Question: Which musician's recordings did Clarence white appear on?
Context: Roadmaster is a country rock album by Gene Clark released in 1973.  The album was compiled from various unreleased recordings for A&M Records made in 1970 through 1972.  Eight tracks yielded from an April 1972 recording session featuring Clarence White, Chris Ethridge, Spooner Oldham, Sneaky Pete Kleinow, Byron Berline and Michael Clarke; two tracks ("One in A Hundred" and "She's the Kind of Girl") derived from an unissued single reassembling the five original Byrds prior to their 1973 reunion album; and the remaining track, "Here Tonight", had been recorded with The Flying Burrito Brothers.  Initially released in the Netherlands and Germany only on the A&M subsidiary Ariola, it was reissued on compact disc for the American market in 1994. Swampwater was an American country rock band, that formed and started out initially as Linda Ronstadt’s backing group in the late 1960s, soon after she went solo.  They are famous for incorporating cajun and swamp rock elements into their music.  Its members included cajun fiddler Gib Guilbeau, John Beland, before either of them joined The Flying Burrito Brothers, with Stan Pratt, Thad Maxwell, and Eric White (Clarence White of The Byrds' brother).  Swampwater would go on to back Ronstadt in 1971 on TV's "The Johnny Cash Show", and their appearance on the show would help Swampwater secure a recording contract with RCA. Treasures Untold is the title of a live recording by Doc Watson & Family, recorded at the 1964 Newport Folk Festival.  It includes four duets with Clarence White.  Watson's son, Merle, was 15 years old at the time of the recording.  He later performed numerous concerts and on recordings with his father. Clarence White (born Clarence Joseph LeBlanc; June 7, 1944 – July 14, 1973), was an American bluegrass and country guitarist and singer.  He is best known as a member of the bluegrass ensemble the Kentucky Colonels and the rock band the Byrds, as well as for being a pioneer of the musical genre of country rock during the late 1960s.  White also worked extensively as a session musician, appearing on recordings by the Everly Brothers, Joe Cocker, Ricky Nelson, Pat Boone, the Monkees, Randy Newman, Gene Clark, Linda Ronstadt, Arlo Guthrie, and Jackson Browne amongst others.  Together with frequent collaborator Gene Parsons, he invented the B-Bender, a guitar accessory that enables a player to mechanically bend the B-string up a whole tone and emulate the sound of a pedal steel guitar.  White was inducted into the International Bluegrass Music Association Hall of Fame in 2016. Mr. Gone is the ninth album by Weather Report, recorded and released in 1978.  As the group was still looking for a drummer following the departure of Alex Acuña, outside drummers Tony Williams and Steve Gadd appear along with Peter Erskine, who would become Acuña's replacement.  Singers Deniece Williams and Maurice White appear on the final track, "And Then."  Jaco Pastorius's song title "Punk Jazz" would later become the title for a posthumous compilation of his music. Nashville West was a short-lived American country rock quartet that was briefly together in the late 1960s.  The group comprised multi-instrumentalist Gene Parsons, guitarist Clarence White, singer-guitarist-fiddler Gib Guilbeau and bassist Wayne Moore.  Parsons and White left the band to join The Byrds while Guilbeau and Parsons later joined the Flying Burrito Brothers. Kindling is the debut solo album by Country rock musician Gene Parsons recorded in 1973.  Guest musicians on this album include former Byrds bandmate Clarence White, plus Vassar Clements, Ralph Stanley, Bill Payne, and Gib Guilbeau. Joe Cocker, OBE (20 May 1944 – 22 December 2014), born as John Robert Cocker, was an English singer and musician.  He was known for his gritty voice, spasmodic body movement in performance and definitive versions of popular songs of varying genre. Gene Victor Parsons (born September 4, 1944 in Morongo Valley, California) is an American drummer, banjo player, guitarist, singer-songwriter, and engineer, best known for his work with The Byrds from 1968 to 1972.  Parsons has also released solo albums and played in bands including Nashville West, The Flying Burrito Brothers, and Parsons Green.  He is credited with inventing the B-Bender (also known as the StringBender) along with guitarist Clarence White and the device is often referred to as the Parsons/White B-Bender, a trademarked name. Arlen Roth (born October 30, 1952 in New York, U.S.) is an American guitarist, recording artist, performer, tutor, and author.  His first solo album won the Montreux Critics' Award for Best Instrumental Album of the Year in 1978.  He was a regular columnist for Guitar Player magazine from 1982 to 1992.  He has performed and recorded with artists such as Bob Dylan, Danny Gatton, John Entwistle, John Prine, Kate Taylor, James Taylor, Livingston Taylor,  John Sebastian, Rick Wakeman, Paul Simon (as well as Simon and Garfunkel), Ry Cooder, David Lindley, Sonny Landreth, Levon Helm, Bill Kirchen, Duane Eddy, Steve Morse, Albert Lee, and Phoebe Snow.  Roth is a Telecaster enthusiast, and has written the book "Masters of the Telecaster", which details the techniques and licks of many famous Telecaster guitar players.  As a solo artist Roth performs frequently with his younger daughter, Lexie Roth, a recording artist, performer, and songwriter in her own right.  He was greatly influenced by Clarence White of The Byrds' string bending style, but at the age of 14, he did not know White had invented a "B-string bender" for his Telecaster, so Roth developed a new style of doing this with fingers alone.  He thus innovated many string-bending styles on the guitar, simulating a "pedal steel" guitar.  He is also an innovator in the use of "harmonics" within guitar playing.
