Problem: Given the question: The answer to the question: What is the name of the band Harrison sought to alleviate tensions within, while improving their live sound, by inviting keyboardist Billy Preston to participate in the last nine days of sessions? is inside the article: Although Let It Be was the Beatles' final album release, it was largely recorded before Abbey Road. The project's impetus came from an idea Martin attributes to McCartney, who suggested they "record an album of new material and rehearse it, then perform it before a live audience for the very first time – on record and on film". Originally intended for a one-hour television programme to be called Beatles at Work, in the event much of the album's content came from studio work beginning in January 1969, many hours of which were captured on film by director Michael Lindsay-Hogg. Martin has said that the project was "not at all a happy recording experience. It was a time when relations between the Beatles were at their lowest ebb." Lennon described the largely impromptu sessions as "hell ... the most miserable ... on Earth", and Harrison, "the low of all-time". Irritated by both McCartney and Lennon, Harrison walked out for five days. Upon returning, he threatened to leave the band unless they "abandon[ed] all talk of live performance" and instead focused on finishing a new album, initially titled Get Back, using songs recorded for the TV special. He also demanded they cease work at Twickenham Film Studios, where the sessions had begun, and relocate to the newly finished Apple Studio. The other band members agreed, and the idea came about to salvage the footage shot for the TV production for use in a feature film. In an effort to alleviate tensions within the band and improve the quality of their live sound, Harrison invited keyboardist Billy Preston to participate in the last nine days of sessions. Preston received label billing on the "Get Back" single – the only musician ever to receive that acknowledgment on an official Beatles release. At the conclusion of the rehearsals, the band could not agree on a location to film a concert, rejecting several ideas, including a boat at sea, a lunatic asylum, the Tunisian desert, and the Colosseum. Ultimately, what would be their final live performance was filmed on the..., can you guess it ?

Problem: Given the question: The answer to the question: What is the name of the composer whose First Symphony was conducted by Bruno Walter at its Berlin premiere? is inside the article: After graduation, Shostakovich initially embarked on a dual career as concert pianist and composer, but his dry style of playing was often unappreciated (his American biographer, Laurel Fay, comments on his "emotional restraint" and "riveting rhythmic drive"). He nevertheless won an "honorable mention" at the First International Chopin Piano Competition in Warsaw in 1927. He attributed the disappointment at the competition to suffering from appendicitis and the jury being all-Polish. He had his appendix removed in April 1927. After the competition Shostakovich met the conductor Bruno Walter, who was so impressed by the composer's First Symphony that he conducted it at its Berlin premiere later that year. Leopold Stokowski was equally impressed and gave the work its U.S. premiere the following year in Philadelphia and also made the work's first recording. Shostakovich concentrated on composition thereafter and soon limited his performances primarily to those of his own works. In 1927 he wrote his Second Symphony (subtitled To October), a patriotic piece with a great pro-Soviet choral finale. Owing to its experimental nature, as with the subsequent Third Symphony, it was not critically acclaimed with the enthusiasm given to the First. 1927 also marked the beginning of Shostakovich's relationship with Ivan Sollertinsky, who remained his closest friend until the latter's death in 1944. Sollertinsky introduced the composer to the music of Mahler, which had a strong influence on his music from the Fourth Symphony onwards. While writing the Second Symphony, Shostakovich also began work on his satirical opera The Nose, based on the story by Nikolai Gogol. In June 1929, against the composer's own wishes, the opera was given a concert performance; it was ferociously attacked by the Russian Association of Proletarian Musicians (RAPM). Its stage premiere on 18 January 1930 opened to generally poor reviews and widespread incomprehension among musicians.In the late 1920s and early 1930s, Shostakovich worked at TRAM, a..., can you guess it ?
