Billie Holiday I find emotionally wrenching, especially the "Lady In Satin" album.
Jimmy Scott KILLS me. Not just his recordings (which are extraordinary -- "Imagination," "The Folks Who Live on the Hill," and "Nothing Compares To You" can reduce me to tears), but live as well. I saw him perform "All the Way" once in nightclub filled with jaded New Yorkers and he literally reduced the entire room to tears -- including the bartender and the waitress (who had to set down her tray of drinks, wipe her eyes and compose herself before she could get back to her job afterwards).
Nina Simone is another one I've seen wipe out a room full of people. I saw her in Boston back around 1990 give her first concert in America in over a decade. She was absolutely brilliant and for an encore she emerged to the standing ovation, dismissed her band with a wave of her hand, sat down at the piano and gave the most intense rendition of "Ne Me Quitte Pas" imaginable. I don't think anyone breathed for the four minutes of the song. When she finished, another standing ovation (with most of the audience in tears) and she left the stage and didn't return for another bow.
I was also just listening to Dorothy Loudon's recording of "50 Percent" and could barely breath by the end.
I should mention Maria Callas (especially Norma, Traviata, Tosca, Puritani, and Lucia) and Leontyne Price (Aida, Butterfly, Trovatore, and Porgy & Bess) as two from the opera world who give me chills every time I hear them.
