'The next 50 is here:' the 50th GRAMMYs promotional photo card featuring Alicia Keys (48 of 50) from 2008.

On February 10, 2008 the 50th Annual Grammy Awards took place at the Staples Center in Los Angeles. Earlier in the month, Alicia performed “No One,” from her latest album “As I Am” released the prior year in November, including other hits at the Super Bowl XXLII in Arizona. Her “As I Am Tour” would commence later in the month, touring world-wide into December.

The big 50th honored The Recording Academy’s legacy and paid tribute to its future with a list of honorees and performers. The primary ceremonies were televised in the US on CBS. Alicia was the evening's opening musician, duetting on piano with a half-century old clip of Frank Sinatra for "Learnin' The Blues.”

Late English singer-songwriter Amy Winehouse won a total of five awards that night, including Best New Artist as well as Record Of The Year and Song Of The Year for “Rehab,” while Kanye West took home four, including Best Rap Album for Graduation.

Alicia’s “No One” won her Best Female R&B Vocal Performance, winning over Jill Scott and Mary J. Blige, and for Best R&B Song.

She returned to the stage to perform "No One,” lifting the audience higher as she brought out guitarist John Mayer onstage for a melodic guitar solo.
