David Bowie arrived on U.S. shores in the spring of 1974 to launch the mammoth Diamond Dogs tour, the Broadway-style production inspired by Orwell’s 1984, and his own unnerving trip behind the Iron Curtain. The show was his most elaborate venture to date, epitomizing the dystopian drama that had made him a star. Yet as David spent more and more time in the States, he found himself reconnecting with the music that enthralled him as a young boy: American soul and R&B. This radical departure brought the risk of alienating his fans, who all but worshipped David’s sci fi characters. But with the help of some of the finest funk players of the era — plus a Beatle — it became his biggest success to date. Trading choreographed theater for genuine emotion proved to be a revelation for David, and a major artistic leap forward. But his escalating cocaine use threatened everything: his career, his marriage, and his life.
