Female vocalist recommendations

When it comes to soothing female vocals, lots of great suggestions above. My favorite go to early morning and late night soothing female vocals has to be Helen Merrill, particularly the ‘Helen Merrill with Clifford Brown and Gil Evans’ album. 
 

From the modern era … Melody Gardot and Norah Jones.
