input question: From what song, did a Czech rock group take its name?  Answer the above question based on the context below:  In a 1991 interview, Zappa reported that he was a registered Democrat but added "that might not last long—I'm going to shred that". Describing his political views, Zappa categorized himself as a "practical conservative". He favored limited government and low taxes; he also stated that he approved of national defense, social security, and other federal programs, but only if recipients of such programs are willing and able to pay for them. He favored capitalism, entrepreneurship, and independent business, stating that musicians could make more from owning their own businesses than from collecting royalties. He opposed communism, stating, "A system that doesn't allow ownership ... has—to put it mildly—a fatal design flaw." He had always encouraged his fans to register to vote on album covers, and throughout 1988 he had registration booths at his concerts. He even considered running for president of the United States as an independent.Zappa was an atheist. He recalled his parents being "pretty religious" and trying to make him go to Catholic school despite his resentment. He felt disgust towards organized religion (Christianity in particular) because he believed that it promoted ignorance and anti-intellectualism. Some of his songs, concert performances, interviews and public debates in the 1980s criticized and derided Republicans and their policies, President Ronald Reagan, the Strategic Defense Initiative (SDI), televangelism, and the Christian Right, and warned that the United States government was in danger of becoming a "fascist theocracy".In early 1990, Zappa visited Czechoslovakia at the request of President Václav Havel. Havel designated him as Czechoslovakia's "Special Ambassador to the West on Trade, Culture and Tourism". Havel was a lifelong fan of Zappa, who had great influence in the avant-garde and underground scene in Central Europe in the 1970s and 1980s (a Czech rock group that was imprisoned in 1976 took its name from Zappa's 1968 song "Plastic People"). Under pressure from Secretary of State...???

What is the first name of the person that allowed Trent to use the studio when it was empty?  Answer the above question based on the context below:  In 1987, Trent Reznor played keyboard in a Cleveland, Ohio band called the Exotic Birds, then managed by John Malm Jr. Reznor and Malm became friends, and when Reznor left the Exotic Birds to work on music of his own, Malm informally became his manager. At the time, Reznor was employed as an assistant engineer and janitor at Right Track Studios,  in Cleveland; he asked studio owner Bart Koster for permission to record some demos of his own material for free during unused studio time. Koster agreed and allowed Reznor to use it whenever it was empty, commenting that it cost him "just a little wear on [his] tape heads". While completing the early recordings, Reznor was unable to find a band that could articulate the material as he desired. Instead, inspired by Prince, Reznor played all the instruments, except drums, himself. This role remains Reznor's on most of the band's studio recordings, though he has occasionally involved other musicians and assistants. Nine Inch Nails' debut was at the Phantasy Theater in Lakewood, Ohio on October 21, 1988 as part of the Pretty Hate Machine Tour Series. In 1988, after playing its first shows supporting Skinny Puppy, Reznor's ambition for Nine Inch Nails was to release one 12-inch single on a small European label. Several labels responded favorably to the demo material and Reznor signed with TVT Records. Nine selections from the Right Track demos recorded live in November 1988, collectively known as Purest Feeling, were later released in revised form on the band's first full-length studio release, Pretty Hate Machine (1989). The overall sound on Purest Feeling is lighter than that of Pretty Hate Machine; several songs contain more live drumming and guitar work throughout, as well as a heavier use of samples from films.Reznor coined the name "Nine Inch Nails" because it "abbreviated easily", rather than for "any literal meaning". Other rumored explanations have circulated, alleging that Reznor chose to reference Jesus' crucifixion with nine-inch spikes, or Freddy Krueger's...

Problem: Given the question: What is the first name of the person who produced albums that included John Lennon/Plastic Ono Band and Imagine?  Answer the above question based on the context below:  John Winston Ono Lennon  (9 October 1940 – 8 December 1980) was an English singer, songwriter and peace activist who co-founded the Beatles, the most commercially successful band in the history of popular music. He and fellow member Paul McCartney formed a much-celebrated songwriting partnership. Along with George Harrison and Ringo Starr, the group achieved worldwide fame during the 1960s. In 1969, Lennon started the Plastic Ono Band with his second wife, Yoko Ono, and he continued to pursue a solo career following the Beatles' break-up in April 1970. Born  John Winston Lennon in Liverpool, he became involved in the skiffle craze as a teenager. In 1957, he formed his first band, the Quarrymen, which evolved into the Beatles in 1960. Further to his Plastic Ono Band singles such as "Give Peace a Chance" and "Instant Karma!", Lennon subsequently produced albums that included John Lennon/Plastic Ono Band and Imagine, and songs such as  "Working Class Hero", "Imagine" and "Happy Xmas (War Is Over)". After moving to New York City in 1971, he never returned to England again. In 1975, he disengaged himself from the music business to raise his infant son Sean, but re-emerged with Ono in 1980 with the album Double Fantasy. He was shot and killed in the archway of his Manhattan apartment building three weeks after the album's release. Lennon revealed a rebellious nature and acerbic wit in his music, writing, drawings, on film and in interviews. He was controversial through his political and peace activism. From 1971 onwards, his criticism of the Vietnam War resulted in a three-year attempt by the Nixon administration to deport him. Some of his songs were adopted as anthems by the anti-war movement and the larger counterculture. By 2012, Lennon's solo album sales in the United States had exceeded 14 million units. He had 25 number-one singles on the US Billboard Hot 100 chart as a writer, co-writer or performer. In 2002, Lennon was voted eighth in a BBC poll of the 100 Greatest Britons and in 2008, Rolling Stone ranked...
