Problem: Background: Alfred Cellier (1 December 1844 - 28 December 1891) was an English composer, orchestrator and conductor. In addition to conducting and music directing the original productions of several of the most famous Gilbert and Sullivan works and writing the overtures to some of them, Cellier conducted at many theatres in London, New York and on tour in Britain, America and Australia. He composed over a dozen operas and other works for the theatre, as well as for orchestra, but his 1886 comic opera, Dorothy, was by far his most successful work. It became the longest-running piece of musical theatre in the nineteenth century.
Context: In December 1877 Cellier joined the D'Oyly Carte company as musical director at the Opera Comique in London. There he conducted The Sorcerer (1877), H.M.S. Pinafore (1878, for which he wrote the overture, based on themes from the opera), Trial by Jury (1878), George Grossmith's Cups and Saucers (1878-79), and three of his own one-act works: Dora's Dream (1877-78 revival), The Spectre Knight (1878), and After All! (1878-79). Cellier was conducting the performance of Pinafore during which the partners of The Comedy Opera Company attempted to repossess the set, and he was noted for his attempts to calm the audience during the fracas. His brother, Francois, succeeded him as musical director at the Opera Comique in 1879. Alfred Cellier was a conductor of a series of promenade concerts at the Queen's Theatre, Long Acre and, in 1878-1879 he was joint conductor, with Sullivan, of the Covent Garden Promenade Concerts.  In 1879, he travelled with Gilbert, Sullivan, and Carte to America, where he acted as conductor for Pinafore and The Pirates of Penzance, with Carte's first American touring company. Cellier prepared the overture to Pirates using Sullivan's music from the rest of the score. Back in London in July 1880, he directed the music at the Opera Comique for Pirates and another of his own pieces with Desprez, In the Sulks. In April 1881, he left the D'Oyly Carte company, ceding the baton to his brother. Cellier composed a three-act grand opera, Pandora, a version of Longfellow's The Masque of Pandora (with a libretto by B. C. Stephenson) that was presented in Boston in 1881. He returned to America later that year as music director of D'Oyly Carte's New York and touring productions of Billee Taylor (1882), Les Manteaux Noirs and Rip Van Winkle (both in the fall of 1882), and Iolanthe (1882-83), for the latter of which he prepared the New York overture.  In 1883, Cellier's setting of Gray's Elegy, in the form of a cantata, was produced at the Leeds music festival. In 1883, Cellier left the D'Oyly Carte company, but he was back for brief periods as music director with D'Oyly Carte's touring companies for Princess Ida (1884) and The Mikado (1885). In 1885, also, Cellier composed incidental music for a production of As You Like It. He composed two more companion pieces that had Savoy Theatre premieres: The Carp (performed with The Mikado and Ruddigore in 1886-87), and Mrs. Jarramie's Genie (composed together with his brother Francois, with libretti by Desprez, which played together with several different operas at the Savoy between 1887 and 1889).  While in London, Cellier conducted at several London theatres, including the Criterion, the St James's, and the Savoy. Later, as a result of ill health, he resided abroad, notably in America and Australia, where he was a representative for the D'Oyly Carte company.

Answer: 

Background: Atsuko Maeda (Qian Tian  Dun Zi , Maeda Atsuko, born July 10, 1991, in Ichikawa, Chiba) is a Japanese singer and actress known for her work in the Japanese idol group AKB48. Maeda was one of the most prominent members in the group, and placed first among all AKB48 and sister group candidates in the group's general 2009 and 2011 elections, and second in the 2010 election. She also appeared on many of its album covers. On March 25, 2012, she announced her graduation from AKB48; it was held on August 27.
Context: At age 14, Maeda became a member of AKB48's first group, Team A, which composed of 24 girls and debuted on December 8, 2005.  In 2009, Maeda won the first edition of AKB48's annual general elections, which are described as a popularity contest. As a result, she was the headlined performer for the group's 13th single, "Iiwake Maybe". The following year, she placed second overall, but still had a significant choreography position in the lineup for "Heavy Rotation". Later that year, AKB48 employed a rock-paper-scissors tournament to determine the top spot of AKB48's 19th major single "Chance no Junban". Maeda placed 15th, which secured her a spot on title track. Maeda would also win the group's third general election held in 2011.  Maeda was one of the members who sang on every AKB48 title track since the group's inception. Her streak of A-side appearances ended in 2011, when she lost to Team K captain Sayaka Akimoto at a rock-paper-scissors tournament which determined the featured members for the group's 24th single "Ue kara Mariko".  On March 25, 2012, during an AKB48 Concert at the Saitama Super Arena, Maeda announced that she would leave the group. This caused a large buzz in the Japanese news, and spawned a rumor (later proved false) that a student from University of Tokyo had committed suicide over the announcement. AKB48 later announced that Maeda would leave after the Tokyo Dome concerts; For her final performance, there were 229,096 requests filed for seat tickets. Her farewell performance and ceremony occurred on August 27 at the AKB48 theater, and was streamed live on YouTube.
