Gorilla Tapes was the collective name of British Scratch Video artists Jon Dovey (b 1955), Gavin Hodge (b 1954) and Tim Morrison (b. 1955).
 'Scratch' is the art of 'sampling' and repeating found images and sounds, thereby making a new work.
 With simple video editing equipment and images recorded from television, during the mid-1980s Gorilla Tapes made sharp satirical and political videos collaged from old film footage and the TV news imagery of the mid-Thatcher years.
 Gorilla Tapes have exhibited internationally in solo and group exhibitions.
 Highlights include participation in Tate Britain's A Century of Artists Films (2003).

The New Basement Tapes is an American/British musical supergroup made up of members Jim James, Elvis Costello, Marcus Mumford, Taylor Goldsmith, and Rhiannon Giddens.
 The group is best known for "", their 2014 album which consists of tracks based on newly uncovered lyrics handwritten by Bob Dylan in 1967 during the recording of his 1975 album with The Band, "The Basement Tapes".
 The group is also featured in the 2014 Showtime documentary "Lost Songs: The Basement Tapes Continued".
"One" is a song by Irish rock band U2.
 It is the third track from their 1991 album "Achtung Baby", and it was released as the record's third single in February 1992.
 During the album's recording sessions at Hansa Studios in Berlin, conflict arose between the band members over the direction of U2's sound and the quality of their material.
 Tensions almost prompted the band to break up until they achieved a breakthrough with the improvisation of "One"; the song was written after the band members were inspired by a chord progression that guitarist the Edge was playing in the studio.
 The lyrics, written by lead singer Bono, were inspired by the band members' fractured relationships and the German reunification.
 Although the lyrics ostensibly describe "disunity", they have been interpreted in other ways.
From the Sky Down is a 2011 American documentary film directed by Davis Guggenheim about rock band U2 and the production of their 1991 album "Achtung Baby".
 The film documents the album's difficult recording period, the band members' relationships, and the group's creative process.
 Guggenheim, who was commissioned by U2 to create the film to commemorate the record's 20th anniversary, spent several months in 2011 developing the documentary.
 The band were filmed during a return visit to Hansa Studios in Berlin where parts of the album were recorded, and during rehearsals in Winnipeg for the Glastonbury Festival 2011.
 The film contains unreleased scenes from the group's 1988 motion picture "Rattle and Hum", along with archival footage and stills from the "Achtung Baby" recording sessions.
 Development of the album's emblematic song "One" is recounted through the replaying of old recording tapes.
"Ça ira " (French: "it'll be fine") is an emblematic song of the French Revolution, first heard in May 1790.
 It underwent several changes in wording, all of which used the title words as part of the refrain.
Born in Albenga, Fasano spent his childhood in Alassio and studied singing and composition with Pippo Barzizza.
 He debuted at 15 years old recording some songs for a small local label.
Gene Adam was the original singer of Iced Earth/Purgatory.
 Adam joined Purgatory in 1985 and performed many shows with them, as well as recording several demo tapes.
 In 1988, the band changed their name to Iced Earth and added Randall Shawver as a second guitarist.
 Adam wrote the lyrics to "Written On The Walls", the only Iced Earth song he is noted as co-writing.
 The band began working on demos in 1988 and released their first official demo tape "Enter The Realm" in 1989, followed by the self-titled Iced Earth album in 1990.
 Gene continued to perform many shows with the band, notably touring Germany in early 1991 as support for Blind Guardian.
"Where the Streets Have No Name" is a song by Irish rock band U2.
 It is the opening track from their 1987 album "The Joshua Tree" and was released as the album's third single in August 1987.
 The song's hook is a repeating guitar arpeggio using a delay effect, played during the song's introduction and again at the end.
 Lead vocalist Bono wrote the lyrics in response to the notion that it is possible to identify a person's religion and income based on the street on which they lived, particularly in Belfast.
 During the band's difficulties recording the song, producer Brian Eno considered erasing the song's tapes to have them start from scratch.
