Haunted Heart is the debut of the "other" Renee Fleming ? the smoky chanteuse lurking behind America´s most prominent operatic soprano. It is a transformation so organic and whole that it may astonish even those who already know of Fleming´s history with jazz singing. Make no mistake: this is not "Renée sings Jazz" in the vein of "Kiri Sings Cole Porter," or even "Dawn Upshaw Sings Rodgers and Hart." This is not an operatic voice in wonderland. It is a new voice, the voice of an entirely different musical persona, and on its own terms something quite successful.
