input: In 1975, Pink Floyd bought a three-storey group of church halls at 35 Britannia Row in Islington and began converting the building into a recording studio and storage space. In 1976, they recorded their tenth album, Animals, in their newly finished 24-track studio. The concept of Animals originated with Waters, loosely based on George Orwell's political fable, Animal Farm. The album's lyrics described different classes of society as dogs, pigs, and sheep. Hipgnosis received credit for the packaging of Animals; however, Waters designed the final concept, choosing an image of the ageing Battersea Power Station, over which they superimposed an image of a pig.  The division of royalties was a source of conflict between band members, who earned royalties on a per-song basis. Although Gilmour was largely responsible for "Dogs", which took up almost the entire first side of the album, he received less than Waters, who contributed the much shorter two-part "Pigs on the Wing". Wright commented: "It was partly my fault because I didn't push my material ... but Dave did have something to offer, and only managed to get a couple of things on there." Mason recalled: "Roger was in full flow with the ideas, but he was really keeping Dave down, and frustrating him deliberately." Gilmour, distracted by the birth of his first child, contributed little else toward the album. Similarly, neither Mason nor Wright contributed much toward Animals; Wright had marital problems, and his relationship with Waters was also suffering. Animals is the first Pink Floyd album that does not include a writing credit for Wright, who commented: "Animals... wasn't a fun record to make ... this was when Roger really started to believe that he was the sole writer for the band ... that it was only because of him that [we] were still going ... when he started to develop his ego trips, the person he would have his conflicts with would be me."  Released in January 1977, the album peaked on the UK chart at number two, and the US chart at number three. NME described the album as "one of the most extreme, relentless, harrowing and downright iconoclastic hunks of music", and Melody Maker's Karl Dallas called it "[an] uncomfortable taste of reality in a medium that has become in recent years, increasingly soporific".  Pink Floyd performed much of the album's material during their "In the Flesh" tour. It was the band's first experience playing large stadiums, whose size caused unease in the band. Waters began arriving at each venue alone, departing immediately after the performance. On one occasion, Wright flew back to England, threatening to leave the band. At the Montreal Olympic Stadium, a group of noisy and enthusiastic fans in the front row of the audience irritated Waters so much that he spat at one of them. The end of the tour marked a low point for Gilmour, who felt that the band achieved the success they had sought, with nothing left for them to accomplish.

Answer this question "Were there any problems with the band during the making of the album?"
output: Mason recalled: "Roger was in full flow with the ideas, but he was really keeping Dave down, and frustrating him deliberately."

Question: Sven Anders Hedin, KNO1kl RVO, (19 February 1865 - 26 November 1952) was a Swedish geographer, topographer, explorer, photographer, travel writer, and illustrator of his own works. During four expeditions to Central Asia, he made the Transhimalaya known in the West and located sources of the Brahmaputra, Indus and Sutlej Rivers. He also mapped lake Lop Nur, and the remains of cities, grave sites and the Great Wall of China in the deserts of the Tarim Basin. In his book Fran pol till pol (From Pole to Pole), Hedin describes a journey through Asia and Europe between the late 1880s and the early 1900s.

Hedin's conservative and pro-German views eventually translated into sympathy for the Third Reich, and this would draw him into increasing controversy towards the end of his life. Adolf Hitler had been an early admirer of Hedin, who was in turn impressed with Hitler's nationalism. He saw the German leader's rise to power as a revival of German fortunes, and welcomed its challenge against Soviet Communism. He was not an entirely uncritical supporter of the Nazis, however. His own views were shaped by traditionalist, Christian and conservative values, while National Socialism was in part a modern revolutionary-populist movement. Hedin objected to some aspects of National Socialist rule, and occasionally attempted to convince the German government to relent in its anti-religious and anti-Semitic campaigns.  Hedin met Adolf Hitler and other leading National Socialists repeatedly and was in regular correspondence with them. The politely-worded correspondence usually concerned scheduling matters, birthday congratulations, Hedin's planned or completed publications, and requests by Hedin for pardons for people condemned to death, and for mercy, release and permission to leave the country for people interned in prisons or concentration camps. In correspondence with Joseph Goebbels and Hans Drager, Hedin was able to achieve the printing of the Daily Watchwords year after year.  The Nazis attempted to achieve a close connection to Hedin by bestowing awards upon him. They asked him to present an address on Sport as a Teacher at the 1936 Summer Olympics in Berlin's Olympic stadium. They made him an honorary member of the German-Swedish Union Berlin (German: Deutsch-Schwedischen Vereinigung Berlin e.V.) In 1938, they presented him with the City of Berlin's Badge of Honor (German: Ehrenplakette der Stadt Berlin). For his 75th birthday on 19 February 1940 they awarded him the Order of the German Eagle; shortly before that date it had been presented to Henry Ford and Charles Lindbergh. On New Year's Day 1943 they released the Oslo professor of philology and university rector Didrik Arup Seip from the Sachsenhausen concentration camp at Hedin's request in order to obtain Hedin's agreement to accept additional honors during the 470th anniversary of Munich University. On 15 January 1943, he received the Gold Medal of the Bavarian Academy of Sciences (Goldmedaille der Bayerischen Akademie der Wissenschaften). On 16 January 1943 he received an honorary doctorate from the faculty of natural sciences of Munich University. On the same day, the Nazis founded in his absence the Sven Hedin Institute for Inner Asian Research located at Mittersill Castle, which was supposed to serve the long-term advancement of the scientific legacy of Hedin and Wilhelm Filchner as Asian experts. However, it was instead misused by Heinrich Himmler as an institute of the Research Association for German Genealogical Inheritance (Forschungsgemeinschaft Deutsches Ahnenerbe e.V.). On 21 January 1943, he was requested to sign the Golden Book of the city of Munich.  Hedin supported the Nazis in his journalistic activities. After the collapse of Nazi Germany, he did not regret his collaboration with the Nazis because this cooperation had made it possible to rescue numerous Nazi victims from execution, or death in extermination camps.
