It would have been very easy for David Bowie to squeeze out glam albums like Ziggy Stardust and Aladdin Sane for years and years, but he knew to be a truly great artist he had to challenge his fans and move into different areas. With that in mind, he put all of his past music aside and started work on a Philly R&B style album. A young soul singer named Luther Vandross was taped for background vocals, and his new friend John Lennon helped Bowie write "Fame." The result was Young Americans. Some old fans were turned off, but the huge radio hits "Fame" and "Young Americans" introduced him to a whole new audience.
