Problem: Background: Avenged Sevenfold (sometimes abbreviated as A7X) is an American heavy metal band from Huntington Beach, California, formed in 1999. The band's current lineup consists of lead vocalist M. Shadows, rhythm guitarist and backing vocalist Zacky Vengeance, lead guitarist and backing vocalist Synyster Gates, bassist and backing vocalist Johnny Christ, and drummer Brooks Wackerman. Avenged Sevenfold is known for its diverse rock sound and dramatic imagery in album covers and merchandise. Avenged Sevenfold emerged with a metalcore sound on the band's debut Sounding the Seventh Trumpet and continued this sound through their second album Waking the Fallen.
Context: In January 2009, M. Shadows confirmed that the band was writing the follow-up to their self-titled fourth album within the upcoming months. They also played at Rock on the Range, from May 16-17, 2009. On April 16, they performed a version of Guns N' Roses' "It's So Easy" onstage with Slash, at the Nokia Theater in Los Angeles. On December 28, 2009, the band's drummer James "The Rev" Sullivan was found dead at his home at the age of 28. Autopsy results were inconclusive, but on June 9, 2010, the cause of death was revealed to have been an "acute polydrug intoxication due to combined effects of Oxycodone, Oxymorphone, Diazepam/Nordiazepam and ethanol". In a statement by the band, they expressed their grief over the death of The Rev and later posted a message from Sullivan's family which expressed their gratitude to his fans for their support. The band members admitted in a number of interviews that they considered disbanding at this point in time. However, on February 17, 2010, Avenged Sevenfold stated that they had entered the studio, along with now-former Dream Theater drummer Mike Portnoy, to drum for the album, in place of The Rev.  The single "Nightmare" was digitally released on May 18, 2010. A preview for the song was released on May 6, 2010 on Amazon.com, but was removed soon after for unknown reasons. Mixing for the album had been completed in New York City, and Nightmare was finally released worldwide on July 27, 2010. It met with mixed to positive reviews from music critics but was well received by the fans. Nightmare beat sales projections easily, debuting at number one on the Billboard 200 with sales of 163,000 units in its first week. After finishing recording, in December, Portnoy and the band posted simultaneous statements on their websites stating that he would not be their replacement for The Rev. However, Portnoy did travel with the band overseas in December 2010 for three shows in Iraq and Kuwait sponsored by the USO. They played for U.S. Soldiers at Camp Adder, Camp Beuhring, and Balad Air Base. On January 20, 2011, Avenged Sevenfold announced via Facebook that former Confide drummer Arin Ilejay would begin touring with them that year. He was not yet considered a full-time member at this point.  Avenged Sevenfold performed at the Rock am Ring and Rock im Park festivals on June 3-5, 2011 alongside other bands such as Alter Bridge, System of a Down, and In Flames. On April 2011, the band headlined the Golden God Awards held by Metal Hammer. The same night the band won three awards for "Best Vocalist" (M. Shadows), "Epiphone Best Guitarist(s)" (Synyster Gates and Zacky Vengeance) and "Affliction's Album of The Year: " for Nightmare, while Mike Portnoy won the award for "Drum Workshop's Best Drummer" for his work on the album.  Avenged Sevenfold headlined the 2011 Uproar Festival with supporting acts Three Days Grace, Seether, Bullet for My Valentine, Escape The Fate, among others. In November and December 2011, the band went on their "Buried Alive" tour with supporting acts Hollywood Undead, Asking Alexandria, and Black Veil Brides.
Question: is the death of the rev and nightmare the name of an album?
Answer: 

Problem: Background: Kwame Nkrumah PC (21 September 1909 - 27 April 1972) was a Ghanaian politician and revolutionary. He was the first prime minister and president of Ghana, having led it to independence from Britain in 1957. An influential advocate of Pan-Africanism, Nkrumah was a founding member of the Organization of African Unity and winner of the Lenin Peace Prize in 1962. After twelve years abroad pursuing higher education, developing his political philosophy, and organizing with other diasporic pan-Africanists, Nkrumah returned to Gold Coast to begin his political career as an advocate of national independence.
Context: Nkrumah returned to London in May 1945 and enrolled at the London School of Economics as a PhD candidate in anthropology. He withdrew after one term and the next year enrolled at University College, with the intent to write a philosophy dissertation on "Knowledge and Logical Positivism". His supervisor, A. J. Ayer, declined to rate Nkrumah as a "first-class philosopher", saying, "I liked him and enjoyed talking to him but he did not seem to me to have an analytical mind. He wanted answers too quickly. I think part of the trouble may have been that he wasn't concentrating very hard on his thesis. It was a way of marking time until the opportunity came for him to return to Ghana." Finally, Nkrumah enrolled in, but did not complete, a study in law at Gray's Inn.  Nkrumah spent his time on political organising. He and Padmore were among the principal organizers, and co-treasurers, of the Fifth Pan-African Congress in Manchester (15-19 October 1945). The Congress elaborated a strategy for supplanting colonialism with African socialism. They agreed to pursue a federal United States of Africa, with interlocking regional organizations, governing through separate states of limited sovereignty. They planned to pursue a new African culture without tribalism, democratic within a socialist or communist system, synthesizing traditional aspects with modern thinking, and for this to be achieved by nonviolent means if possible. Among those who attended the congress was the venerable W. E. B. Dubois along with some who later took leading roles in leading their nations to independence, including Hastings Banda of Nyasaland (which became Malawi), Jomo Kenyatta of Kenya, Obafemi Awolowo of Nigeria, and C. L. R. James.  The congress sought to establish ongoing African activism in Britain in conjunction with the West African National Secretariat (WANS) to work towards the decolonization of Africa. Nkrumah became the secretary of WANS. In addition to seeking to organise Africans to gain their nations' freedom, Nkrumah sought to succor the many West African seamen who had been stranded, destitute, in London at the end of the war, and established a Coloured Workers Association to empower and succor them. The U.S. State Department and MI5 watched Nkrumah and the WANS, focusing on their links with Communism. Nkrumah and Padmore established a group called The Circle to lead the way to West African independence and unity; the group aimed to create a Union of African Socialist Republics. A document from The Circle, setting forth that goal, was found on Nkrumah upon his arrest in Accra in 1948, and was used against him by the British authorities.
