Who Is Esperanza SpaldingWho is Esperanza Spalding? The 26-year-old jazz bassist who snatched the Best New Artist Grammy out of the hands of Justin Bieber, that's who.

Although cameras quickly cut away, Bieber's disappointment at the announcement seemed clear. The AP reports Spalding had just one Grammy nomination entering the show's 53rd annual ceremony Sunday night.

Drake, Mumford & Sons and Florence and the Machine were also nominated. While a lot of people will spend the wake of Bieber's Best New Artist loss figuring out who Spalding is, there's little doubt she's extremely talented.

"From the time Esperanza Spalding appeared on the scene in 2005, the dynamic singer, bassist, composer and arranger has been heralded as jazz's next big thing," the AP wrote in a lead-up to the Grammys. "Her impressive musicianship has won her White House recital dates, praise from the likes of Stevie Wonder and Herbie Hancock, and critical acclaim."
