Question: 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.

Problem: James Lawrence Levine (; born June 23, 1943) is an American conductor and pianist. He is primarily known for his tenure as Music Director of the Metropolitan Opera (the "Met"), a position he held for 40 years (1976-2016). He was formally terminated by the Met from all his positions and affiliations with the company on March 12, 2018 over sexual misconduct allegations which he denies.

Levine made his Metropolitan Opera (the "Met") debut at age 28 on June 5, 1971, leading a June Festival performance of Tosca. Following further appearances with the company, he was named principal conductor of the Metropolitan Opera in February 1972. He became the Met's principal conductor in 1973, and its Music Director in 1975. In 1983, he served as conductor and musical director for the Franco Zeffirelli screen adaptation of La Traviata, which featured the Met orchestra and chorus members. He became the company's first artistic director in 1986, and relinquished the title in 2004. In 2005, Levine's combined salary from the Boston Symphony Orchestra and the Met made him the highest-paid conductor in the country, at $3.5 million. During Levine's tenure, the Metropolitan Opera orchestra expanded its activities into the realms of recording, and separate concert series for the orchestra and chamber ensembles from The Met Orchestra at Carnegie Hall. Levine led the Metropolitan Opera on many domestic and international tours. For the 25th anniversary of his Met debut, Levine conducted the world premiere of John Harbison's The Great Gatsby, commissioned especially to mark the occasion. On his appointment as general manager of the Met, Peter Gelb emphasized that Levine was welcome to remain as long as he wanted to direct music there. Levine was paid $2.1 million by the Met in 2010. Following a series of injuries that began with a fall (see below), Levine's subsequent health problems led to his withdrawal from many Metropolitan Opera conducting engagements. Following a May 2011 performance of Die Walkure, Levine formally withdrew from all conducting engagements at the Met. After two years of physical therapy, Levine returned to conducting with a May 2013 concert with the Metropolitan Opera Orchestra at Carnegie Hall. On September 25, 2013, Levine conducted his first Met performance since May 2011, in a revival production of Cosi fan tutte. Levine was scheduled to conduct three productions at the opera house and three concerts at Carnegie Hall in the 2013-14 season. On April 14, 2016, Met management announced that Levine would step down from his position as Music Director at the end of the 2015-16 season. Levine was paid $1.8 million by the Met for the 2015/16 season. He assumed the new title of Music Director Emeritus, which he held until December 2017, when in the wake of allegations that Levine had sexually abused four young men, the Met suspended its relationship with him and cancelled all his future scheduled performances with the company.
