full_context: Document 1: Smell the Roses: "Smell the Roses" is a song by English rock musician and former Pink Floyd member Roger Waters, and the ninth track on his fifth studio album, "Is This the Life We Really Want?" It was released as a single on 20 April 2017, and the album was released on 2 June 2017, by Columbia Records.
Document 2: Us + Them Tour: The Us + Them Tour is an ongoing concert tour by Roger Waters, formerly of Pink Floyd. The tour will visit the United States and Canada, showcasing songs from Waters' career both with Pink Floyd and as a solo artist. Also considered as the tour of his most recent album "Is This the Life We Really Want?", because this is the first time he plays songs from that record. It opened on 26 May 2017 in Kansas City, MO, and the North American leg of the show will end on 28 October 2017 in Vancouver, BC. Waters has revealed that he will take the tour to Australia and New Zealand, and later to Europe, during 2018, and some dates for Europe and Oceania were announced during the month of September 2017.
Document 3: Io (opera): "Io"'s unfinished state meant that it was once believed to be Rameau's last opera, but it contains a duet which appears in revised form in "Les fêtes de Polymnie" (1745). This has led the musicologist Graham Sadler to conclude that "Io" must predate 1745 and that the librettist was Louis de Cahusac, who also wrote the words for "Les fêtes", because French librettists did not borrow from other writers.
Document 4: What God Wants, Part I: "What God Wants, Part I" is the first song in a series of songs written and released by former Pink Floyd bassist, Roger Waters on his third solo album, "Amused to Death". "What God Wants" is separated into three parts, much like Pink Floyd's earlier work with "Another Brick in the Wall". Though the song is in three parts, "What God Wants Pt. 1", was the only one to be released as a single. The song features the guitar playing of Jeff Beck. This part in particular deals with the contradictory duality and hypocrisy perceived by Waters in dogmatic religion and its power over man. The following parts, along with the other songs on the album, deal with worship not only in religion but also in regard to materialism and consumption. All together, its viewpoint is on the power of simplistic conformity; how people adhere to something, not entirely by volition, but out of submission.
Document 5: Excalibur (rock opera): Excalibur is a three-part "Celtic rock opera" written and directed by Breton folk-rock musician Alan Simon, the first part of which premiered in 1998, and was released as an album in the following year under the French title "Excalibur, La légende des Celtes". Its success in France led to two more albums and two novels. In 2009 a spectacular adaptation combining material from the first two albums was performed in Germany under the English title "Excalibur: the Celtic Rock Opera", with great success. It was extended with material from the third album in 2011.
Document 6: Radio K.A.O.S.: Radio K.A.O.S. is a studio album by English rock musician and former Pink Floyd member Roger Waters. Released on 15 June 1987 in the United Kingdom and June 16 in the United States, it was Waters' second solo album after his split from Pink Floyd in 1985. Like his previous and future studio albums and many works of his during his time with Pink Floyd, the album is a concept album that is based on a number of key factors of politics in the late 1980s, including monetarism and its effect on citizens, popular culture of the time, and the events and consequences of the Cold War. It also makes criticisms of Margaret Thatcher's government, much like Pink Floyd's "The Final Cut", another album conceived by Waters. The album follows Billy, a mentally and physically disabled man from Wales, forced to live with his uncle David in Los Angeles after his brother Benny was sent to prison after protesting against the government, following his dismissal from his job in mining due to "market forces". The album explores Billy's mind and view on the world through an on-air conversation between him and Jim, a disc jockey at a local fictitious radio station named Radio KAOS.
Document 7: Armide (Gluck): Gluck set the same libretto Philippe Quinault had written for Lully in 1686, based on Torquato Tasso's "Gerusalemme liberata" ("Jerusalem Delivered"). Gluck seemed at ease in facing French traditions head-on when he composed "Armide". Lully and Quinault were the very founders of serious opera in France and "Armide" was generally recognized as their masterpiece, so it was a bold move on Gluck's part to write new music to Quinault's words. A similar attempt to write a new opera to the libretto of "Thésée" by Jean Joseph de Mondonville in 1765 had ended in disaster, with audiences demanding it be replaced by Lully's original. By utilizing "Armide", Gluck challenged the long-standing and apparently inviolable ideals of French practice, and in the process he revealed these values capable of renewal through "modern" compositional sensitivities. Critical response and resultant polemic resulted in one of those grand imbroglios common to French intellectual life. Gluck struck a nerve in French sensitivities, and whereas "Armide" was not one of his more popular works, it remained a critical touchstone in the French operatic tradition and was warmly praised by Berlioz in his "Memoirs". Gluck also set a minor fashion for resetting Lully/Quinault operas: Gluck's rival Piccinni followed his example with "Roland" in 1778 and "Atys" in 1780; in the same year, Philidor produced a new "Persée"; and Gossec offered his version of "Thésée" in 1782. Gluck himself is said to have been working on an opera based on "Roland", but he abandoned it when he heard Piccinni had taken on the same libretto.
Document 8: Padmâvatî: Padmâvatî is an opera in two acts by the French composer Albert Roussel. The libretto, by Louis Laloy, is based on Théodore-Marie Pavie's "La légende de Padmanî, reine de Tchitor", which retells the legend recounted in Malik Muhammad Jayasi's poem "Padmavat" (1540). It was first performed at the Paris Opéra on June 1, 1923. Roussel styled the work an opéra-ballet and there are many dance numbers and opportunities for spectacle. The composer was inspired by his visit to the ruined city of Chittor in Rajputana (now Rajasthan) and he incorporated many features of Indian music into the score.
Document 9: Samson (opera): Samson was an opera by the French composer Jean-Philippe Rameau with a libretto by Voltaire. The work was never staged due to censorship, although Voltaire later printed his text. Rameau intended the opera on the theme of Samson and Delilah as the successor to his debut "Hippolyte et Aricie", which premiered in October 1733. Like "Hippolyte", "Samson" was a "tragédie en musique" in five acts and a prologue. Voltaire had become a great admirer of Rameau's music after seeing "Hippolyte" and suggested a collaboration with the composer in November 1733. The opera was complete by late summer 1734 and went into rehearsal. However, a work on a religious subject with a libretto by such a notorious critic of the Church was bound to run into controversy and "Samson" was banned. An attempt to revive the project in a new version in 1736 also failed. The score is lost, although Rameau recycled some of the music from "Samson" in his later operas.
Document 10: Is This the Life We Really Want?: Is This the Life We Really Want? (stylised as is this the life we really want?) is the fifth studio album by English rock musician and former Pink Floyd bassist and vocalist Roger Waters, released on 2 June 2017 by Columbia Records. It is his first solo album in nearly 25 years since "Amused to Death" (1992), as well as his first studio album in 12 years since "Ça Ira" (2005). On 20 April, the single "Smell the Roses" was released.
Document 11: Naïs: Naïs is an opera by Jean-Philippe Rameau first performed on 22 April 1749 at the Opéra in Paris. It takes the form of a "pastorale héroïque" in three acts and a prologue. The librettist was Louis de Cahusac, in the fourth collaboration between him and Rameau. The work bears the subtitle "Opéra pour La Paix", which refers to the fact that Rameau composed the opera on the occasion of the Treaty of Aix-la-Chapelle, at the conclusion of the War of the Austrian Succession. Its original title was "Le triomphe de la paix", but criticism of the terms of the treaty led to a change in the title.
Document 12: Candide (operetta): Candide is an operetta with music composed by Leonard Bernstein, based on the 1759 novella of the same name by Voltaire. The operetta was first performed in 1956 with a libretto by Lillian Hellman; but since 1974 it has been generally performed with a book by Hugh Wheeler which is more faithful to Voltaire's novel. The primary lyricist was the poet Richard Wilbur. Other contributors to the text were John Latouche, Dorothy Parker, Lillian Hellman, Stephen Sondheim, John Mauceri, John Wells, and Bernstein himself. Maurice Peress and Hershy Kay contributed orchestrations. Although unsuccessful at its premiere, "Candide" has now overcome the unenthusiastic reaction of early audiences and critics and achieved enormous popularity. It is very popular among major music schools as a student show because of the quality of its music and the opportunities it offers to student singers.
Document 13: Ça Ira (opera): Ça Ira (French for "It'll be fine", subtitled "There is Hope") is the fourth studio album by Roger Waters. It is an opera in three acts and a concept album. The album is based on the French libretto co-written by Étienne and Nadine Roda-Gil on the historical subject of the early French Revolution. "Ça Ira" was released 26 September 2005, as a double CD album featuring baritone Bryn Terfel, soprano Ying Huang, and tenor Paul Groves. The album received mixed reviews, with critics praising the composition but criticising its plot and simplicity.
Document 14: Flickering Flame: The Solo Years Volume 1: Flickering Flame: The Solo Years Volume I is a compilation album of former Pink Floyd member Roger Waters' solo material, released in Europe and Australia in 2002 (see 2002 in music). It was not released in the US and UK until 30 May 2011, when this album along with the rest of the Waters' solo material was released as part of "The Roger Waters Collection" Boxset. The album will be sold separately from the compilation, for a 12-month term.
Document 15: Déjà Vu (Roger Waters song): "Déjà Vu" is a song by English rock musician and former Pink Floyd member Roger Waters, and the second track on his fourth studio album, "Is This the Life We Really Want?" It was released as a single on 8 May 2017, with the album being released on 2 June 2017, by Columbia Records. It was previously known as "Lay Down Jerusalem (If I Had Been God)" when played live before single's official release.
