Question: B. F. Shelton recorded a number of songs for which Victor Talking Machine Company producer?
Context: Benjamin Frank Shelton (January 1, 1902 – February 28, 1963) was an American singer and banjoist who recorded a number of songs for Victor Records at the Bristol Sessions in Bristol, Tennessee on July 29, 1927.  Shelton traveled from Corbin, Kentucky where he worked as a barber to Bristol for the sessions with gospel singer and preacher Alfred Karnes.  Four of the recordings survive today, "Darling Cora", "Pretty Polly", "Oh Molly Dear" and "Cold Penitentiary Blues".  He recorded again, under the name Frank Shelton, for Columbia Records at the Johnson City Sessions in Johnson City, Tennessee in October 1928, but the recordings were not issued and have not survived. The Chicago Talking Machine Company (sometimes The Talking Machine Company of Chicago, or simply The Talking Machine Company) was a manufacturer and dealer of phonographs, phonograph accessories, and phonograph records from 1892 until 1906, and a major wholesaler of Victor Talking Machine Company products between 1906 and at least 1928. The American Quartet was a four-member vocal group that recorded for various companies in the United States between 1899 and 1925.  The membership varied over the years, but the most famous line-up — comprising John Bieling (first tenor), Billy Murray (second tenor), Steve Porter (baritone), and William F. Hooley (bass) — recorded for the Victor Talking Machine Company from 1909 to 1913.  The same group of singers also recorded for Edison Records as the Premier Quartet (or Quartette), and for that and other labels as the Premier American Quartet.  From 1912 to 1914 the quartet also recorded with countertenor Will Oakland as the Heidelberg Quintet. A partial listing of recording artists who formerly recorded for Victor Talking Machine Company (known in most of the world as Victor Records prior to 1946) include the following list.  Included are artists on Victor's subsidiary label, Bluebird Records. The Russian-American classical virtuoso pianist Vladimir Horowitz was a recording artist for over 60 years; beginning in 1926 on a piano roll system for Welte-Mignon, then with audio recordings, starting in 1928 for the Victor Talking Machine Company, later RCA Victor.  Horowitz continued to record for a variety of record labels throughout his life.  Between 1962 and 1973 he recorded for Columbia Masterworks In 1975, Horowitz returned to RCA, with which he recorded a series of live recitals.  For the last years of his life, between 1985 and 1989, Horowitz recorded for Deutsche Grammophon.  Horowitz’s final recording, with Sony Classical, was completed in November 1989, four days before his death.  This final recording consisted of repertoire that he had never previously recorded. The Bristol Sessions are considered the "Big Bang" of modern country music.  They were held in 1927 in Bristol, Tennessee by Victor Talking Machine Company producer Ralph Peer.  Bristol was one of the stops on a two-month, $60,000 trip that took Peer through several major southern cities and yielded important recordings of blues, ragtime, gospel, ballads, topical songs, and string bands.  The Bristol Sessions marked the commercial debuts of Jimmie Rodgers and the Carter Family.  As a result of the influence of these recording sessions, Bristol has been called the "birthplace of country music".  Since 2014, the town has been home to the Birthplace of Country Music Museum. The Nipper Building is a colloquial name for "The Victor" condominiums, and formerly, Building 17, RCA Victor Company, Camden Plant.  The structure is a historical building located in Cooper Grant neighborhood of Camden, Camden County, New Jersey, United States.  For many years Camden was the headquarters of the Victor Talking Machine Company, later RCA Victor.  Originally a Victrola cabinet factory, the building was converted into luxury apartments and retail space in 2004. The following discography is a work in progress.  Currently it contains all known published recordings by Enrico Caruso made through 1904 and some from his early years recording for the Victor Talking Machine Company in the United States.  The recordings are listed chronologically by recording date, title, composer and matrix number.  A list of unpublished recordings follows the main discography.  When more than one "take" was recorded for a selection, only the published take number appears after the matrix number; occasionally, multiple takes of the same selection have been issued.  If only one take was recorded, no take number is listed after the matrix number.  Matrix numbers should not be confused with catalog numbers. RCA Victrola was a budget record label introduced by RCA Victor in the early 1960s to reissue classical recordings originally released on the RCA Victor "Red Seal" label.  The name "Victrola" came from the early console phonographs first marketed by the Victor Talking Machine Company in 1906.  Many of RCA Victrola's reissues included recordings from the historic RCA Victor "Living Stereo" series first released in 1958, using triple channel stereophonic tapes from as early as 1954.  There were also some first stereo releases of recordings that had previously been available only in monaural versions.  For several years, Victrola released both stereophonic and monaural versions of many albums. Nipper (1884–1895) was a dog, from Bristol, England who served as the model for a painting by Francis Barraud titled His Master's Voice.  This image was the basis for the dog-and-gramophone commercial logo, one of the world's most famous used by several audio recording and associated company brands, including Victor Talking Machine Company, Gramophone Company, Berliner Gramophone, His Master's Voice, HMV, EMI, RCA, RCA Victor, Victrola, Electrola, Bluebird, Zonophone, JVC and Deutsche Grammophon.
