question:
Passage: Yorke said that the starting point for the record was the "incredibly dense and terrifying sound" of Bitches Brew, the 1970 avant-garde jazz fusion album by Miles Davis. He described the sound of Bitches Brew to Q: "It was building something up and watching it fall apart, that's the beauty of it. It was at the core of what we were trying to do with OK Computer." Yorke identified "I'll Wear It Proudly" by Elvis Costello, "Fall on Me" by R.E.M., "Dress" by PJ Harvey and "A Day in the Life" by the Beatles as particularly influential on his songwriting. Radiohead drew further inspiration from the recording style of film soundtrack composer Ennio Morricone and the krautrock band Can, musicians Yorke described as "abusing the recording process". Jonny Greenwood described OK Computer as a product of being "in love with all these brilliant records ... trying to recreate them, and missing."According to Yorke, Radiohead hoped to achieve an "atmosphere that's perhaps a bit shocking when you first hear it, but only as shocking as the atmosphere on the Beach Boys' Pet Sounds." They expanded their instrumentation to include electric piano, Mellotron, cello and other strings, glockenspiel and electronic effects. Jonny Greenwood summarised the exploratory approach as "when we've got what we suspect to be an amazing song, but nobody knows what they're gonna play on it." Spin characterised OK Computer as sounding like "a DIY electronica album made with guitars".Critics suggested a stylistic debt to 1970s progressive rock, an influence that Radiohead have disavowed. According to Andy Greene in Rolling Stone, Radiohead "were collectively hostile to seventies progressive rock ... but that didn't stop them from reinventing prog from scratch on OK Computer, particularly on the six-and-a-half-minute 'Paranoid Android'." Writing in 2017, The New Yorker's Kelefa Sanneh said OK Computer "was profoundly prog: grand and dystopian, with a lead single that was more than six minutes long.". 
Question: What band was Yorke a member of?
answer:
Radiohead.

Passage: With the piece set to open on 26 December, Gilbert first read the libretto to the cast on 14 December, but Toole, who was playing the central role of Thespis, did not return from a tour of the British provinces until 18 December. He then appeared in nine performances at the Gaiety in the six days immediately after his return, and other actors had similar commitments. In addition, Hollingshead had committed the company to perform a pantomime at The Crystal Palace on 21 December, which included many of the performers who would be in Thespis. Lastly, Thespis was to play as the afterpiece to an H. J. Byron comedy, Dearer than Life, which shared many of its actors, including Toole and Fred Sullivan, and had to be rehearsed at the same time.Despite the short time available for rehearsals, Sullivan recalled that Gilbert insisted that the chorus play a major role, as it would do in their later Savoy operas:
Until Gilbert took the matter in hand choruses were dummy concerns, and were practically nothing more than a part of the stage setting. It was in 'Thespis' that Gilbert began to carry out his expressed determination to get the chorus to play its proper part in the performance. At this moment it seems difficult to realise that the idea of the chorus being anything more than a sort of stage audience was, at that time, a tremendous novelty. In consequence of this innovation, some of the incidents at the rehearsal of 'Thespis' were rather amusing. I remember that, on one occasion, one of the principals became quite indignant and said, 'Really, Mr. Gilbert, why should I stand here? I am not a chorus-girl!' to which Gilbert replied curtly, 'No, madam, your voice is not strong enough, or no doubt you would be.'. 
Question: What is the last name of the person who had an expressed determination to get the chorus to play its proper part in the performance?
answer:
Gilbert.

Passage: In February 2011, Gaga released "Born This Way", the lead single from her studio album of the same name. The song sold more than one million copies within five days, earning the Guinness World Record for the fastest selling single on iTunes. It debuted atop the Billboard Hot 100, becoming the 1,000th number-one single in the history of the charts. Its second single "Judas" followed two months later, and "The Edge of Glory" served as its third single. Both reached the top 10 in the US and the UK. Her music video for "The Edge of Glory", unlike her previous work, portrays her dancing on a fire escape and walking on a lonely street, without intricate choreography and back-up dancers.
Gaga hosted an episode of Saturday Night Live in November 2013, performing "Do What U Want" (with Kelly) and an album cut, "Gypsy". After holding her second Thanksgiving Day television special on ABC, Lady Gaga and the Muppets Holiday Spectacular, she performed a special rendition of "Do What U Want" with Christina Aguilera on the fifth season of the American reality talent show The Voice. In March 2014, Gaga had a seven-day concert residency commemorating the last performance at New York's Roseland Ballroom before its closure. Two months later, she embarked on the ArtRave: The Artpop Ball tour, building on concepts from her ArtRave promotional event. Earning $83 million, the tour included cities canceled from the Born This Way Ball tour itinerary. In the meantime, Gaga split from longtime manager Troy Carter over "creative differences", and by June 2014, she and new manager Bobby Campbell joined Artist Nation, the artist management division of Live Nation Entertainment. She briefly appeared in Rodriguez's Sin City: A Dame to Kill For, and was confirmed as Versace's spring-summer 2014 face with a campaign called "Lady Gaga For Versace".In September 2014, Gaga released a collaborative jazz album with Tony Bennett titled Cheek to Cheek. The inspiration behind the album came from her friendship with Bennett, and fascination with jazz music since her childhood. Before the album was released, it produced the singles "Anything Goes" and "I Can't Give You Anything but Love". Cheek to Cheek received generally favorable reviews; The Guardian's Caroline Sullivan praised Gaga's vocals and Howard Reich of the Chicago Tribune wrote that "Cheek to Cheek serves up the real thing, start to finish". The record was Gaga's third consecutive number-one album on the Billboard 200, and won a Grammy Award for Best Traditional Pop Vocal Album. The duo recorded the concert special Tony Bennett and Lady Gaga: Cheek to Cheek Live!, and embarked on the Cheek to Cheek Tour from December 2014 to August 2015. 
Question: What is the full name of the person that embarked on the ArtRave: The Artpop Ball tour?
answer:

Lady Gaga.
