Question: Passage: In 1952 the LPO negotiated a five-year contract with Decca Records, which was unusually rewarding for the orchestra, giving it a 10 per cent commission on most sales. On top of this, Boult always contributed his share of the recording fees to the orchestra's funds. In the same year, the LPO survived a crisis when Russell was dismissed as its managing director. He was an avowed member of the Communist party; when the cold war began some influential members of the LPO felt that Russell's private political affiliations compromised the orchestra, and pressed for his dismissal. Boult, as the orchestra's chief conductor, stood up for Russell, but when matters came to a head Boult ceased to protect him. Deprived of that crucial support, Russell was forced out. Kennedy speculates that Boult's change of mind was due to a growing conviction that the orchestra would be "seriously jeopardized financially" if Russell remained in post.  A later writer, Richard Witts, suggests that Boult sacrificed Russell because he believed doing so would enhance the LPO's chance of being appointed resident orchestra at the Royal Festival Hall.In 1953 Boult once again took charge of the orchestral music at a coronation, conducting an ensemble drawn from UK orchestras at the coronation of Elizabeth II. During the proceedings, he conducted the first performances of Bliss's Processional and Walton's march Orb and Sceptre.  In the same year he returned to the Proms after a three-year absence, conducting the LPO. The notices were mixed: The Times found a Brahms symphony "rather colourless, imprecise and uninspiring", but praised Boult and the orchestra's performance of The Planets. In the same year the orchestra celebrated its 21st birthday, giving a series of concerts at the Festival Hall and the Royal Albert Hall in which Boult was joined by guest conductors including Paul Kletzki, Jean Martinon,  Hans Schmidt-Isserstedt, Georg Solti, Walter Susskind and Vaughan Williams.In 1956 Boult and the LPO visited Russia. Boult had not wished to go on the tour because flying hurt his ears, and long land journeys hurt his back. The Soviet authorities threatened to cancel the tour if he did not lead it, and he felt obliged to go. The LPO gave nine concerts in Moscow and four in Leningrad.  Boult's assistant conductors were Anatole Fistoulari and George Hurst. Boult's four Moscow programmes included Vaughan Williams's Fourth and Fifth Symphonies, Holst's The Planets, Walton's Violin Concerto (with Alfredo Campoli as soloist), and Schubert's Great C major Symphony. While in Moscow, Boult and his wife visited the Bolshoi Opera and were guests at the composer Dmitri Shostakovich's 50th birthday party.After the Russian tour, Boult told the LPO that he wished to step down from the principal conductorship. He continued to be the orchestra's main conductor until his successor William Steinberg took up the post in 1959.  After the sudden resignation of Andrzej Panufnik from the City of Birmingham Symphony Orchestra (CBSO), Boult returned as principal conductor of the CBSO for the 1959–60 season. That was his last chief conductorship, though he remained closely associated with the LPO as its president and a guest conductor until his retirement. 
Question: What is the name of the person that flying hurt his ears, and long land journeys hurt his back?

Answer: Boult.


Question: Passage: Ferrier gave her first London recital on 28 December 1942 at the National Gallery, in a lunch-time concert organised by Dame Myra Hess. Although she wrote "went off very well" in her diary, Ferrier was disappointed with her performance, and concluded that she needed further voice training. She approached the distinguished baritone Roy Henderson with whom, a week previously, she had sung in Mendelssohn's Elijah. Henderson agreed to teach her, and was her regular voice coach for the remainder of her life. He later explained that her "warm and spacious tone" was in part due to the size of the cavity at the back of her throat: "one could have shot a fair-sized apple right to the back of the throat without obstruction". However, this natural physical advantage was not in itself enough to ensure the quality of her voice; this was due, Henderson says, to "her hard work, artistry, sincerity, personality and above all her character".
Ferrier's performances in the Glyndebourne run, which began on 12 July 1946, earned her favourable reviews, although the opera itself was less well received. On the provincial tour which followed the festival it failed to attract the public and incurred heavy financial losses.
By contrast, when the opera reached Amsterdam it was greeted warmly by the Dutch audiences who showed particular enthusiasm for Ferrier's performance. This was Ferrier's first trip abroad, and she wrote an excited letter to her family: "The cleanest houses and windows you ever did see, and flowers in the fields all the way!" Following her success as Lucretia she agreed to return to Glyndebourne in 1947, to sing Orfeo in Gluck's opera Orfeo ed Euridice. She had often sung Orfeo's aria Che farò ("What is life") as a concert piece, and had recently recorded it with Decca. At Glyndebourne, Ferrier's limited acting abilities caused some difficulties in her relationship with the conductor, Fritz Stiedry; nevertheless her performance on the first night, 19 June 1947, attracted warm critical praise.Ferrier's association with Glyndebourne bore further fruit when Rudolf Bing, the festival's general manager, recommended her to Bruno Walter as the contralto soloist in a performance of Mahler's symphonic song cycle Das Lied von der Erde. This was planned for the 1947 Edinburgh International Festival. Walter was initially wary of working with a relatively new singer, but after her audition his fears were allayed; "I recognised with delight that here potentially was one of the greatest singers of our time", he later wrote. Das Lied von der Erde was at that time largely unknown in Britain, and some critics found it unappealing; nevertheless, the Edinburgh Evening News thought it "simply superb". In a later biographical sketch of Ferrier, Lord Harewood described the partnership between Walter and her, which endured until the singer's final illness, as "a rare match of music, voice and temperament.". 
Question: What is the last name of the person who sang with Roy in Mendelssohn's Elijah?

Answer: Ferrier.


Question: Passage: Many independent Chicago-based record labels were also getting their artists on the dance charts. Detroit DJ Terrence Parker uses his advanced turntablism skills and his focus on precision to blend hip hop music DJing styles, such as rhythmic scratching, in his house mixes. Fellow Detroit spinner DJ Minx is a notable woman house DJ. Her records on her Women on Wax label blend Parker-influenced turntablism precision with a funky style.
In the UK, any house song released by a Chicago-based label was routinely considered a "must-play" at UK house music clubs. Paradise Garage in New York City was still a top club in the house era, just as it had been during the disco age. The emergence of Todd Terry, a pioneer of the genre, demonstrated the continuum from the underground disco approach which moved to a new house sound. Terry's cover of Class Action's "Weekend" (mixed by Larry Levan) shows how Terry drew on newer hip-hop influences, such as the quicker sampling and the more rugged basslines.
In the late 1980s, Nu Groove Records launched and nurtured the careers of Rheji Burrell and Rhano Burrell, collectively known as Burrell (after a brief stay on Virgin America via Timmy Regisford and Frank Mendez). Nu Groove also had a stable of other NYC underground scene DJs. The Burrell's created the "New York Underground" sound of house, and they did 30+ releases on this label featuring this sound. In the 2010s, Nu Groove Record releases like the Burrells' enjoy a cult status among "crate diggers" and DJs. Mint-condition vinyl records by the Burrells from the 1980s can fetch high prices.
By the late 1980s, house DJing and production had moved to the US's west coast, particularly to San Francisco, Oakland, Los Angeles, Fresno, San Diego and Seattle. Los Angeles saw am explosion of underground raves, where DJs mixed dance tracks. L.A. DJs Marques Wyatt and Billy Long spun at Jewel's Catch One. In 1989, the L.A.-based, former EBN-OZN singer/rapper Robert Ozn started indie house label One Voice Records. Ozn released the Mike "Hitman" Wilson remix of Dada Nada's "Haunted House", which garnered club and mix show radio play in Chicago, Detroit and New York as well as in the U.K. and France. The record went up to number five on the Billboard Club Chart, marking it as the first house record by a white (Caucasian) artist to chart in the U.S.  Dada Nada, the moniker for Ozn's solo act, did his first releases in 1990, using a jazz-based Deep House style. The Frankie Knuckles and David Morales remix of Dada Nada's "Deep Love" (One Voice Records in the US, Polydor in the UK), featuring Ozn's lush, crooning vocals and jazzy improvisational solos by muted trumpet, underscored Deep House's progression into a genre that integrated jazz and pop songwriting and song forms (unlike acid house and techno). 
Question: What is the first name of the person whose alias is Dada Nada?

Answer:
Robert.
