input: On 29 July 2015, the Afghan government publicly announced that Mohammed Omar had died in 2013. Pakistani newspaper The Express Tribune reported that a former Afghan Taliban minister and current leadership council member, who spoke on condition of anonymity, said Mullah Omar died from tuberculosis. It was confirmed by a senior Taliban member that Omar's death was kept a secret for two years. It is alleged that Omar was "buried somewhere near the border on the Afghan side". The place of Omar's death is disputed; according to Afghan government sources, he died in a hospital in Karachi, Pakistan. A former Taliban minister stated that Karachi was "Omar's natural destination because he had lived there for quite some time and was as familiar with the city as any other resident." However, this claim has been dismissed by other Taliban members, stating that his death occurred in Afghanistan after his health condition had deteriorated due to "sickness" and that "not for a single day did he go to Pakistan". According to an official statement by Pakistani defence minister Khawaja Asif, "Mullah Omar neither died nor was buried in Pakistan and his sons' statements are on record to support this. Whether he died now or two years ago is another controversy which we do not wish to be a part of. He was neither in Karachi nor in Quetta." Initially, some Taliban members denied that he had died. Other sources considered the report to be speculative, designed to destabilise peace negotiations in Pakistan between the Afghan government and the Taliban. Abdul Hassib Seddiqi, the spokesman for Afghanistan's National Directorate of Security (NDS), said: "We confirm officially that he is dead."  The following day, the Taliban confirmed the death of Omar. Sources close to the Taliban leadership said his deputy, Mullah Akhtar Mansour, would replace him, although with the lesser title of Supreme Leader. Omar's eldest son, Mullah Mohammad Yaqoob, was opposed to Mansour's ascension as leader.  The Taliban splinter group Fidai Mahaz claimed Omar did not die of natural causes but was instead assassinated in a coup led by Mullah Akhtar Mansour and Mullah Gul Agha. The Taliban commander, Mullah Mansoor Dadullah, brother of former senior commander Mullah Dadullah, confirmed that Omar had been assassinated. The leader of Fidai Mahaz, Mullah Najibullah, revealed that due to Omar's kidney disease, he needed medicine. According to Najibullah, Mansour poisoned the medicine, damaging Omar's liver and causing him to grow weaker. When Omar summoned Mansour and other members of Omar's inner circle to hear his will, they discovered that Mansour was not to assume leadership of the Taliban. It was due to Mansour allegedly orchestrating "dishonourable deals." When Mansour pressed Omar to name him as his successor, Omar refused. Mansour then shot and killed Omar. Najibullah claimed Omar died at a southern Afghanistan hide-out in Zabul Province in the afternoon on 23 April 2013. Mullah Mohammad Yaqoob, Mullah Omar's elder son, denied that his father had been killed, insisting that he died of natural causes.  Omar's death brought about condolences from Ajnad al-Kavkaz, Ansar al Furqan, Islamic Front's Ahrar al-Sham, Jaish Muhammad, Jabhat Ansar al Din, Turkistan Islamic Party, Jamaat Ansar al Sunnah, Jaish al Ummah, Jamaat ul Ahrar, Caucasus Emirate, Jaish al-Islam, Nusra, AQAP, and AQIM, and Al-Shabaab.

Answer this question "What is another theory?"
output: Whether he died now or two years ago is another controversy

Question: Olivier Eugene Charles Prosper Messiaen (French: [olivje mesja]; December 10, 1908 - April 27, 1992) was a French composer, organist, and ornithologist, one of the major composers of the 20th century. His music is rhythmically complex; harmonically and melodically he employs a system he called modes of limited transposition, which he abstracted from the systems of material generated by his early compositions and improvisations. He wrote music for chamber ensembles and orchestra, vocal music, as well as for solo organ and piano, and also experimented with the use of novel electronic instruments developed in Europe during his lifetime. He travelled widely and wrote works inspired by diverse influences ranging from Japanese music, the landscape of Bryce Canyon in Utah and the life of St. Francis of Assisi.

Messiaen's next work was the large-scale La Transfiguration de Notre Seigneur Jesus-Christ. The composition occupied him from 1965 to 1969 and the musicians employed include a 100-voice ten-part choir, seven solo instruments and large orchestra. Its fourteen movements are a meditation on the story of Christ's Transfiguration. Shortly after its completion, Messiaen received a commission from Alice Tully for a work to celebrate the U.S. bicentennial. He arranged a visit to the US in spring 1972, and was inspired by Bryce Canyon in Utah, where he observed the canyon's distinctive colours and birdsong. The twelve-movement orchestral piece Des canyons aux etoiles... was the result, first performed in 1974 in New York.  In 1971, he was asked to compose a piece for the Paris Opera. While reluctant to undertake such a major project, he was persuaded in 1975 to accept the commission and began work on his Saint-Francois d'Assise. The composition was intensive (he also wrote his own libretto) and occupied him from 1975 to 1979; the orchestration was carried out from 1979 until 1983. Messiaen preferred to describe the final work as a "spectacle" rather than an opera. It was first performed in 1983. Some commentators at the time thought that the opera would be his valediction (at times Messiaen himself believed so), but he continued to compose. In 1984 he published a major collection of organ pieces, Livre du Saint Sacrement; other works include birdsong pieces for solo piano, and works for piano with orchestra.  In the summer of 1978, Messiaen retired from teaching at the Conservatoire. He was promoted to the highest rank of the Legion d'honneur, the Grand-Croix, in 1987. An operation prevented his participation in the celebration of his 70th birthday in 1978, but in 1988 tributes for Messiaen's 80th included a complete performance in London's Royal Festival Hall of St. Francois, which the composer attended, and Erato's publication of a seventeen-CD collection of Messiaen's music including a disc of the composer in conversation with Claude Samuel.  Although in considerable pain near the end of his life (requiring repeated surgery on his back) he was able to fulfil a commission from the New York Philharmonic Orchestra, Eclairs sur l'au-dela..., which was premiered six months after his death. He died in Paris on April 27, 1992.  On going through his papers, Loriod discovered that, in the last months of his life, he had been composing a concerto for four musicians he felt particularly grateful to, namely herself, the cellist Mstislav Rostropovich, the oboist Heinz Holliger and the flautist Catherine Cantin (hence the title Concert a quatre). Four of the five intended movements were substantially complete; Yvonne Loriod undertook the orchestration of the second half of the first movement and of the whole of the fourth with advice from George Benjamin. It was premiered by the dedicatees in September 1994.
