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

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