Originally written for Hal McKusick for inclusion on his Jazz Workshop LP recorded in 1956 for RCA Victor Records. Evans mixes an idea in minor that has two influences (a theme from de Falla's ballet El Sombrero de Tres Picos and a Mexican folk song) with a blues in major, and the effect is pure Gil Evans. Despite a large brass ensemble of five trumpets, four trombones (including a bass trombone) and tuba, he used four reeds, of which only one was a saxophone. The other reeds are flutes and bass clarinet. Please note that there is no piano part for this arrangement, and none should be added. From the original manuscript--not a transcription.
