Womankind of blue

As a few people said they'd like to see this when I blipped our stairs the other day, here are Lo Jardinièr's terracotta bas-relief heads of jazz singers. Can you recognise them? (he says he won't mind if you can't!) Here's some music by one of them to listen to while you guess.

Hint: Billie Holiday isn't here - as LoJ's favourite jazz singer she has a statuette of her own.

Another one for this week's texture challenge.
