[Q]: Passage: Slint formed in 1987 in Louisville, Kentucky, from the remnants of the punk rock band Squirrel Bait; the founding members included Brian McMahan (guitar, vocals), David Pajo (guitar), Britt Walford (drums) and Ethan Buckler (bass guitar). The band's debut album, the Steve Albini-produced Tweez, was released on the group's self-owned label Jennifer Hartman Records and Tapes. The album's sound has been described as a combination of "scratchy guitars, thumping bass lines and hard hitting drums". Buckler promptly left the band out of dissatisfaction with Albini's production, and was replaced with Todd Brashear. The band's second recording was for the instrumental extended play Slint, which included a new version of "Rhoda" from Tweez. The EP, which would not be released until 1994, was a departure from Tweez's sound and reflected the band's new musical direction.After the band ended its brief tour in support of Tweez, most of its members attended college. Around this time McMahan and Walford began writing together for the band's next record, creating six new songs which the band practiced throughout the summer of 1990. Slint entered River North Records in August 1990 to record Spiderland. At that time there were no vocals or lyrics prepared for the album, so the band wrote them while in the studio. The album's producer, Brian Paulson, was known for his "live" recording style in the studio, with minimal takes. Paulson recalled "It was weird while I was doing [Spiderland] because I remember sitting there, and I just knew there was something about it. I've never heard anything like this. I'm really digging this but it's really fucking weird."The recording sessions for Spiderland are reputed to have been difficult for the members of the band and were, according to AllMusic, "intense, traumatic and one more piece of evidence supporting the theory that band members had to be periodically institutionalized during the completion of the album." Rumors circulated that at least one member of Slint had been checked into a psychiatric hospital. Walford later addressed these stories in an article in Select by saying, "[We were] definitely trying to be serious about things, pretty intense, which made recording the album kinda stressful." The recording was completed in four days.
Question: What is the full name of the person that Todd Brashear replaced?
[A]: Ethan Buckler.

[Q]: Passage: Handel joined the Hamburg opera house when it was experiencing a period of considerable artistic success. This blossoming followed the arrival of Reinhard Keiser, who had become musical director at the Gansemarkt in about 1697, and in 1703 succeeded Johann Kusser as the theatre's manager. Born in 1674, Keiser had studied under Johann Schelle and probably Johann Kuhnau at the Thomasschule zu Leipzig. In 1694 he was employed as a court composer at Brunswick, where in three years he composed seven operas, at least one of which (Mahumeth) was performed in Hamburg. According to Handel's biographer Donald Burrows, Keiser was a good judge of popular taste, with a flair for writing Italian-style arias. Between 1697 and 1703, prior to Handel's arrival, about a dozen more Keiser operas had been staged at the Gansemarkt. Despite his on-stage successes, Keiser was an unreliable general manager, with expensive private tastes and little financial acumen, often at odds with his creditors.It is possible that Keiser, who had connections in the Halle area, had heard of Handel and was directly instrumental in securing the latter's post in the Gansemarkt orchestra; certainly he was a considerable influence on the younger man in the three years that Handel spent in Hamburg. Another important Gansemarkt colleague was the house composer and singer Johann Mattheson, who noted Handel's rapid progress in the orchestra from back-desk violinist to harpsichord soloist, a role in which, said Mattheson, "he showed himself a mana thing which no one had before suspected, save I alone". Mattheson was less complimentary on Handel's early efforts at composition: "He composed very long, long arias, and really interminable cantatas", before, it seems, "the lofty schooling of opera ... trimmed him into other fashions".
Question: What is the last name of the person who was employed as a court composer at Brunswick in 1694?
[A]: Keiser.

[Q]: Passage: Ravel was not by inclination a teacher, but he gave lessons to a few young musicians he felt could benefit from them. Manuel Rosenthal was one, and records that Ravel was a very demanding teacher when he thought his pupil had talent. Like his own teacher, Faure, he was concerned that his pupils should find their own individual voices and not be excessively influenced by established masters. He warned Rosenthal that it was impossible to learn from studying Debussy's music: "Only Debussy could have written it and made it sound like only Debussy can sound." When George Gershwin asked him for lessons in the 1920s, Ravel, after serious consideration, refused, on the grounds that they "would probably cause him to write bad Ravel and lose his great gift of melody and spontaneity". The best known composer who studied with Ravel was probably Ralph Vaughan Williams, who was his pupil for three months in 190708. Vaughan Williams recalled that Ravel helped him escape from "the heavy contrapuntal Teutonic manner ... Complexe mais pas complique was his motto."Vaughan Williams's recollections throw some light on Ravel's private life, about which the latter's reserved and secretive personality has led to much speculation. Vaughan Williams, Rosenthal and Marguerite Long have all recorded that Ravel frequented brothels. Long attributed this to his self-consciousness about his diminutive stature, and consequent lack of confidence with women. By other accounts, none of them first-hand, Ravel was in love with Misia Edwards, or wanted to marry the violinist Helene Jourdan-Morhange. Rosenthal records and discounts contemporary speculation that Ravel, a lifelong bachelor, may have been homosexual. Such speculation recurred in a 2000 life of Ravel by Benjamin Ivry; subsequent studies have concluded that Ravel's sexuality and personal life remain a mystery.Ravel's first concert outside France was in 1909. As the guest of the Vaughan Williamses, he visited London, where he played for the Societe des Concerts Francais, gaining favourable reviews and enhancing his growing international reputation.
Question: What is the last name man that speculated about the mysterious personal life and sexuality of the musician that gave lessons to Maneul Rosenthal?
[A]:
Ivry.
