Joe Gueron

Jacqui Naylor, Lisa Dillan, Janis Ian, Muse, Rita Lee, Jacintha, Zoe Fitz Gerald Carter, Joycelyn Scofield, Gabi Hartmann, Renee Dominique, Lady Blackbird, Karen Souza, Clare Teal, Jnae, Jane Morgan, Salena Jones. Some of these may only have one or two really good songs but I included them because they hit at least one song out of the park.... Like Rebecca Pidgeon, every song of hers can't be a Spanish Harlem. If you aren't sure why they were included give me their name and I will give you at least one song to look at.

Daves true story, Primrose path, Somi Masekela, Cheryl Ben tyne, Luba Mason Chritina Perri, Brenda Boykin, Anette Askvik, Imelda May, Amanda Martinez. The rest of 25.

If you can listen in non English, this lady will not have many challengers. Wait till she really sings:

Silje Nerguard, Sophie Milman, Kimberose, Jamie Drake Mandy Barnett, Presilisa, Lisa Ono, Niki King, Rumer, Roberta Gambarini, Helen Schneider, Shook Twins, Hailie Loren, Peggy Lee, Melody Gardot, Ann Hampton Calloway, Lana Del Rey, Inger Marie Gundersen, Stina Foster, Helen Merrill, Nellie McKay, Jazzystics, Aurora, Franqoise Hardy, Kitty Cleveland, Sylvia Brooks. Here are 25 more and I haven't mentioned the greatest of them all... Julie London. Her song from Sharkey's machine.... "My funny Valentine" appears to be a combination of Doc Severen's introduction and Julie London's song added afterwards... It was great but it was hard to figure out what was done to make the recording in the movie sound like that. I could be wrong though.
