Tony Visconti has been producing David Bowie's albums since Space Oddity in 1969. They've worked together on many of Bowie's greatest triumphs, including Heroes, Young Americans and Scary Monsters. After a long break, they joined forces again in the early 2000s for Heathen and Reality. Two years ago, he started working with Bowie on his long-awaited new album, The Next Day. Rolling Stone spoke to Visconti about the pair's secret sessions, how medieval English history inspired some of the songs and why it's unlikely that Bowie will tour – though a single show remains possible. As the producer noted, his other longtime collaborator, Morrissey, has the opposite plan. . . but he'll get to that.
