A new David Bowie documentary, David Bowie: The Last Five Years, is coming to the BBC on January 7. The doc, a follow-up to David Bowie: Five Years, will explore Bowie’s final albums, The Next Day and Blackstar, as well as the musical Lazarus. It features unseen archive footage, unreleased Bowie interviews, and input from his friends and collaborators, as well as an exclusive recording of Bowie’s original vocal for “Lazarus.” U.K. viewers can watch a trailer here. Next month, BBC Four will also broadcast “Bowie at the BBC,” which compiles rare archive clips of Bowie performances from 1964-2016. There will be several BBC radio tributes throughout January, the month that would have seen Bowie’s 70th birthday.

In the film, Tony Visconti opens up about Bowie’s recording of “Lazarus”:

He would stand in front of the mic and for the four or five minutes he was singing he would pour his heart out. I could see through the window he was really feeling it. The audio picked up his breathing, it wasn’t that he was out of breath, he was hyperventilating in a way, getting his energy up to sing this.
