Isfahan (Persian: اصفهان‎ Esfahān), historically also rendered in English as Ispahan, Sepahan or Hispahan, is the capital of Isfahan Province in Iran, located about 340 km south of Tehran. It has a population of 1,583,609 and is Iran's third largest city after Tehran and Mashhad. The Isfahan metropolitan area had a population of 3,430,353 in the 2006 Census, the second most populous metropolitan area in Iran after Tehran.

The cities of Zarrinshahr, Fooladshahr and Najafabad, Se-deh , Shahin-shahr, Mobarakeh, Falavarjan and chiarmahin all constitute the metropolitan city of Isfahan.

Isfahan is located on the main north-south and east-west routes crossing Iran, and was once one of the largest cities in the world. It flourished from 1050 to 1722, particularly in the 16th century under the Safavid dynasty, when it became the capital of Persia for the second time in its history. Even today, the city retains much of its past glory. It is famous for its Islamic architecture, with many beautiful boulevards, covered bridges, palaces, mosques, and minarets. This led to the Persian proverb "'Esfahān nesf-e jahān ast" (Isfahan is half of the world).

Edward Kennedy "Duke" Ellington (April 29, 1899 – May 24, 1974) was an American composer, pianist, and big-band leader. Ellington wrote over 1,000 compositions. In the opinion of Bob Blumenthal of The Boston Globe "In the century since his birth, there has been no greater composer, American or otherwise, than Edward Kennedy Ellington." A major figure in the history of jazz, Ellington's music stretched into various other genres, including blues, gospel, film scores, popular, and classical. His career spanned more than 50 years and included leading his orchestra, composing an inexhaustible songbook, scoring for movies, composing stage musicals, and world tours. Several of his instrumental works were adapted into songs that became standards. Due to his inventive use of the orchestra, or big band, and thanks to his eloquence and extraordinary charisma, he is generally considered to have elevated the perception of jazz to an art form on a par with other traditional genres of music. His reputation increased after his death and the Pulitzer Prize Board bestowed on him a special posthumous honor in 1999.

John Arnold Griffin III (April 24, 1928 – July 25, 2008) was an American bop and hard bop tenor saxophonist.

Griffin studied music at DuSable High School in Chicago under Walter Dyett, starting out on clarinet before moving on to oboe and then alto sax. While still at high school at age 15, Griffin was playing with T-Bone Walker in a band led by Walker's brother.

Alto saxophone was still his instrument of choice when he joined Lionel Hampton's big band three days after his high school graduation, but Hampton encouraged him to take up the tenor, playing alongside Arnett Cobb. He first appeared on a Los Angeles recording with Hampton's band in 1945 at age 17.

By mid-1947, Griffin and fellow Hampton band member Joe Morris had formed a sextet made up of local musicians, including George Freeman, where he remained for the next two years. His playing can be heard on various early Rhythm and Blues recordings for Atlantic Records. By 1951 Griffin was playing baritone saxophone in an R&B sextet led by former bandmate Arnett Cobb.

Joe Henderson (April 24, 1937 – June 30, 2001) was an American jazz tenor saxophonist. In a career spanning more than forty years Henderson played with many of the leading American players of his day and recorded for several prominent labels, including Blue Note.

From a very large family with five sisters and nine brothers, Henderson was born in Lima, Ohio, and was encouraged by his parents and older brother James T. to study music. He dedicated his first album to them "for being so understanding and tolerant" during his formative years. Early musical interests included drums, piano, saxophone and composition. According to Kenny Dorham, two local piano teachers who went to school with Henderson's brothers and sisters, Richard Patterson and Don Hurless, gave him a knowledge of the piano. He was particularly enamored of his brother's record collection. It seems that a hometown drummer, John Jarette, advised Henderson to listen to musicians like Lester Young, Stan Getz, Dexter Gordon and Charlie Parker. He also liked Flip Phillips, Lee Konitz and the Jazz at the Philharmonic recordings. However, Parker became his greatest inspiration. His first approach to the saxophone was under the tutelage of Herbert Murphy in high school. In this period of time, he wrote several scores for the school band and rock groups.
