Question: Which band was formed in Edinburgh and had the genre influenced by the music of Appalachia?

Context paragraphs:
Brit funk: Brit funk is a musical style that has its origins in the British music scene of the late 1970s-1980s.  It mixes elements from jazz, funk, urban dance rhythms and pop hooks.  The scene originated in southern England and spread with support from DJs including Chris Hill and Colin Curtis.  Major acts included Light of the World, Level 42, Shakatak and Freeez.  The genre influenced 1980s pop groups such as Haircut 100, Wham and Spandau Ballet and started the trend for football style chanting in clubs.

Rising Appalachia: Rising Appalachia is an American musical group led by multi-instrumentalist sisters Leah and Chloe Smith.  Leah also performs as a solo artist under the name Leah Song.  Based between Southern Appalachia and New Orleans, the sisters work with an array of international musicians and the band incorporates everything from simple harmonics with banjos and fiddles, to a wide variety of drums, kalimbas, beatbox, djembe, baliphone, congas, didgeridoo, tablas, spoons and washboard creating a full mix of world, folk and soul music.

British hip hop: British hip hop is a genre of music, and a culture that covers a variety of styles of hip hop music made in Scotland, England, Wales and Northern Ireland (Great Britain).  It is generally classified as one of a number of styles of urban music.  British hip hop was originally influenced by the dub/toasting introduced to the United Kingdom by Jamaican migrants in the 1960s–70s, who eventually developed uniquely influenced rapping (or speed-toasting) in order to match the rhythm of the ever-increasing pace and aggression of Jamaican-influenced dub in the UK and to describe street/gang violence, similar to that in the US.  UK rap has also been heavily influenced by US hip-hop.  British hip hop, particularly that originating from London, was commercially superseded by grime, however, after a post-millennium boom period, the genre remains a hotbed of talent.

Swamptrash: Swamptrash were a Scottish bluegrass/psychobilly band formed in 1987 in Edinburgh.  They split in 1990 and several of the members went on to form Shooglenifty.  The band has been recognized as crucial to the development of experimental Scottish acoustic music.

Western music (North America): Western music is a form of country music composed by and about the people who settled and worked throughout the Western United States and Western Canada.  Directly related musically to old English, Scottish, and Irish folk ballads, Western music celebrates the life of the cowboy on the open ranges and prairies of Western North America.  The Mexican folk music of the American Southwest also influenced the development of this genre.  Western music shares similar roots with Appalachian music (also called "hillbilly music"), which developed in Appalachia separately from, but parallel to, the western music genre.  The music industry of the mid-20th century grouped the two genres together under the banner of "country and western music", later amalgamated into the modern name, "country music".

Bango (music): Bango is a music style created and made popular at the East African Coast by Joseph Ngala.  It fuses traditional Portuguese music genres, Arabic influenced taarab music, jazz and music genres of local coastal Bantu languages.  It resembles easy listening music styles of Latin america such as bossa nova and music styles of many Indian Ocean Islands such as Seychelles and Mauritius.  Joseph Ngala (also known by stage name ""Mzee Ngala"") is a renowned Kenyan Bango musician who comes from Freretown, Mombasa, and also the founder of the genre.  He performed in the past with famous groups such as the Hodi Boys and was also founder and band leader of the 60s and 70s group Bahari Boys.  In the band, he was their main composer and inspiration.  In fact, Mzee Ngala's song "Bango" is the originator of the name Bango.  The resilience of the name, Bango, is testament to the genre created by Mzee Ngala.

Music of Bahrain: The music of Bahrain is part of the Persian Gulf folk traditions.  Alongside Kuwait, it is known for sawt music, a bluesy genre influenced by African, Indian and Persian music.  Sultan Hamid, Ali Bahar and Khalid al Shaikh (a singer and oud player) are among the most popular musicians from Bahrain.

Bluegrass music: Bluegrass music is a form of American roots music, and a related genre of country music.  Influenced by the music of Appalachia, bluegrass has mixed roots in Irish, Scottish and English traditional music, and was also later influenced by the music of African-Americans through incorporation of jazz elements.

Chamber jazz: Chamber jazz is a genre of jazz involving small, acoustic-based ensembles where group interplay is important.  It is influenced aesthetically by musical neoclassicism and is often influenced by classical forms of Western music as well as non-Western music or culture.  That stated, in many cases the influence is traditional Celtic music, , or Latin American music instead.  The genre primarily began in Europe so significant neoclassical composers of Europe, like Igor Stravinsky, are important in it.  The German ECM Records also played a role in it beginning in the late 1960s.  It is also noted for using instruments not normally associated with jazz.  For example, chamber jazz will make use of the oboe, mandolin, cymbalum, or the tabla.

Andrew Gray (17th-century divine): Gray was born in a house still standing on the north side of the Lawnmarket, Edinburgh, in August 1633 (bap.  reg.  23).  He was fourth son and eleventh child in a family of twenty-one, his father being Sir William Gray of Pittendrum (died 1648), an eminent merchant and royalist, descended from Andrew, first lord Gray.  His mother was Geils or Egidia Smyth, sister to Sir John Smyth of Grothill, at one time provost of Edinburgh.  Andrew in his childhood was playful and fond of pleasure; but while he was quite young his thoughts were suddenly given a serious turn by reflecting on the piety of a beggar whom he met near Leith.  Resolved to enter the ministry, he studied at the universities both of St. Andrews and Edinburgh.  He graduated at the former in 1651.  Gray was one of that band of youthful preachers who were powerfully influenced by the venerable Leighton.  His talents and learning favourably impressed Principal Gillespie.  He was licensed to preach in 1653, and was ordained to the collegiate charge of the Outer High Church of Glasgow on 3 Nov. 1653, although only in his twenty-first year, notwithstanding some remonstrance.  One of the remonstrants, Robert Baillie, refers in his "Letters and Journals" to the ‘high flown, rhetorical style’ of the youthful preacher, and describes his ordination as taking place ‘over the belly of the town's protestation.’  His ministry proved eminently successful, and although only of three years' duration, in the profound impression produced during his lifetime, and the sustained popularity of his published works, Gray had few rivals in the Scottish church.  He died on 8 Feb. 1656, after a brief illness, of a ‘purple’ fever, and was interred in Blackadder's or St. Fergus's Aisle, Glasgow Cathedral.  On the walls of the aisle his initials and date of death may be seen deeply incised.  Gray married Rachael, daughter of Robert Baillie of Jerviswood, and had a son, William, born at Glasgow in March 1655, who probably died young.  He had also a daughter, Rachael, who was served heir to her father on 26 June 1669.  His widow remarried George Hutcheson, minister at Irvine.
