Question: 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.

Young left the Basie band in late 1940. He is rumored to have refused to play with the band on Friday, December 13 of that year for superstitious reasons spurring his dismissal, although Young and drummer Jo Jones would later state that his departure had been in the works for months. He subsequently led a number of small groups that often included his brother, drummer Lee Young, for the next couple of years; live and broadcast recordings from this period exist.  During this period Young accompanied the singer Billie Holiday in a couple of studio sessions (during 1937 - 1941 period) and also made a small set of recordings with Nat "King" Cole (their first of several collaborations) in June 1942. His studio recordings are relatively sparse during the 1942 to 1943 period, largely due to the recording ban by the American Federation of Musicians. Small record labels not bound by union contracts continued to record and he recorded some sessions for Harry Lim's Keynote label in 1943.  In December 1943 Young returned to the Basie fold for a 10-month stint, cut short by his being drafted into the army during World War II (see below). Recordings made during this and subsequent periods suggest Young was beginning to make much greater use of a plastic reed, which tended to give his playing a somewhat heavier, breathier tone (although still quite smooth compared to that of many other players). While he never abandoned the cane reed, he used the plastic reed a significant share of the time from 1943 until the end of his life. Another cause for the thickening of his tone around this time was a change in saxophone mouthpiece from a metal Otto Link to an ebonite Brilhart. In August 1944 Young appeared alongside drummer Jo Jones, trumpeter Harry "Sweets" Edison, and fellow tenor saxophonist Illinois Jacquet in Gjon Mili's short film Jammin' the Blues.

Using a quote from the above article, answer the following question: Why did he change to a plastic reed?
HHHHHH
Answer: which tended to give his playing a somewhat heavier, breathier tone

Problem: Birth of the Cool is a compilation album by American jazz musician Miles Davis, released in 1957 on Capitol Records. It compiles eleven tracks recorded by Davis's nonet for the label over the course of three sessions during 1949 and 1950. Featuring unusual instrumentation and several notable musicians, the music consisted of innovative arrangements influenced by classical music techniques such as polyphony, and marked a major development in post-bebop jazz. As the title suggests, these recordings are considered seminal in the history of cool jazz.

The nonet recorded twelve tracks for Capitol during three sessions over the course of nearly a year and a half. Davis, Konitz, Mulligan and Barber were the only musicians who played on all three sessions, though the instrumental lineup was constant (excepting the omission of piano on a few songs and the addition of Hagood on "Darn That Dream"). The first session occurred on January 21, 1949, recording four tracks: Mulligan's "Jeru" and "Godchild" as well as Lewis's "Move" and "Budo". Jazz critic Richard Cook hypothesizes that Capitol, wanting to get a good start, recorded these numbers first because they were the most catchy tunes in the nonet's small repertoire. That date Kai Winding replaced Zwerin on trombone, Al Haig replaced Lewis on piano, and Joe Shulman replaced McKibbon on bass.  The second recording date came three months later on April 22, 1949 with Davis filling in for Fats Navarro in Tadd Dameron's band with Charlie Parker during the interim. The band returned to the studio with five substitutions in personnel: J. J. Johnson on trombone, Sandy Siegelstein on French horn, Nelson Boyd on bass, and Kenny Clarke on drums, and John Lewis returning to piano. At this session, the nonet recorded Mulligan's "Venus de Milo", Lewis's "Rouge", Carisi's "Israel", and "Boplicity", a collaboration between Davis and Evans, credited to the pseudonym "Cleo Henry".  The band did not return to the studio again until March 9, 1950. Davis did not call the band for any rehearsals or live performances between the second and third recording dates. The March 1950 date featured Mulligan's "Darn That Dream", "Rocker", and "Deception", and Evans's arrangement of Chummy MacGregor's "Moon Dreams", which had been released in a jazz arrangement by Glenn Miller and the AAF Band in 1944 on V-Disc. The band saw more substitutions, with Gunther Schuller on French horn and Al McKibbon on bass. Kenny Hagood returned for vocals on "Darn That Dream".
