Background: Lester Willis Young (August 27, 1909 - March 15, 1959), nicknamed "Pres" or "Prez", was an American jazz tenor saxophonist and occasional clarinetist. Coming to prominence while a member of Count Basie's orchestra, Young was one of the most influential players on his instrument. In contrast to many of his hard-driving peers, Young played with a relaxed, cool tone and used sophisticated harmonies, using what one critic called "a free-floating style, wheeling and diving like a gull, banking with low, funky riffs that pleased dancers and listeners alike". Known for his hip, introverted style, he invented or popularized much of the hipster jargon which came to be associated with the music.
Context: In 1933 Young settled in Kansas City, where after playing briefly in several bands, he rose to prominence with Count Basie. His playing in the Basie band was characterized by a relaxed style which contrasted sharply with the more forceful approach of Coleman Hawkins, the dominant tenor sax player of the day. One of Young's key influences was Frank Trumbauer, who came to prominence in the 1920s with Paul Whiteman and played the C-melody saxophone (between the alto and tenor in pitch).  Young left the Basie band to replace Hawkins in Fletcher Henderson's orchestra. He soon left Henderson to play in the Andy Kirk band (for six months) before returning to Basie. While with Basie, Young made small-group recordings for Milt Gabler's Commodore Records, The Kansas City Sessions. Although they were recorded in New York (in 1938, with a reunion in 1944), they are named after the group, the Kansas City Seven, and comprised Buck Clayton, Dicky Wells, Basie, Young, Freddie Green, Rodney Richardson, and Jo Jones. Young played clarinet as well as tenor in these sessions. Young is described as playing the clarinet in a "liquid, nervous style."  As well as the Kansas City Sessions, his clarinet work from 1938-39 is documented on recordings with Basie, Billie Holiday, Basie small groups, and the organist Glenn Hardman. Billie and Lester met at a Harlem jam session in the early 30s and worked together in the Count Basie band and in nightclubs on New York's 52nd St. At one point Lester moved into the apartment Billie shared with her mother, Sadie Fagan. Holiday always insisted their relationship was strictly platonic. She gave Lester the nickname "Prez" after President Franklin Roosevelt, the "greatest man around" in Billie's mind. Playing on her name, he would call her "Lady Day." Their famously empathetic classic recordings with Teddy Wilson date from this era.  After Young's clarinet was stolen in 1939, he abandoned the instrument until about 1957. That year Norman Granz gave him one and urged him to play it (with far different results at that stage in Young's life--see below).
