Problem: Background: 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.
Context: 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.
Question: Did they go on tour?
Answer:

Background: Jean Desire Gustave Courbet (French: [gystav kuRbe]; 10 June 1819 - 31 December 1877) was a French painter who led the Realism movement in 19th-century French painting. Committed to painting only what he could see, he rejected academic convention and the Romanticism of the previous generation of visual artists. His independence set an example that was important to later artists, such as the Impressionists and the Cubists. Courbet occupies an important place in 19th-century French painting as an innovator and as an artist willing to make bold social statements through his work.
Context: In 1855, Courbet submitted fourteen paintings for exhibition at the Exposition Universelle. Three were rejected for lack of space, including A Burial at Ornans and his other monumental canvas The Artist's Studio. Refusing to be denied, Courbet took matters into his own hands. He displayed forty of his paintings, including The Artist's Studio, in his own gallery called The Pavilion of Realism (Pavillon du Realisme) which was a temporary structure that he erected next door to the official Salon-like Exposition Universelle. The work is an allegory of Courbet's life as a painter, seen as an heroic venture, in which he is flanked by friends and admirers on the right, and challenges and opposition to the left. Friends on the right include the art critics Champfleury, and Charles Baudelaire, and art collector Alfred Bruyas. On the left are figures (priest, prostitute, grave digger, merchant and others) who represent what Courbet described in a letter to Champfleury as "the other world of trivial life, the people, misery, poverty, wealth, the exploited and the exploiters, the people who live off death." In the foreground of the left-hand side is a man with dogs, who was not mentioned in Courbet's letter to Champfleury. X-rays show he was painted in later, but his role in the painting is important: he is an allegory of the then current French Emperor, Napoleon III, identified by his famous hunting dogs and iconic twirled moustache. By placing him on the left, Courbet publicly shows his disdain for the emperor and depicts him as a criminal, suggesting that his "ownership" of France is an illegal one. Although artists like Eugene Delacroix were ardent champions of his effort, the public went to the show mostly out of curiosity and to deride him. Attendance and sales were disappointing, but Courbet's status as a hero to the French avant-garde became assured. He was admired by the American James McNeill Whistler, and he became an inspiration to the younger generation of French artists including Edouard Manet and the Impressionist painters. The Artist's Studio was recognized as a masterpiece by Delacroix, Baudelaire, and Champfleury, if not by the public.
