Jazz's greatest vocalist teams with its most important instrumentalist for this sequel to their celebrated collaboration. Ella Fitzgerald's perfect pitch and impeccable phrasing combine beautifully with Louis Armstrong's gravelly vocals and brilliant trumpet. The chemistry between them is palpable - they clearly delight in each other's company and artistry. The material consists of standards both artists transform through their distinctive interpretations. The arrangements are tasteful, supporting rather than overwhelming the two legends. This is essential vocal jazz demonstrating how great artists elevate each other and how technical perfection and raw emotion can coexist perfectly in music.
