Question: B. F. Shelton recorded a number of songs for which Victor Talking Machine Company producer?

full_context: Document 1: List of record labels from Bristol: The English city of Bristol has, since the mid-1970s, had a particularly fertile music culture, resulting in not only a great many influential musicians and bands, but also its own sound, Bristol sound or trip hop. Along with the music, a number of local record labels also developed, some receiving national and international attention, others with a smaller audience appeal. In the 1970s, there was a DIY culture of record production and the independent record label came to prominence. One of the most successful at that time was Virgin Records started in 1972. Chiswick Records, Stiff Records, Rough Trade Records and Factory Records followed. By the later part of the decade, Virgin had become a part of the music business establishment, and new independent record labels began appearing in virtually every British town and city: Bristol was no exception. One of the very first Bristol punk bands, The Cortinas released its first single on Miles Copeland's Step Forward Records in 1977, eventually moving on to CBS before disbanding. Copeland also released, in 1977, The Pigs' Youthanasia EP on his newly formed New Bristol Records. The explosion in punk/new wave bands forming in the area did not attract interest from the major London-based record labels, so local labels sprung up to release recordings from these groups. Amongst the first, and initially more successful, were Heartbeat Records, Fried Egg Records, Recreational Records and Riot City Records (a Heartbeat subsidiary). Others with more modest success were Wavelength Records (although its subsidiary Bristol Recorder, did achieve some popularity), Circle Records and Sheep Worrying. Some bands set up their own labels: Black Roots (Nubian Records) and Essential Bop (Monopause Records). Yet other labels, although not based in Bristol, had a strong representation of bands from the area: Y Records, Rialto Records and Naïve Records.
Document 2: Music of North Carolina: North Carolina is known particularly for its tradition of old-time music, and many recordings were made in the early 20th century by folk song collector Bascom Lamar Lunsford. Most influentially, North Carolina country musicians like the North Carolina Ramblers and Al Hopkins helped solidify the sound of country music in the late 1920s, while influential bluegrass musicians such as Earl Scruggs, Doc Watson and Del McCoury came from North Carolina. Arthur Smith is the most notable North Carolina musician/entertainer who had the first nationally syndicated television program which featured country music. Smith composed "Guitar Boogie", the all-time best selling guitar instrumental, and "Dueling Banjos", the all-time best selling banjo composition. Country rock star Eric Church from the Hickory area has had 2 #1 albums on the Billboard 200, including "Chief" in 2011. Both North and South Carolina are a hotbed for traditional country blues, especially the style known as the Piedmont blues. Elizabeth Cotten, from Chapel Hill, was active in the American folk music revival.
Document 3: New Jersey Music Hall of Fame: The New Jersey Music Hall of Fame was founded in 2005 in Asbury Park, New Jersey, with plans to construct a building in downtown Asbury Park or closer to the Boardwalk. New Jersey has a rich musical heritage, covering artists from Count Basie to Frank Sinatra to Bruce Springsteen. New Jersey has also played a role in the technology behind music; Thomas Edison invented the record player in the state in 1877, while Les Paul created the solid-body guitar.
Document 4: Grand Ole Opry: The Grand Ole Opry is a weekly country-music stage concert in Nashville, Tennessee, which was founded on November 28, 1925, by George D. Hay as a one-hour radio "barn dance" on WSM. Currently owned and operated by Opry Entertainment (a division of Ryman Hospitality Properties, Inc.), it is the longest-running radio broadcast in US history, albeit not the longest-running one on a radio network. Dedicated to honoring country music and its history, the Opry showcases a mix of famous singers and contemporary chart-toppers performing country, bluegrass, Americana, folk, gospel, and comedic performances and skits. It attracts hundreds of thousands of visitors from around the world and millions of radio and Internet listeners.
Document 5: James Alan Shelton: James Alan Shelton (November 3, 1960 – June 3, 2014) was an American bluegrass guitarist. Shelton was a solo musician, released 10 albums, and performed with the Clinch Mountain Boys.
Document 6: Million Dollar Quartet: "Million Dollar Quartet" is a recording of an impromptu jam session involving Elvis Presley, Jerry Lee Lewis, Carl Perkins, and Johnny Cash made on December 4, 1956, at the Sun Record Studios in Memphis, Tennessee. An article about the session was published in the "Memphis Press-Scimitar" under the title "Million Dollar Quartet". The recording was first released in Europe in 1981 as "The Million Dollar Quartet" with 17 tracks. A few years later more tracks were discovered and released as "The Complete Million Dollar Session". In 1990, the recordings were released in the United States as "Elvis Presley - The Million Dollar Quartet". This session is considered a seminal moment in rock and roll.
Document 7: Sheb Wooley: Shelby Fredrick "Sheb" Wooley (April 10, 1921 – September 16, 2003) was a character actor and singer, best known for his 1958 novelty song "The Purple People Eater." He played Ben Miller, brother of Frank Miller, in the film "High Noon"; played Travis Cobb in "The Outlaw Josey Wales"; and also had a co-starring role as scout Pete Nolan in the television series "Rawhide."
Document 8: G. B. Grayson: Gilliam Banmon Grayson (November 11, 1887 – August 16, 1930) was an American Old-time fiddle player and singer. Mostly blind from infancy, Grayson is chiefly remembered for a series of sides recorded with guitarist Henry Whitter between 1927 and 1930 that would later influence numerous country, bluegrass, and rock musicians. Grayson wrote much of his own material, but was also instrumental in adapting several traditional Appalachian ballads to fiddle and guitar formats. His music has been recorded or performed by musicians such as Bob Dylan, Doc Watson, Mick Jagger, the Kingston Trio, and dozens of bluegrass artists, including the Stanley Brothers and Mac Wiseman.
Document 9: Bristol sessions: 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.
Document 10: Shelor Family: The Shelor Family (also known as Dad Blackard’s Moonshiners) was an American folk music group formed in Meadows of Dan, Virginia in the 1920s. Their music, which was recorded during the Bristol sessions in 1927, had a profound impact on country and bluegrass music. The original family band included Joe Blackard (banjo, vocals), his daughter Clarice (piano, vocals), Jesse Shelor (fiddle, vocals) and Pyrhus Shelor (fiddle), and later resurfaced on an album of field recordings arranged in 1975.
Document 11: B. F. Shelton: 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.
Document 12: Dock Boggs: Moran Lee "Dock" Boggs (February 7, 1898 – February 7, 1971) was an influential old-time singer, songwriter and banjo player. His style of banjo playing, as well as his singing, is considered a unique combination of Appalachian folk music and African-American blues. Contemporary folk musicians and performers consider him a seminal figure, at least in part because of the appearance of two of his recordings from the 1920s, "Sugar Baby" and "Country Blues", on Harry Smith's 1951 collection "Anthology of American Folk Music". Boggs was first recorded in 1927 and again in 1929, although he worked primarily as a coal miner for most of his life. He was "rediscovered" during the folk music revival of the 1960s and spent much of his later life playing at folk music festivals and recording for Folkways Records.
Document 13: Carter Family: The Carter Family is a traditional American folk music group that recorded between 1927 and 1956. Their music had a profound impact on bluegrass, country, Southern Gospel, pop and rock musicians as well as on the U.S. folk revival of the 1960s. They were the first vocal group to become country music stars. Their recordings of songs such as "Wabash Cannonball", "Can the Circle Be Unbroken", "Wildwood Flower", "Keep On the Sunny Side" and "I'm Thinking Tonight of My Blue Eyes" made these songs country standards. The latter's tune was used for Roy Acuff's "The Great Speckled Bird", Hank Thompson's "The Wild Side of Life" and Kitty Wells' "It Wasn't God Who Made Honky Tonk Angels", making the song a hit all over again in other incarnations.
Document 14: Ralph Stanley: Ralph Edmund Stanley (February 25, 1927 – June 23, 2016), also known as Dr. Ralph Stanley, was an American bluegrass artist, known for his distinctive singing and banjo playing. Stanley began playing music in 1946, originally with his brother Carter as part of The Stanley Brothers, and most often as the leader of his band, The Clinch Mountain Boys.
Document 15: Bunt Stephens: John L. "Bunt" Stephens (February 2, 1879 — May 25, 1951), known as Uncle Bunt, was an American Old-time fiddle player. After rising from relative obscurity in 1926 to win a nationwide fiddle contest hosted by automobile magnate Henry Ford, Stephens went on to record several tracks for Columbia Records and made several guest appearances on what would later become the Grand Ole Opry in Nashville before retiring to his farm near Lynchburg, Tennessee. His style of fiddle playing is believed to resemble a style that was popular before the American Civil War.
