Los Colores de Fiesta was commissioned by the Pride of San Antonio Show Band to celebrate the year-long 300th Anniversary of city of San Antonio, Texas. The piece was composed in March and April of 2018 and was premiered by the band on June 16, 2018. Composer Charles Booker grew up in San Antonio and experienced the annual festival "Fiesta" that the city celebrates every year in April. As a former member of the South San Antonio and John Jay High School Bands, and later with the 5th Army Band, Mr. Booker marched in the annual Fiesta parade known as the "Fiesta Flambeau Parade", America's largest illuminated night parade and the highlight of Fiesta! The colorful "Fiesta San Antonio" started in 1891 as a one parade event to honor the heroes of the Alamo and the Battle of San Jacinto. It has evolved into one of this nation's premier festivals and the funds raised by official Fiesta events provide services to San Antonio citizens throughout the year. That commemoration still takes place, but for more than a century, Fiesta has grown into an exciting celebration of San Antonio's rich and diverse cultures.
