Question: What kind of group does Dallas Taylor and David Gilmour have in common?
Context: About Face is the second solo studio album by the English guitarist-singer-songwriter David Gilmour.  It was originally released in March 1984, on the label Harvest in the UK, and Columbia in the US.  Co-produced by Bob Ezrin and Gilmour, the album was recorded in 1983, in sessions that took place at Pathé Marconi Studio, in Boulogne-Billancourt, France.  Two tracks, "All Lovers Are Deranged" and the more radio-friendly "Love on the Air", were co-written by Gilmour and his long-time friend Pete Townshend, the main songwriter for The Who (Gilmour composed the music and Townshend wrote the lyrics).  The remainder of the tracks are credited solely to Gilmour.  In May of the same year, fellow Pink Floyd member Roger Waters released his first official solo album "The Pros and Cons of Hitch Hiking". Pink Floyd's David Gilmour or simply David Gilmour is a film by David Gilmour from his 1984 tour from the album "About Face" for Europe.  The film is mainly a concert performance from The Hammersmith Odeon in London in April 1984.  It also features promotional clips.  Lastly, a documentary called "After The Floyd" which followed Gilmour on the 1984 solo tour and includes interviews with David on tour buses (the bus driver referred to David as ex-guitarist of Pink Floyd) and in hotel rooms.  Also included is more live footage of concerts and soundchecks in Europe.  It is now out of production. David Jon Gilmour, {'1': ", '2': ", '3': ", '4': "} (born 6 March 1946) is an English guitarist, singer and songwriter best known as a longtime member of the progressive rock band Pink Floyd.  He joined group as guitarist and co-lead vocalist in 1968, effectively as a replacement for founder member Syd Barrett, who was dismissed from the band shortly afterwards. David Gilmour is the debut solo studio album by Pink Floyd guitarist and co-lead vocalist David Gilmour.  The album was released in May and June 1978 in the United Kingdom and the United States, respectively.  The album reached number 17 in the UK and number 29 on the Billboard US album charts; it was certified Gold in the US by the RIAA.  The album was produced by Gilmour, and consists mostly of blues, guitar oriented rock songs except for the piano-dominated ballad "So Far Away". "Castellorizon" is the opening song on David Gilmour's third solo album, "On an Island".  It is an instrumental guitar solo, which starts off with an overture of various sounds from other tracks of the album before the guitar is introduced.  The song is based on a night Gilmour spent on the Greek island of Kastellorizo.  It segues into "On an Island", the title track.  The song received a nomination for Best Rock Instrumental Performance at the 49th Grammy Awards.  The song was nominated for the same Grammy Award again at the 51st Grammy Awards for a performance from Gilmour's "Live in Gdańsk" album. Dallas Taliaferro Taylor (born May 17, 1980) is an American musician who is the vocalist for the Southern metal band Maylene and the Sons of Disaster.  He is the former vocalist and founder of the American metalcore band Underoath.  He performed on three Underoath albums: "Act of Depression", "Cries of the Past", and "The Changing of Times".  In 2003, Dallas left Underoath, and was replaced by Spencer Chamberlain.  He was born in Ocala, Florida. David Gilmour in Concert is a DVD of Pink Floyd guitarist David Gilmour's solo concert at the Royal Festival Hall, London in June 2001, as part of the Robert Wyatt-curated Meltdown festival.  It also features additional footage recorded during three concerts at the same venue in January 2002.  The track selection includes several Pink Floyd compositions in addition to Gilmour's solo works.  Guest appearances are made by Floyd colleague Richard Wright, as well as Robert Wyatt and Bob Geldof.  It includes the first ever performance of "Smile" a track which would appear almost five years later on Gilmour's third solo album - "On an Island", and Gilmour even plays a few Syd Barrett compositions.  Also included is "Je crois entendre encore " ("I still believe I hear"), an aria from Georges Bizet's opera "Les pêcheurs de perles " ("The Pearl Fishers"), with a libretto by Eugène Cormon and Michel Carré, and sung by Gilmour in the original French. "High Hopes" is the eleventh and final track from the 1994 Pink Floyd album "The Division Bell", composed by David Gilmour with lyrics by Gilmour and Polly Samson.  Its lyrics speak of the things one may have gained and lost in life, written from Gilmour's autobiographic perspective.  Gilmour has said that the song is more about his early days, and leaving his hometown behind, than about the seeds of division supposedly planted in Pink Floyd's early days.  Douglas Adams, a friend of Gilmour, chose the album title from one verse in this song.  Live versions are featured on "Pulse", "Remember That Night" and "Live in Gdańsk".  On "", a somewhat shortened version of the song segues into Syd Barrett's "Bike".  The segue is accomplished by cutting from the church bell at the end of "High Hopes" to a new bicycle bell sound effect before "Bike" begins.  A 7-inch vinyl version of the single was released on a transparent record. Barn Jams are a series of instrumental pieces written by Pink Floyd guitarist, David Gilmour and performed by him and the core members of his 2006 On an Island Tour band, Guy Pratt on bass, Richard Wright on keyboards and Steve DiStanislao on drums.  The sessions were recorded and filmed in a barn at David's home in Sussex, England, in January 2007.  It is unknown how many pieces exist, altrough Gilmour himself, in a bonus interview within the second DVD of his 2008 release "Live in Gdańsk", claims that he and guitarist Phil Manzanera (who co-produced the "On an Island" album) recorded and catalogued "close to 200" jams.  Three tracks were released as part of the "Live in Gdańsk" 4-disc edition, deluxe edition and vinyl edition; one was released on "Remember That Night" (2007) and four more were released on the deluxe edition of Gilmour's 2015 "Rattle That Lock" album.  The "Barn Jams" are the last released recordings made by Richard Wright before his death in 2008. Live in Gdańsk is a live album by David Gilmour.  It is a part of his "On an Island" project which includes an album, tour, DVD, and live album.  It was released on 22 September 2008.  A David Gilmour Signature Series Fender Stratocaster was released at the same time.
