Question: Beni Mora was created by which English composer and arranger?
Context: Neil Grant Richardson (5 February 1930 – 8 October 2010) was an English composer and conductor.  As a composer, he is perhaps best known for "Approaching Menace" (the "Mastermind" theme tune) and "The Riviera Affair".  During the 1960s–1990s, he was an arranger and conductor of various BBC Radio Orchestras, working on programmes such as "String Sound" and "The Radio Orchestra Show".  He was a prolific composer of library music for companies such as KPM, and his music has been used in numerous TV, film and radio productions. Nigel Brooks (born 1936) is an English composer, arranger and conductor.  He was born in Barnstaple and spent most of his childhood in Ilfracombe, North Devon.  He attended Guildhall School of Music and Drama in London.  For much of his career he was an orchestral arranger, particularly for the BBC and also conducted the BBC Concert Orchestra.  He formed his own musical ensemble "The Nigel Brooks Singers" which appeared on "Friday Night is Music Night" and earned three gold discs, and two silver. Gustav Theodore Holst (born Gustavus Theodore von Holst; 21 September 1874 – 25 May 1934) was an English composer, arranger and teacher.  Best known for his orchestral suite "The Planets", he composed a large number of other works across a range of genres, although none achieved comparable success.  His distinctive compositional style was the product of many influences, Richard Wagner and Richard Strauss being most crucial early in his development.  The subsequent inspiration of the English folksong revival of the early 20th century, and the example of such rising modern composers as Maurice Ravel, led Holst to develop and refine an individual style. Gordon Langford (11 May 1930 – 18 April 2017) was an English composer, arranger and performer.  He is well known for his brass band compositions and arrangements.  He was also a composer of choral and orchestral music, winning an Ivor Novello award for best light music composition for his "March from the Colour Suite" in 1971. Imogen Clare Holst CBE (12 April 1907 – 9 March 1984) was an English composer, arranger, conductor, teacher and festival administrator.  The only child of the composer Gustav Holst, she is particularly known for her educational work at Dartington Hall in the 1940s, and for her 20 years as joint artistic director of the Aldeburgh Festival.  In addition to composing music, she wrote composer biographies, much educational material, and several books on the life and works of her father. Sir Henry Rowley Bishop (18 November 178630 April 1855) was an English composer.  He is most famous for the songs "Home!  Sweet Home! " and "Lo!  Here the Gentle Lark."  He was the composer or arranger of some 120 dramatic works, including 80 operas, light operas, cantatas, and ballets.  Knighted in 1842, he was the first musician to be so honoured.  Bishop worked for all the major theatres of London in his era — including the Royal Opera House at Covent Garden, the Theatre Royal, Drury Lane, Vauxhall Gardens and the Haymarket Theatre, and was Professor of Music at the universities of Edinburgh and Oxford.  His second wife was the noted soprano Anna Bishop, who scandalised British society by leaving him and conducting an open liaison with the harpist Nicolas-Charles Bochsa until the latter's death in Sydney. Ernest Austin (31 December 1874 – 24 July 1947) was an English composer, music arranger and editor.  Although little-remembered today (he does not even have an entry in the comprehensive "New Grove" dictionary), Austin's orchestral music enjoyed some success in its own time, including performances at the Henry Wood Promenade Concerts and on BBC Radio during the 1920s.  He was a prolific composer of songs, covering a wide spectrum of mood, from serious Shakespearean settings to ballads of both sentimental and robust natures.  He found some success writing piano pieces and unison songs for children.  He also made piano transcriptions of the work of other composers, a particularly common practice of the time. Herbert J. Ellis (born in Dulwich, London, 4 July 1865, died 13 October 1903 in St. Thomas' Hospital, London) was a banjo player, a mandolinist, guitar player and a composer.  Music historian Philip J. Bone called him "without question the most fertile English composer and arranger for mandolin and guitar."  He was the author of a banjo method, a guitar method, and a "Tutor for Mandolin" (1892), which he wrote while still in school. Jane Marian Joseph (31 May 1894 – 9 March 1929) was an English composer, arranger and music teacher.  She was a pupil and later associate of the composer Gustav Holst, and was closely concerned in the organisation and management of various of the music festivals which Holst sponsored.  Many of her works were composed for performance at these festivals and similar occasions.  Her early death, which prevented the full realisation of her talents, was considered by her contemporaries as a considerable loss to English music. Beni Mora is a three-movement suite of music in E minor for large orchestra, by Gustav Holst.  The first performance was at the Queen's Hall, London, on 1 May 1912, conducted by the composer.  The work was inspired by music Holst heard in Algeria during a holiday in 1908.  The constant repetition of one theme from Arabic folk music in the last movement has been described as a precursor of modern minimalism.  The piece also includes dance rhythms and wistful, slow sections, and makes strong use of woodwinds and percussion.  "Beni Mora" has been recorded several times by British orchestras, most recently in 2011.
