Problem: 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.

Daniel Barenboim was born in 1942 in Buenos Aires, Argentina, to Argentinian-Jewish parents Aida (nee Schuster) and Enrique Barenboim. He started piano lessons at the age of five with his mother, continuing to study with his father, who remained his only teacher. On 19 August 1950, at the age of seven, he gave his first formal concert in his hometown, Buenos Aires. In 1952, Barenboim's family moved to Israel. Two years later, in the summer of 1954, his parents took him to Salzburg to take part in Igor Markevitch's conducting classes. During that summer he also met and played for Wilhelm Furtwangler, who has remained a central musical influence and ideal for Barenboim. Furtwangler called the young Barenboim a "phenomenon" and invited him to perform the Beethoven First Piano Concerto with the Berlin Philharmonic, but Barenboim's father considered it too soon after the Second World War for a child of Jewish parents to be performing in Berlin. In 1955 Barenboim studied harmony and composition with Nadia Boulanger in Paris. On 15 June 1967, Barenboim and British cellist Jacqueline du Pre were married in Jerusalem at a Western Wall ceremony, Du Pre having converted to Judaism. Acting as one of the witnesses was the conductor Zubin Mehta, a long-time friend of Barenboim. Since "I was not Jewish I had to temporarily be renamed Moshe Cohen, which made me a 'kosher witness'," Mehta recalled. Du Pre retired from music in 1973, after being diagnosed with multiple sclerosis (MS). The marriage lasted until du Pre's death in 1987. In the early 1980s, Barenboim began an affair with the Russian pianist Elena Bashkirova, with whom he had two sons born in Paris before du Pre's death: David Arthur, born 1983, and Michael, born 1985. Barenboim worked to keep his relationship with Bashkirova hidden from du Pre, and believed he had succeeded. He and Bashkirova married in 1988. Both sons are part of the music world: David is a manager-writer for the German hip-hop band Level 8, and Michael Barenboim is a classical violinist.

Answer with quotes:

Problem: Lopes was born in Philadelphia, Pennsylvania, the daughter of Wanda Denise (nee Andino), a seamstress, and Ronald Lopes Sr., a US Army staff sergeant, of Portuguese background. She had a younger brother, Ronald Jr., and a younger sister, Raina Anitra (who professionally goes by Reigndrop). Lopes said her father was "very strict, very domineering" and that he treated the family like they were in "boot camp". He was a "talented musician" and played the harmonica, clarinet, piano, and saxophone.

At the age of 19, having heard of an open casting call for a new girl group through her then-boyfriend, Lopes moved to Atlanta to audition. Originally starting as a female trio called 2nd Nature, the group had been renamed TLC, derived from the first initials of its members at the time: Tionne, Lisa and Crystal. Things did not work out with Crystal Jones, and TLC's manager Perri "Pebbles" Reid brought in Damian Dame backup dancer Rozonda Thomas as a third member of the group. To preserve the band's original name, Rozonda needed a name starting with C, and so became Chilli, a name chosen by Lopes. Bandmate Tionne Watkins became T-Boz, derived from the first letter of her first name and "Boz" (slang for "boss"). Lopes was renamed "Left Eye" after a compliment from a man who once told her he was attracted to her because of her left eye. Lopes emphasized her nickname by wearing a pair of glasses with the left lens covered with a condom, in keeping with the group's promotion of safe sex, wearing a black stripe under her left eye, and eventually getting her left eyebrow pierced. The group arrived on the music scene in 1992 with the album Ooooooohhh... On the TLC Tip. With four singles, it sold six million copies worldwide, leading to the group becoming a household name. Two years later CrazySexyCool was released, selling over 23 million copies worldwide, and cemented TLC as one of the biggest female groups of all time. TLC's third album, FanMail, was released in 1999 and sold over 14 million copies worldwide. Its title was a tribute to TLC's loyal fans and the sleeve contained the names of hundreds of them as a "thank you". During the recording of FanMail, a public conflict began amongst the members of the group. In the May 1999 issue of Vibe magazine, Lopes said, "I've graduated from this era. I cannot stand 100 percent behind this TLC project and the music that is supposed to represent me." In response to Lopes' comments, Watkins and Thomas stated to Entertainment Weekly that Lopes "doesn't respect the whole group" and "Left Eye is only concerned with Left Eye." In response, Lopes sent a reply through Entertainment Weekly issuing a "challenge" to Watkins and Thomas to release solo albums and let the public decide who was the "greatest" member of TLC: T-Boz and Chilli declined to take up the challenge, though Lopes always maintained it was a great idea. Things were heated between the ladies for some time, with Thomas speaking out against Lopes, calling her antics "selfish", "evil", and "heartless". TLC then addressed these fights by saying that they are very much like sisters that have their disagreements every now and then as Lisa stated, "It's deeper than a working relationship. We have feelings for each other, which is why we get so mad at each other. I usually say that you cannot hate someone unless you love them. So, we love each other. That's the problem."
