The registry, created by an act of Congress in 2000, is dominated by musical recordings, but it also includes other sounds, such as speeches and sounds from the natural world. Recordings must be at least 10 years old to qualify for addition.
Among the classical recordings added this year are a 1930 recording of Beethoven's Egmont Overture by the Modesto (California) High School Band (the only surviving recording from a series of national band competitions); the premiere of Samuel Barber's popular Adagio for Strings, from a 1938 radio broadcast by the NBC Symphony; a 1954 live recording of Berlioz's Damnation of Faust by the BSO; a 1956 recording of Elliott Carter's Variations for Orchestra by the Louisville Orchestra, which commissioned the work; Pome Electronique, a 1958 work for audio tape by Edgard Varese; and Switched On-Bach, the hit 1968 album of the composer's work performed on the Moog synthesizer by Walter Carlos (later Wendy Carlos).
Jazz recordings include trombonist Kid Ory's 1922 "Ory's Creole Trombone," believed to be the first recording issued of a black jazz band; saxophonist Frankie Trumbauer and cornetist Bix Beiderbecke's famed 1927 recording "Singing the Blues"; Count Basie's "One O'Clock Jump," from 1937; Nat "King" Cole's 1943 rendition of "Straighten Up and Fly Right"; and Dave Brubeck's rhythmically adventurous album Time Out from 1959.
Also among the additions this year are a recording of the first transatlantic telephone conversation (1927), the broadcast of the 1938 Joe Louis-Max Schmeling boxing match, and a 1932 recording of the Broadway show Show Boat.
