration with Brian Eno and Tony Visconti, they mixed electronic sounds with avant-garde lyrics to produce the most experimental records of Bowie's career.

Since Station to Station, Bowie had worked with the stellar band of Carlos Alomar on guitar, George Murray on bass and Dennis Davis on drums. In mid-1977 they pitched up at Berlin's Hansa Studio, 150 metres from the Berlin Wall, to record "Heroes". The title track features live synth treatments from Brian Eno, pitched guitar feedback from Robert Fripp and a hauntingly intense lead vocal from Bowie, all of which you can hear in glorious isolation in the film above.

Long-time Bowie collaborator Tony Visconti uses high definition transfers of the original, fragile master tapes to break down the title song's individual tracks and tell the the fascinating stories behind its recording.

The "Heroes" album was released on 14 October 1977. Bowie memorably performed the title track 10 years later at the Concert for Berlin, a three-day open-air show in front of the Reichstag. Before playing "Heroes", Bowie addressed the people of East Berlin who had gathered on the other side of the Berlin Wall: "We send our best wishes to all of our friends who are on the other side of the Wall".

In the face of resistance from East German police the crowd's attempts to get closer resulted in 200 arrests, marking the start of two years of escalating unrest which eventually saw the Wall dismantled.
