Question: What culture's arrival in the country the performer of Privilege is a citizen of is known as the "Davidian Revolution"?

full_context: Document 1: I Com: Most of the tracks on the album were produced by Miss Kittin with either Thies Mynther and Tobi Neumann (producers of Chicks On Speed). House music vocalist L.A. Williams raps on track "Requiem for a Hit", the album's second single.
Document 2: Normans: Normans came into Scotland, building castles and founding noble families who would provide some future kings, such as Robert the Bruce, as well as founding a considerable number of the Scottish clans. King David I of Scotland, whose elder brother Alexander I had married Sybilla of Normandy, was instrumental in introducing Normans and Norman culture to Scotland, part of the process some scholars call the "Davidian Revolution". Having spent time at the court of Henry I of England (married to David's sister Maud of Scotland), and needing them to wrestle the kingdom from his half-brother Máel Coluim mac Alaxandair, David had to reward many with lands. The process was continued under David's successors, most intensely of all under William the Lion. The Norman-derived feudal system was applied in varying degrees to most of Scotland. Scottish families of the names Bruce, Gray, Ramsay, Fraser, Ogilvie, Montgomery, Sinclair, Pollock, Burnard, Douglas and Gordon to name but a few, and including the later royal House of Stewart, can all be traced back to Norman ancestry.
Document 3: Privilege (Ivor Cutler album): Privilege is an album by Ivor Cutler, originally released in 1983 on Rough Trade Records. It was produced by David Toop and Steve Beresford, both of whom are better known for their work in improvisational music and, unlike Cutler's 1970s recordings, it sees Cutler's vocals accompanied by a wide range of musical instruments including keyboards, banjo, euphonium and alto flute. The LP is co-credited to Linda Hirst, who recites a number of poems and provides vocals on some of the tracks. The closing track, "Women of the World", was released as a single and became a minor hit on the UK Indie Chart. It has since been covered by Jim O'Rourke, on his 1999 album "Eureka", and YACHT, on their 2007 album "I Believe In You. Your Magic Is Real."
Document 4: A cappella: The Swingle Singers used nonsense words to sound like instruments, but have been known to produce non-verbal versions of musical instruments. Like the other groups, examples of their music can be found on YouTube. Beatboxing, more accurately known as vocal percussion, is a technique used in a cappella music popularized by the hip-hop community, where rap is often performed a cappella also. The advent of vocal percussion added new dimensions to the a cappella genre and has become very prevalent in modern arrangements. Petra Haden used a four-track recorder to produce an a cappella version of The Who Sell Out including the instruments and fake advertisements on her album Petra Haden Sings: The Who Sell Out in 2005. Haden has also released a cappella versions of Journey's "Don't Stop Believin'", The Beach Boys' "God Only Knows" and Michael Jackson's "Thriller". In 2009, Toyota commissioned Haden to perform three songs for television commercials for the third-generation Toyota Prius, including an a cappella version of The Bellamy Brothers' 1970s song "Let Your Love Flow".[citation needed]
Document 5: Eton College: In recent years, the School has put on a musical version of The Bacchae (October 2009) as well as productions of A Funny Thing Happened on the Way to the Forum (May 2010), The Cherry Orchard (February 2011), Joseph K (October 2011), Cyrano de Bergerac (May 2012), Macbeth (October 2012), London Assurance (May 2013) and Jerusalem (October 2013). Upcoming in May 2014 was a production of A Midsummer Night's Dream . Often girls from surrounding schools, such as St George's, Ascot, St Mary's School Ascot, Windsor Girls' School and Heathfield St Mary's School, are cast in female roles. Boys from the School are also responsible for the lighting, sound and stage management of all the productions, under the guidance of several professional full-time theatre staff.
Document 6: Velvet Donkey: Velvet Donkey is an album by Ivor Cutler, originally released in 1975 on Virgin Records. Cutler is joined on the record by Fred Frith who plays viola on several tracks, and by Phyllis King who reads six of her own poems and short stories and is also credited with designing the album cover.
Document 7: Normans: The Normans had a profound effect on Irish culture and history after their invasion at Bannow Bay in 1169. Initially the Normans maintained a distinct culture and ethnicity. Yet, with time, they came to be subsumed into Irish culture to the point that it has been said that they became "more Irish than the Irish themselves." The Normans settled mostly in an area in the east of Ireland, later known as the Pale, and also built many fine castles and settlements, including Trim Castle and Dublin Castle. Both cultures intermixed, borrowing from each other's language, culture and outlook. Norman descendants today can be recognised by their surnames. Names such as French, (De) Roche, Devereux, D'Arcy, Treacy and Lacy are particularly common in the southeast of Ireland, especially in the southern part of County Wexford where the first Norman settlements were established. Other Norman names such as Furlong predominate there. Another common Norman-Irish name was Morell (Murrell) derived from the French Norman name Morel. Other names beginning with Fitz (from the Norman for son) indicate Norman ancestry. These included Fitzgerald, FitzGibbons (Gibbons) dynasty, Fitzmaurice. Other families bearing such surnames as Barry (de Barra) and De Búrca (Burke) are also of Norman extraction.
Document 8: Ivor Cutler: In 2014 a new play, "The Beautiful Cosmos of Ivor Cutler", a co-production by Vanishing Point and National Theatre of Scotland, was performed.
Document 9: Normans: The Normans (Norman: Nourmands; French: Normands; Latin: Normanni) were the people who in the 10th and 11th centuries gave their name to Normandy, a region in France. They were descended from Norse ("Norman" comes from "Norseman") raiders and pirates from Denmark, Iceland and Norway who, under their leader Rollo, agreed to swear fealty to King Charles III of West Francia. Through generations of assimilation and mixing with the native Frankish and Roman-Gaulish populations, their descendants would gradually merge with the Carolingian-based cultures of West Francia. The distinct cultural and ethnic identity of the Normans emerged initially in the first half of the 10th century, and it continued to evolve over the succeeding centuries.
Document 10: Normans: In 1066, Duke William II of Normandy conquered England killing King Harold II at the Battle of Hastings. The invading Normans and their descendants replaced the Anglo-Saxons as the ruling class of England. The nobility of England were part of a single Normans culture and many had lands on both sides of the channel. Early Norman kings of England, as Dukes of Normandy, owed homage to the King of France for their land on the continent. They considered England to be their most important holding (it brought with it the title of King—an important status symbol).
Document 11: To Kill a Mockingbird: Sergel's play toured in the UK starting at West Yorkshire Playhouse in Leeds in 2006, and again in 2011 starting at the York Theatre Royal, both productions featuring Duncan Preston as Atticus Finch. The play also opened the 2013 season at Regent's Park Open Air Theatre in London where it played to full houses and starred Robert Sean Leonard as Atticus Finch, his first London appearance in 22 years. The production is returning to the venue to close the 2014 season, prior to a UK Tour.
Document 12: Still Game: In November 2014, a special sketch featuring Jack and Victor visiting the set of "River City" was made for Children in Need. The sketch also featured a cameo of a director played by Still Game director Michael Hines. On Hogmanay 2014, BBC Scotland showed a documentary celebrating the show titled "Still Game: The Story So Far". The programme featured interviews with the cast, celebrities who have appeared on the show and super fans, including a look at some favourite moments.
Document 13: Norman architecture: In England, Norman nobles and bishops had influence before the Norman Conquest of 1066, and Norman influences affected late Anglo - Saxon architecture. Edward the Confessor was brought up in Normandy, and in 1042 brought masons to work on Westminster Abbey, the first Romanesque building in England. In 1051 he brought in Norman knights who built ``motte ''castles as a defence against the Welsh. Following the invasion Normans rapidly constructed motte - and - bailey castles, and in a burst of building activity built churches and abbeys, as well as more elaborate fortifications including Norman stone keeps.
Document 14: Macbeth: The play has been translated and performed in various languages in different parts of the world, and Media Artists was the first to stage its Punjabi adaptation in India. The adaptation by Balram and the play directed by Samuel John have been universally acknowledged as a milestone in Punjabi theatre. The unique attempt involved trained theatre experts and the actors taken from a rural background in Punjab. Punjabi folk music imbued the play with the native ethos as the Scottish setting of Shakespeare's play was transposed into a Punjabi milieu.
Document 15: Alex Bevan: The release of the album Springboard got him some public recognition due to the local hit song Skinny Little Boy. In 1977 he performed on the air on Cleveland's WMMS Radio with a band called Alex Bevan and the Buzzard Band, featuring DJ Matt the Cat on guitar. He performed in the mid-1970s with an acoustic trio consisting of two guitars and electric bass, and opened for such acts as Seals and Crofts, The Michael Stanley Band, The Doobie Brothers and Hall & Oates. He soon added David Krauss from the band Tiny Alice to the group, supplying percussion and harmonica. They toured either under the name Grand River Band or Alex Bevan and Friends from 1979 until 1981, and produced the albums The Grand River Lullaby, Alex Bevan and Friends Live, and Simple Things Done Well. In the early 80's Bevan produced the direct - to - disk digital solo album Tales of the Low Tech Troubadour Vol. 1. He played in the band Alex Bevan & Cuttlefish from 1984 through 1986. In the late 80s to early 90s, he produced the albums Best Kept Secrets, Cuttlefish Live, and Watersongs.
