Ruth Naomi Floyd, Root to the Fruit (Contour). Ms. Floyd is a Philadelphia church singer whose jazz connections and finely tuned musicianship are as organic to her art as are her Christian convictions. In her fifth album, she leads ten musicians including saxophonist Gary Thomas, drummer Ralph Peterson, bassist Tyrone Brown and the incredible flutist James Newton. Songs like “Mere Breath” and “The Bottle of Tears” disclose her as a solid composer and lyricist whose work holds up well in the company of pieces by Randy Weston, Mary Lou Williams and AntonÃn DvoÅ™Ã¡k. The control, phrasing and inflections of her creamy mezzo-soprano voice make Ms. Floyd one of the most compelling singers of the day, regardless of idiom.
