On the cusp of the 10-year anniversary of her 'Songs in A Minor' album, Alicia Keys took the stage to make the world premiere of her song 'Typewriter' at the 2011 BET Awards, before leading into 'A Woman's Worth' with Bruno Mars and Rick Ross.

Keys delivered the slow and voicey never-before-heard song high above the crowd on a metal platform. 'Typewriter' was first first recorded in 1997, but is just now, in 2011, making itself known to the world on the reissue of Keys' 2001 album.

After a short intro of the song about outdated technology, the New York native stepped down off of her platform to take a seat at the piano where she began to play 'A Woman's Worth,' when out walked Bruno Mars in a clean white suit to join her. Though their duet was nothing short of glorious harmony, it wasn't complete without the help of Rick Ross, who walked on the stage to deliver a quick rap verse and speed up the performance.

Keys' wasn't ready for the curtain to drop without a sampling of the song that made her famous. She played out to the 2001 Grammy-winning hit 'Fallin'' which brought the mood back down from hyped and hip-hoppy to Keys' signature soulful style, letting the BET Awards viewers -- and the world -- know that 10 years is the beginning, not the end, for her.
