"Manteca" is one of the earliest foundational tunes of Afro-Cuban jazz. Co-written by Dizzy Gillespie, Chano Pozo and Gil Fuller in 1947, it is among the most famous of Gillespie's recordings (along with the earlier "A Night in Tunisia") and is "one of the most important records ever made in the United States", according to Gary Giddins of The Village Voice. "Manteca" is the first tune rhythmically based on the clave to become a jazz standard. History In 1947, Gillespie asked Mario Bauzá to recommend a Cuban percussionist for his big band. Bauzá suggested Pozo, a rough-living percussionist already famous in Cuba, and Gillespie hired him. They began to work Pozo's Cuban-style percussion into the band's arrangements. The band was touring in California when Pozo presented Gillespie with the idea for the tune. It featured a bridge of two eight-bar trumpet statements by Gillespie, percussion patterns played by Pozo, and horn lines from Gillespie's big band arranger Walter "Gil" Fuller. According to Gillespie, Pozo composed the layered, contrapuntal guajeos (Afro-Cuban ostinatos) of the A section and the introduction, while Gillespie wrote the bridge. Gillespie recounted: "If I'd let it go like [Pozo] wanted it, it would have been strictly Afro-Cuban all the way. There wouldn't have been a bridge. I thought I was writing an eight-bar bridge, but after eight bars I hadn't resolved back to B-flat, so I had to keep going and ended up writing a sixteen-bar bridge." The rhythm of the 'A' section melody is identical to a common mambo bell pattern: Early performances of "Manteca" reveal that despite their enthusiasm for collaborating, Gillespie and Pozo were not very familiar with each other's music. The members of Gillespie's band were unaccustomed to guajeos, overly swinging and accenting them in an atypical fashion. Thomas Owens observes: "Once the theme ends and the improvisation begins... Gillespie and the full band continue the bebop mood, using swing eighths in spite of Pozo's continuing even eighths, until the final A section of the theme returns. Complete assimilation of Afro-Cuban rhythms and improvisations on a harmonic ostinato was still a few years away for the beboppers in 1947." "Manteca" was first performed by the big band at Carnegie Hall on September 29, 1947; it was very well received. The big band recorded the tune on December 22, 1947, and in early 1948 they toured Europe for a few months, without including the
