Sarah Vaughan recorded frequently during her three years with Roulette, and all 16 albums she completed for them plus five previously unissued tracks are included in this comprehensive eight-CD boxed set from Mosaic. The gifted singer is heard in a variety of settings, from superb small-group sessions to big-band settings and various dates bordering on easy listening; the sessions omitting the often syrupy string sections are the cream of this bumper crop.
