Its second single "Judas" followed two months later, and "The Edge of Glory" served as its third single. Both reached the top 10 in the US and the UK.

The following article contains an answer for the question: Whose help is sought to free someone from the spell of a mirror? , can you please find it?   The film takes place in two different times: the present and 11 years earlier. The two plot lines are told in parallel through flashbacks. In 2002, software engineer Alan Russell moves into a new house with his wife Marie, 10-year-old son Tim, and 12-year-old daughter Kaylie. Alan purchases an antique mirror to decorate his office. Unbeknownst to them, the mirror supernaturally induces hallucinations. Marie is haunted by visions of her own body decaying, while Alan is seduced by a ghostly woman named Marisol, who has mirrors in place of eyes. Over time, the parents become psychotic; Alan isolates himself in his office, and Marie becomes withdrawn and paranoid. All of the plants in the house die, and the family dog disappears after being shut in the office with the mirror. After Kaylie sees Alan with Marisol, she tells her mother, and the parents fight. One night, Marie goes insane and attempts to kill her children, but Alan locks her away. When the family runs out of food, the children realize that their father is under the influence of the mirror, so Kaylie goes to seek help from their mother, and finds her chained to the wall, acting like an animal. Kaylie and Tim try going to their neighbors for help, but the neighbors disbelieve their stories. When Kaylie attempts to use the phone, she discovers that all of her phone calls are answered by the same man.

Problem: Given the question: The following article contains an answer for the question: Whose opera, The Voyevoda, contained a piece that had been promised to the Russian Music Society? , can you please find it?   In 1867, Rubinstein handed over the directorship of the Conservatory to Zaremba. Later that year he resigned his conductorship of the Russian Music Society orchestra, to be replaced by Balakirev. Tchaikovsky had already promised his Characteristic Dances (then called Dances of the Hay Maidens) from his opera The Voyevoda to the society. In submitting the manuscript (and perhaps mindful of Cui's review of the cantata), Tchaikovsky included a note to Balakirev that ended with a request for a word of encouragement should the Dances not be performed.At this point The Five as a unit was dispersing. Mussorgsky and Rimsky-Korsakov wanted to remove themselves from Balakirev's influence, which they now found stifling, and go in their individual directions as composers. Balakirev might have sensed a potential new disciple in Tchaikovsky. He explained in his reply from Saint Petersburg that while he preferred to give his opinions in person and at length to press his points home, he was couching his reply "with complete frankness", adding, with a deft touch of flattery, that he felt that Tchaikovsky was "a fully fledged artist" and that he looked forward to discussing the piece with him on an upcoming trip to Moscow.These letters set the tone for Tchaikovsky's relationship with Balakirev over the next two years. At the end of this period, in 1869, Tchaikovsky was a 28-year-old professor at the Moscow Conservatory. Having written his first symphony and an opera, he next composed a symphonic poem entitled Fatum. Initially pleased with the piece when Nikolai Rubinstein conducted it in Moscow, Tchaikovsky dedicated it to Balakirev and sent it to him to conduct in Saint Petersburg. Fatum received only a lukewarm reception there. Balakirev wrote a detailed letter to Tchaikovsky in which he explained what he felt were defects in Fatum but also gave some encouragement. He added that he considered the dedication of the music to him as "precious to me as a sign of your sympathy towards me—and I feel a great weakness for you"....

Tchaikovsky
