Some context: Ryuichi Sakamoto (Ban Ben  Long Yi , Sakamoto Ryuichi, born January 17, 1952) (Japanese pronunciation: [sakamoto rjW:itci]) is a Japanese musician, singer, composer, record producer, activist, writer, actor and dancer, based in Tokyo and New York. He began his career while at university in the 1970s, as a session musician, producer, and arranger.
Sakamoto's production credits represent a prolific career in this role. In 1983, he produced Mari Iijima's debut album Rose, the same year that the Yellow Magic Orchestra was disbanded. Sakamoto subsequently worked with artists such as Thomas Dolby; Aztec Camera, on the Dreamland (1993) album; and Imai Miki, co-producing her 1994 album A Place In The Sun.  Roddy Frame, who worked with Sakamoto as a member of Aztec Camera, explained in a 1993 interview preceding the release of Dreamland that he had had to wait a lengthy period of time before he was able to work with Sakamoto, who wrote two soundtracks, a solo album and the music for the opening ceremony at the Barcelona Olympics, prior to working with Frame over four weeks in a New York studio. Frame said that he was impressed by the work of YMO and the Merry Christmas Mr Lawrence soundtrack, explaining: "That's where you realise that the atmosphere around his compositions is actually in the writing - it's got nothing to do with synthesisers." Frame's decision to ask Sakamoto was finalized after he saw his performance at the Japan Festival that was held in London, United Kingdom. Of his experience recording with Sakamoto, Frame said:  He's got this reputation as a boffin, a professor of music who sits in front of a computer screen. But he's more intuitive than that, and he's always trying to corrupt what he knows. Halfway through the day in the studio, he will stop and play some hip hop or some house for 10 minutes, and then go back to what he was doing. He's always trying to trip himself up like that, and to discover new things. Just before we worked together he'd been out in Borneo, I think, with a DAT machine, looking for new sounds.
Where else does he look for new sounds?
A: machine, looking for new sounds.

Some context: Daniel Barenboim (born 15 November 1942) is an Argentine-Israeli pianist and conductor who is a citizen of Argentina, Israel, Palestine, and Spain. He is the general music director of the Berlin State Opera, and the Staatskapelle Berlin; he previously served as Music Director of the Chicago Symphony Orchestra, the Orchestre de Paris and La Scala in Milan. Barenboim is known for his work with the West-Eastern Divan Orchestra, a Seville-based orchestra of young Arab and Israeli musicians, and as a resolute critic of the Israeli occupation of Palestinian territories. Barenboim has received many awards and prizes, including an honorary Knight Commander of the Order of the British Empire, France's Legion d'honneur both as a Commander and Grand Officier, and the German Grosses Bundesverdienstkreuz and Willy Brandt Award.
In the beginning of his career, Barenboim concentrated on music of the classical era, as well as some romantic composers. He made his first recording in 1954. Notable classical recordings include the complete cycles of Mozart, Beethoven and Schubert's piano sonatas, and Mozart's piano concertos (in the latter, taking part as both soloist and conductor). Romantic recordings include Brahms's piano concertos (with John Barbirolli), Mendelssohn's Songs Without Words, and Chopin's nocturnes. Barenboim also recorded many chamber works, especially in collaboration with his first wife, Jacqueline du Pre, the violinist Itzhak Perlman, and the violinist and violist Pinchas Zukerman. Noted performances include: the complete Mozart violin sonatas (with Perlman), Brahms's violin sonatas (live concert with Perlman, previously in the studio with Zukerman), Beethoven's and Brahms's cello sonatas (with du Pre), Beethoven's and Tchaikovsky's piano trios (with du Pre and Zukerman), and Schubert's Trout Quintet (with du Pre, Perlman, Zukerman, and Zubin Mehta).  Notable recordings as a conductor include: the complete symphonies of Beethoven, Brahms, Bruckner, Schubert and Schumann, the Da Ponte operas of Mozart, numerous operas by Wagner, including the complete Ring Cycle, and various concertos. Barenboim has written about his changing attitude to the music of Mahler; he has recorded Mahler's Fifth, Seventh and Ninth symphonies and Das Lied von der Erde. He has also performed and recorded the Concierto de Aranjuez by Rodrigo and Villa-Lobos guitar concerto with John Williams as the guitar soloist.  By the late 1990s, Barenboim had widened his concert repertoire, performing works by baroque as well as twentieth-century classical composers. Examples include: J.S. Bach's The Well-Tempered Clavier (which he has played since childhood) and Goldberg Variations, Albeniz's Iberia, and Debussy's Preludes. In addition, he turned to other musical genres, such as jazz, and the folk music of his birthplace, Argentina. He conducted the 2006 New Year's Eve concert in Buenos Aires, in which tangos were played.  Barenboim has continued to perform and record chamber music, sometimes with members of the orchestras he has led. Some examples include the Quartet for the End of Time by Messiaen with members of the Orchestre de Paris during his tenure there, Richard Strauss with members of the Chicago Symphony Orchestra, and Mozart's Clarinet Trio with members of the Berlin Staatskapelle.  To mark Barenboim's 75th birthday, Deutsche Grammophon released a box set of 39 CDs of his solo recordings, and Sony Classical issued a box set of Barenboim's orchestral recordings on 43 CDs and three DVDs in 2017, Daniel Barenboim - A Retrospective.
