On this four-CD set are some of Ella Fitzgerald's finest live performances during the years she was managed by Norman Granz. All of the material (which is taken from ten different performances in 1953, 1966, 1967, 1971, 1972, 1974, 1975, 1977, 1979 and 1983) was previously released on various Pablo albums. Since this is a best-of collection and was lovingly put together by the knowledgeable producer Eric Miller, the music is consistently rewarding and emphasizes the interpretive skills, scatting and jazz phrasing of the First Lady of Song. Although mostly backed by her trio/quartets of the period, Ella does get to jam "Perdido" with the 1953 JATP All-Stars, is backed by the Duke Ellington and Count Basie Orchestras on some songs and revisits "Flying Home" with an all-star group in 1983. The most remarkable performance is 1972's "C Jam Blues" which features Ella trading off remarkable musical jokes with Al Grey, Stan Getz, Harry "Sweets" Edison, Eddie "Lockjaw" Davis and Roy Eldridge.
