Digesting the music of Duke Ellington's revolutionary "jungle" period is a complicated pursuit because he recorded multiple arrangements for a number of labels between 1927 and 1932. Sony owns his OKeh and Columbia cuts (found on these two CDs), BMG owns his Victor sides, and Decca owns his Brunswick and Vocalion work (issued on the three-CD Early Ellington). All of them contain readings of standout compositions like "Black and Tan Fantasy," "East St. Louis Toodle-oo," "Black Beauty," "The Mooche," "Mood Indigo," and "Rockin' in Rhythm." The OKeh package lacks versions of "Solitude" and "Creole Love Call," but offers some noteworthy exclusives: superb solo stride-piano versions of "Black Beauty" and "Swampy River"; Jabbo Smith's wonderful trumpet solo on a 1927 version of "Black and Tan Fantasy" as a game-day replacement for "indisposed" co-composer Bubber Miley; and the first recording of "The Mooche," with Miley in control and guitarist Lonnie Johnson augmenting an already formidable lineup that includes Tricky Sam Nanton, Barney Bigard, Harry Carney, and Johnny Hodges. Even when a star like trumpet-growl pioneer Miley moved on, Cootie Williams would more than fill the gap. Musically, Ellington brought jazz to new levels of sophistication, complexity, and emotional depth during this first great period, synthesizing the classic New Orleans sound with a vibrant theatrical element and a dynamic rhythmic impulse. --Marc Greilsamer
