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".

 It segues into "On an Island", the title track.
 The song received a nomination for Best Rock Instrumental Performance at the 49th Grammy Awards.

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.
