'Life On Mars' (1971)
David Bowie was looking like a possible one-hit wonder by the time Hunky Dory came out in late 1971. His previous album The Man Who Sold the World didn't score a hit, and "Space Oddity" was now over two years old. But Bowie really stepped up his songwriting game with this album, writing such classics as "Changes," "Queen Bitch" and "Life On Mars." It took the release of his next album for a mass audience to discover the brilliance of Hunky Dory, but ever since then it's been regarded as one his finest works. Here's the video for "Life on Mars," featuring Rick Wakeman on keyboards shortly before he joined Yes.
