input: Please answer the following: Given the following context:  By the end of the 1960s, Ornette Coleman had become one of the most influential musicians in jazz after pioneering its most controversial subgenre, free jazz, which jazz critics and musicians initially derided for its deviation from conventional structures of harmony and tonality. In the mid-1970s, he stopped recording free jazz, recruited electric instrumentalists, and pursued a new creative theory he called harmolodics. According to Coleman's theory, all the musicians are able to play individual melodies in any key, and still sound coherent as a group. He taught his young sidemen this new improvisational and ensemble approach, based on their individual tendencies, and prevented them from being influenced by conventional styles. Coleman likened this group ethic to a spirit of "collective consciousness" that stresses "human feelings" and "biological rhythms", and said that he wanted the music, rather than himself, to be successful. He also started to incorporate elements from other styles into his music, including rock influences such as the electric guitar and non-Western rhythms played by Moroccan and Nigerian musicians.Of Human Feelings was a continuation of the harmolodics approach Coleman had applied with Prime Time, an electric quartet introduced on his 1975 album Dancing in Your Head. The group comprised guitarists Charlie Ellerbee and Bern Nix, bassist Jamaaladeen Tacuma, and drummers Ronald Shannon Jackson and Denardo Coleman, Ornette Coleman's son. Tacuma was still in high school when Coleman enlisted him, and first recorded with Prime Time in 1975 for the album Body Meta, which was released in 1978. Tacuma had played in an ensemble for jazz organist Charles Earland, but Earland dismissed him as he felt audiences gave excessive attention to his playing. Coleman found Tacuma's playing ideal for harmolodics and encouraged him not to change. Although Coleman's theory initially challenged his knowledge and perception of music, Tacuma came to like the unconventional role each band member was given as a...  answer the following question:  What is the last name of the person who started to incorporate elements from other styles into his music?

Please answer this: Given the following context:  The opening scene sees "The Man" being approached and attacked by two muggers in a dark alley of London. As the muggers check their seemingly unconscious victim for cash, The Man regains consciousness and brutally kills them. Around that time, Inspector Peter Neilson is investigating the apparent murder scene of the young Melissa and Nikki. In a flashback, the two girls are shown in a goth club looking to pick up men. Melissa spotted The Man and took him home. After spending the night with him, she began hallucinating about the people around turning to her with monstrous faces and voices. Melissa went to Nikki's house to seek help, then a creature burst out of Melissa's womb and attacked Nikki, killing both. Sophie and Emma break into a house in a burglary attempt. When Emma finds a box of money under a bed, a bony old man pops up from the bedcovers and attacks her. The girls stab and bludgeon the old man multiple times before he finally dies. Intending to keep the loot to herself and seeing Emma as a liability for revealing their plan to her sister, Sophie kills Emma and runs home. There, the re-animated bodies of Emma and the old man appear and stab Sophie to death. As the dead bodies are identified, Inspector Neilson links them to an earlier case he had solved in the past. The case involved a man named Kemper, former hypnotist and son of an infamous Satanist.

Problem: Given the following context:  Tony Rivers, a troubled teenager at Rockdale High, is known for losing his temper and overreacting. A campus fight between Tony and classmate Jimmy gets the attention of the local police, Det. Donovan in particular. Donovan breaks up the fight and advises Tony to talk with a "psychologist" that works at the local aircraft plant, Dr. Alfred Brandon, a practitioner of hypnotherapy. Tony declines, but his girlfriend Arlene, as well as his widowed father, show concern about his violent behavior. Later, at a Halloween party at the "haunted house", an old house at which several of the teenagers hang out, Tony attacks his friend Vic after being surprised from behind. After seeing the shocked expressions on his friends's faces, he realizes he needs help and goes to see Dr. Brandon. On Tony's first visit, however, Brandon makes it clear that he has his own agenda while the teenager lies on the psychiatrist's couch: Tony will be an excellent subject for his experiments with a scopolamine serum he has developed that regresses personalities to their primitive instincts. Brandon believes that the only future that mankind has is to "hurl him back to his primitive state." Although Brandon's assistant, Dr. Hugo Wagner, protests that the experiment might kill Tony, Brandon continues and within two sessions suggests to Tony that he was once a wild animal.  answer the following question:  Whose father is concerned about their behavior?

A: Tony

input question: Given the following context:  SVT selects performers for the entries. Artists who perform the demo of a song automatically enter the competition; they must perform their songs if suitable alternate performers cannot be found. The artists' songs risk disqualification if they refuse. In the past, this rule led to the disqualification of, among others, Carola's "När löven faller" in 2003 and Stephen Simmonds's "So Good" in 2006. SVT may also give songs to other performers without considering the interests of the demo artist. This prevented the Brandsta City Släckers (in 2004) and Pernilla Wahlgren (in 2005) from performing the songs they had submitted. Replacements for disqualified songs fare unpredictably at the competition. In 2006, "Naughty Boy" by Hannah Graaf (the replacement for Simmonds' song) finished second to last in its semi-final. In 2002 and 2007, by contrast, the replacements performed by Jan Johansen and Måns Zelmerlöw reached the final ten. The contestants that will perform the twenty-eight qualifiers from the preselection are announced in late November. Singer-songwriters are common. As such, artists often confirm that they will participate before the official announcement. The wildcard (joker) system was introduced in 2004 to diversify the music featured. Four artists, one in each semi-final, were invited by SVT to enter a song of their choice into the competition, provided it does not breach the rules. The wildcard songs and artists were announced in January. Since the wildcards' introduction, three have won the competition. In 2011 there were 15 wildcards. The wildcard system was discontinued in 2013.  answer the following question:  What are the names of the performers who were prevented from preforming songs they had submitted????
output answer:
Brandsta City Släckers
