You know the songs by heart. You cheered her on as she won all those Grammys. You've sobbed your guts out to "Someone Like You" more times than you care to admit. But how well do you really know 21? Adele's sophomore album has been a smashing success for many reasons, not the least of which is the young lady herself -- her ability to speak so frankly and beautifully to so many people through her songs, and that gut-grabbing, rafters-shaking voice of hers.
Almost as important, however, is the album's distinctive style, a rich palette equal parts vintage and contemporary, soul and rock 'n' roll, vulnerability and fierceness. In other words, it's ripe for a little Source Material mining, and that's just what we've done here, taking a deep dive into the musical world that made 21 -- and Adele -- the magnificent creatures they are.
