Sarah Vaughan's voice brought to jazz an unprecedented combination of attractive characteristics. A rich, beautifully controlled tone and vibrato, the ability to treat her voice more as a jazz instrument than as a vehicle for lyrics, and a musician's ear for harmony. Her early work featured in this Proper box set represents some of the finest moments of Sassy's long career, marked by a purity of voice and performance that would not be achieved again. The 4 CD set comes with a 44 page booklet including Sassy's story, rare pictures and discography.
