Input: Consider Input: Passage: As far as we know, the earliest cantatas of Johann Sebastian Bach were performed in Mühlhausen from 1706 to 1708. He was employed as an organist there, but he occasionally composed cantatas, mostly for special occasions. The cantatas were based mainly on biblical texts and hymns, such as Aus der Tiefen rufe ich, Herr, zu dir, BWV 131 (a psalm setting), and the Easter chorale cantata Christ lag in Todes Banden, BWV 4.
Bach was next appointed organist and chamber musician in Weimar on 25 June 1708 at the court of the co-reigning dukes in Saxe-Weimar, Wilhelm Ernst and his nephew Ernst August. He initially concentrated on the organ, composing major works for the instrument, including the Orgelbüchlein, the Toccata and Fugue in D minor, BWV 565, and the Prelude and Fugue in E major, BWV 566. He was promoted to Konzertmeister on 2 March 1714, an honour that entailed performing a church cantata monthly in the Schlosskirche. The first cantatas he composed in the new position were Himmelskönig, sei willkommen, BWV 182, for Palm Sunday, Weinen, Klagen, Sorgen, Zagen, BWV 12 for Jubilate Sunday, and Erschallet, ihr Lieder, BWV 172, for Pentecost. Mostly inspired by texts by the court poet, Salomo Franck, they contain recitatives and arias. When Johann Samuel Drese, the Kapellmeister (director of music), died in 1716, Bach hoped in vain to become his successor. Bach looked for a better position and found it as Kapellmeister at the court of Leopold, Prince of Anhalt-Köthen. However, the duke in Weimar did not dismiss him and arrested him for disobedience. He was released on 2 December 1717.In Köthen, Bach found an employer who was an enthusiastic musician himself. The court was Calvinist, therefore Bach's work from this period was mostly secular, including the orchestral suites, the cello suites, the sonatas and partitas for solo violin, and the Brandenburg Concertos. He composed secular cantatas for the court for occasions such as New Year's Day and the prince's birthday, including Die Zeit, die Tag und Jahre macht, BWV 134a. He later parodied some of them as church cantatas without major changes, for example Ein Herz, das seinen Jesum lebend weiß, BWV 134. 
Question: What is full the name of the person whose successor Bach hoped in vain to become?

Output: Johann Samuel Drese.


Input: Consider Input: Passage: Boult was born in Chester, Cheshire, in North West England, the second child and only son of Cedric Randal Boult (1853–1950), and his wife Katharine Florence née Barman (d. 1927). Cedric Boult was a Justice of the Peace and a successful businessman connected with Liverpool shipping and the oil trade; Cedric and his family had "a Liberal Unitarian outlook on public affairs" with a history of philanthropy. When Boult was two years old the family moved to Blundellsands, where he was given a musical upbringing. From an early age he attended concerts in Liverpool, conducted mostly by Hans Richter. He was educated at Westminster School in London, where in his free time he attended concerts conducted by, among others, Sir Henry Wood, Claude Debussy, Arthur Nikisch, Fritz Steinbach, and Richard Strauss. His biographer, Michael Kennedy, writes, "Few schoolboys can have attended as many performances by great artists as Boult heard between 1901 and October 1908, when he went up to Christ Church, Oxford." While still a schoolboy, Boult met the composer Edward Elgar through Frank Schuster, a family friend.At Christ Church college at Oxford, where he was an undergraduate from 1908 to 1912, Boult studied history but later switched to music, in which his mentor was the musical academic and conductor Hugh Allen. Among the musical friends he made at Oxford was Ralph Vaughan Williams, who became a lifelong friend. In 1909 Boult presented a paper to an Oxford musical group, the Oriana Society, entitled Some Notes on Performance, in which he laid down three precepts for an ideal performance: observance of the composer's wishes, clarity through emphasis on balance and structure, and the effect of music made without apparent effort. These guiding principles lasted throughout his career. He was president of the University Musical Club for the year 1910, but his interests were not wholly confined to music: he was a keen rower, stroking his college boat at Henley, and all his life he remained a member of the Leander Club. 
Question: What is the last name of the person whose mentor was the musical academic and conductor Hugh Allen?

Output: Boult.


Input: Consider Input: Passage: Reign in Blood is regarded by critics as one of the most influential and extreme thrash metal albums. In its "Greatest Metal Bands Of All Time" poll, MTV praised Slayer's "downtuned rhythms, infectious guitar licks, graphically violent lyrics and grisly artwork," which they stated "set the standard for dozens of emerging thrash bands," while "Slayer's music was directly responsible for the rise of death metal." MTV described Reign in Blood as essential listening, and the album was ranked number 7 on IGN's "Top 25 Most Influential Metal Albums".
Asked during a press tour for 1994's Divine Intervention about the pressure of living up to Reign in Blood, King replied that the band did not try to better it, but just wanted to make music. In 2006, Blabbermouth's Don Kaye drew a comparison to the band's 2006 album Christ Illusion, and concluded, "Slayer may never make an album as incendiary as Reign in Blood again."Rapper Necro was heavily influenced by the album, and has remarked that it takes him back to the 1980s, "when shit was pure". Ektomorf vocalist Zoltán Farkas describes the album as one of his primary influences. Paul Mazurkiewicz of Cannibal Corpse stated Lombardo's performance on the album helped him play faster throughout his career.
Kelly Shaefer of Atheist said: "When Reign in Blood came out it changed everything! That is easily the best extreme metal record ever!"Hanneman said that the album was his personal favorite, reasoning it was "so short and quick and to the point". Araya has remarked that Slayer's 2006 album Christ Illusion "comes close", but that "nothing can surpass Reign in Blood for intensity and impact. No one had heard anything like it before. In the twenty years since then, people have got more desensitized. What was over the top then might not be now."Paul Bostaph – Slayer's drummer from 1992 to 2001, and 2013–present – first heard the record while a member of Forbidden. At a party, he walked towards music he heard from another room, and approached Forbidden guitarist Craig Locicero. Asked what was playing, Locicero shouted, "The new Slayer record." After listening closely, Bostaph looked at Locicero, and concluded his band was "fucked".Oderus Urungus of Gwar cited 'Altar of Sacrifice' as his favourite Slayer song: "It's the one I would always play for my friends when I was getting into Slayer. They would get this glazed look in their eyes and worship the speakers while doing the devil-horn thing."In 2006, the album won a Metal Hammer award for Best Album of the Last 20 Years.In 2016, Loudwire ranked Reign in Blood #1 among Slayer's eleven studio albums. 
Question: What is the last name of the person who walked towards music he heard from another room at a party?


Output: Bostaph.
