Kendra Shank, Mosaic (Challenge). With her previous CD of Abbey Lincoln songs, Shank firmly differentiated herself from the overcrowded current field of women who declare themselves jazz singers. Mosaic takes her a step further. It elevates Shank into the company of the few singers capable of using jazz skills and values to invest a collection of individual songs with story-telling continuity. That happens in classical recitals of art songs. It is rare in jazz and popular music.
