Problem: Celtic Frost () were a Swiss heavy metal band from Zurich. They are known for their strong influence on the development of extreme metal. Formed in 1982 as Hellhammer, the band became Celtic Frost in 1984 and was active until 1993. It re-formed in 2001 and disbanded following frontman Tom Gabriel Fischer's departure in 2008.

One of their more influential recordings was 1985's To Mega Therion which did not feature Ain on bass, but stand-in Dominic Steiner. The cover artwork is a painting by H.R. Giger entitled Satan I. The album was a major influence on the then-developing death metal and black metal genres. Ain did return after the album was recorded however. In 1987 followed Into the Pandemonium. The album is more varied than many of Celtic Frost's past LPs, with unlikely covers (Wall of Voodoo's "Mexican Radio"), emotionally charged love songs, the album's recurring industrial-influenced rhythmic songs of demons and destruction, traditional Frost styled songs about dreams and fear, and a dark, classical piece with female vocals.  The album is vastly different from the band's previous work and cemented its late 80s avant-garde metal term; it is also a departure from the extreme style found on the band's previous albums, Morbid Tales and To Mega Therion that Celtic Frost had become known for. However, it does have the recurring symphonic elements found on previous albums. The album has a more classic heavy metal style within the songs with elements of industrial, classical and gothic rock, and even has an industrial/electronic body music (EBM)-inspired rhythm in "One in Their Pride". It does have a few black metal elements remaining in Warrior's vocals, though, and some thrash-influenced guitar riffs.  These albums were some of the pivotal LPs for underground metal and introduced a new and more varied sound. Celtic Frost, along with Venom and Bathory were pioneers in the still underground black metal scene, although Celtic Frost were much more experimental with the addition of classical instruments, operatic female vocals and sampling. Celtic Frost was often labeled by critics as avant-garde metal.

Did they do any live performances?

Answer with quotes: 

Background: Andriana refers to both the noble class and a title of nobility in Madagascar. Historically, many Malagasy ethnic groups lived in highly stratified caste-based social orders in which the andriana were the highest strata. They were above the Hova (free commoner castes) and Andevo (slaves). The Andriana and the Hova were a part of Fotsy, while the Andevo were Mainty in local terminology.
Context: The Andriana caste were originally the source of nobility and they specialized in the rituals and warrior occupations in the Merina society. However, in 19th century when Merina conquered the other kingdoms and ruled most of the island, a much larger army was needed, and the soldiers then included the Hova caste as well.  The Andriana benefited from numerous privileges in precolonial Madagascar. Land ownership in Imerina was reserved for the andriana class, who ruled over fiefs called menakely. The populace under the rule of an andriana lord owed him--and the king--a certain amount of free labor each year (fanompoana) for public works such as the construction of dikes, rice paddies, roads and town walls. Posts of privilege within the government, such as judges or royal advisers, were likewise reserved for certain groups of andriana.  The valiha, the national instrument of Madagascar, was originally an instrument of the masses but came to be affiliated with the noble class in the 19th century. The valiha featured heavily in the music of the Merina royal court performed at palaces such as Ambohimanga or the Rova at Antananarivo. The strings of the valiha were more easily plucked with the fingernails, which were commonly grown long for this purpose; long fingernails became fashionable and symbolic of belonging to the andriana class within the Kingdom of Imerina.  At Antananarivo, only andriana tombs were allowed to be constructed within town limits. Hovas (freemen) and slaves were required to bury their dead beyond the city walls. The highest ranks of andriana were permitted to distinguish their tombs by the construction of a small, windowless wooden tomb house on top of it, called a trano masina (sacred house) for the king and trano manara (cold house) for the Zanakandriana, Zazamarolahy and Andriamasinavalona. This tradition may have originated with King Andriantompokoindrindra, who is said to have ordered the first trano masina to be built on his tomb in honor of his memory.

Question:
Rockefeller was born in New York City, New York. He grew up in an eight-story house at 10 West 54th Street, the tallest private residence ever built in the city. Rockefeller was the youngest of six children born to financier John Davison Rockefeller Jr. and socialite Abigail Greene "Abby" Aldrich. John Jr. was the only son of Standard Oil co-founder John Davison Rockefeller Sr. and schoolteacher Laura Celestia "Cettie" Spelman.
Rockefeller traveled widely and met with both foreign rulers and U.S. presidents, beginning with Dwight D. Eisenhower. At times he served as an unofficial emissary on high-level business. Among the foreign leaders he met were Saddam Hussein, Fidel Castro, Nikita Khrushchev, and Mikhail Gorbachev.  In 1968, he declined an offer from his brother Nelson Rockefeller, then governor of New York, to appoint him to Robert F. Kennedy's Senate seat after Kennedy was assassinated in June 1968, a post Nelson also offered to their nephew John Davison "Jay" Rockefeller IV. President Jimmy Carter offered him the position of United States Secretary of the Treasury but he declined.  Rockefeller was criticized for befriending foreign autocrats in order to expand Chase interests in their countries. The New York Times columnist David Brooks wrote in 2002 that Rockefeller "spent his life in the club of the ruling class and was loyal to members of the club, no matter what they did." He noted that Rockefeller had cut profitable deals with "oil-rich dictators", "Soviet party bosses" and "Chinese perpetrators of the Cultural Revolution".  Rockefeller met Henry Kissinger in 1954, when Kissinger was appointed a director of a seminal Council on Foreign Relations study group on nuclear weapons, of which David Rockefeller was a member. He named Kissinger to the board of trustees of the Rockefeller Brothers Fund, and consulted with him frequently, with the subjects including the Chase Bank's interests in Chile and the possibility of the election of Salvador Allende in 1970. Rockefeller supported his "opening of China" initiative in 1971 as it afforded banking opportunities for the Chase Bank.  Though a lifelong Republican and party contributor, he was a member of the moderate "Rockefeller Republicans" that arose out of the political ambitions and public policy stance of his brother Nelson. In 2006 he teamed up with former Goldman Sachs executives and others to form a fund-raising group based in Washington, Republicans Who Care, that supported moderate Republican candidates over more ideological contenders.
