Dianna Reeves

Among non-questionable favorites, like vocal legend Ella Fitzgerald, Frank Sinatra, Rosemary Clooney, Dianne Reeves has her valuable place in my heart. Recognized as one of jazz's pre-eminent vocalists, Dianne Reeves is one of the most significant singers in jazz.

Reeves was featured with the Lincoln Center Jazz Orchestra for several Duke Ellington projects in celebration of Ellington's Centennial. A recording with Daniel Barenboim and the Chicago Symphony, and a concert appearance at Carnegie Hall with Sir Simon Rattle and the Orchestra of St. Lukes were among her appearances associated with the Ellington Centennial salute.

She has to date won 4 Grammy Awards for "Best Jazz Vocal Performance" for her albums
2001 In the Moment - Live In Concert
2002 The Calling: Celebrating Sarah Vaughan
2003 A Little Moonlight
2006 Good Night, and Good Luck (Soundtrack)
She is the only singer to have won this Grammy for three consecutive recordings.

Actually I like her 2003 video recording. 
Her permanent musical partner and Musical Director - pianist Peter Martin plays fabulously – no doubt currently he is one of the best accompanist in jazz. Just listen and enjoy to the two outstanding musicians short video-clip - Skylark (Carmichael, Mercer) Duration: 6:52
