Bearing witness to the production surrounding singer-songwriter/producer John Legend's Sessions performance last month, you can't help but marvel at the success of the Grammy-winning crooner, who burst on the scene with his debut album, 'Get Lifted,' just four years ago. Now, Legend is already on his third studio album, 'Evolver,' which hit stores Oct. 28.

Just a few years after Legend's critically-acclaimed debut, the singer finds himself in a very comfortable position. He's confident in his ability to deliver the best of what his fanbase loves: romantic, piano-laced ballads, and a little of the unexpected -- i.e. 'Greenlight,' the first single off 'Evolver.' OutKast's Andre 3000 joins the singer on the dance track and teases the 'Ordinary People' pianist.

"Sometimes you gotta step from behind that piano and let 'em know what's going on. Even Stevie Wonder got down sometimes," Dre jokes at the end of the song. Legend doesn't disappoint and makes sure to step from behind the piano while in our New York studio. But don't fret -- he stays true to form and sits at the keys for the slower 'Evolver' tunes like 'Good Morning' and 'Everybody Knows.'
