Problem: 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).

Problem: Background: Louis Thomas Jordan (July 8, 1908 - February 4, 1975) was a pioneering American musician, songwriter and bandleader who was popular from the late 1930s to the early 1950s. Known as "The King of the Jukebox", he was highly popular with both black and white audiences in the later years of the swing era. Jordan was one of the most successful African-American musicians of the 20th century, ranking fifth in the list of the most successful black recording artists according to Joel Whitburn's analysis of Billboard magazine's R&B chart. Though comprehensive sales figures are not available, he had at least four million-selling hits during his career.
Context: Jordan's first band, drawn mainly from members of the Jesse Stone band, was originally a nine-piece group, but he soon scaled it down to a sextet after landing a residency at the Elks Rendezvous club, at 464 Lenox Avenue, in Harlem. The original lineup of the sextet was Jordan (saxes, vocals), Courtney Williams (trumpet), Lem Johnson (tenor sax), Clarence Johnson (piano), Charlie Drayton (bass) and Walter Martin (drums). In his first billing, as Louie Jordan's Elks Rendez-vous Band, his name was spelled Louie so people would know not to pronounce it Lewis.  The new band's first recording date, for Decca Records on December 20, 1938, produced three sides on which they backed an obscure vocalist, Rodney Sturgess, and two novelty sides of their own, "Honey in the Bee Ball" and "Barnacle Bill the Sailor". These recordings were credited to the Elks Rendezvous Band, but Jordan subsequently changed the name to the Tympany Five, since Martin often used tympani in performance. (The word tympany is also an old-fashioned colloquial term meaning "swollen, inflated, puffed-up", etymologically related to timpani, or kettledrums, but historically separate.)  The various lineups of the Tympany Five (which often featured two or three extra players) included Bill Jennings and Carl Hogan on guitar, the renowned pianist-arrangers Wild Bill Davis and Bill Doggett, "Shadow" Wilson and Chris Columbus on drums and Dallas Bartley on bass. Jordan played alto, tenor and baritone saxophone and sang the lead vocal on most songs.  Their next recording date, in March 1939, produced five sides, including "Keep a-Knockin'" (originally recorded in the 1920s and later famously covered by Little Richard), "Sam Jones Done Snagged His Britches" and "Doug the Jitterbug". Lem Johnson subsequently left the group and was replaced by Stafford Simon. Sessions in December 1939 and January 1940 produced two more early Jordan classics, "You're My Meat" and "You Run Your Mouth and I'll Run My Business". Other musicians who passed through the band in 1940 and 1941 included the tenorist Kenneth Hollon (who recorded with Billie Holiday) and the trumpeter Freddie Webster (from Earl Hines's band), who was part of the nascent bebop scene at Minton's Playhouse and influenced Kenny Dorham and Miles Davis.
