Background: Crowded House are a rock band formed in Melbourne, Australia, in 1985. The founding members were New Zealander Neil Finn (vocalist, guitarist, primary songwriter) and Australians Paul Hester (drums) and Nick Seymour (bass). Later band members included Neil Finn's brother, Tim Finn, and Americans Mark Hart and Matt Sherrod. Originally active from 1985 to 1996, the band had consistent commercial and critical success in Australia and New Zealand and international chart success in two phases, beginning with their self-titled debut album, which reached number twelve on the US Album Chart in 1987 and provided the Top Ten hits
Context: Crowded House were midway through a US tour when Paul Hester quit the band on 15 April 1994. He flew home to Melbourne to await the birth of his first child and indicated that he required more time with his family. Wally Ingram, drummer for support act Sheryl Crow, temporarily filled in until a replacement, Peter Jones (ex-Harem Scarem, Vince Jones, Kate Ceberano's Septet) was found. After the tour, the Finn Brothers released their album Finn in November 1995. In June 1996, at a press conference to announce the release of their greatest hits album Recurring Dream, Neil revealed that Crowded House were to disband. The June 1996 concerts in Europe and Canada were to be their final performances. Recurring Dream contained four songs from each of the band's studio albums, along with three new songs. The album debuted at number one in Australia, New Zealand and the UK in July 1996. Early copies included a bonus CD of live material. The album's three new songs, which were released as singles, were "Instinct", "Not the Girl You Think You Are" and "Everything Is Good for You", which featured backing vocals from Pearl Jam's Eddie Vedder. Paul Hester returned to the band to play drums on the three new tracks. Worried that their goodbye had been too low-key and had disregarded their home fans, the band performed the Farewell to the World concert on the steps of the Sydney Opera House on 24 November 1996, which raised funds for the Sydney Children's Hospital. The concert featured the line-up of Neil Finn, Nick Seymour, Mark Hart and Paul Hester. Tim Finn and Peter Jones both made guest appearances. Support bands on the day were Custard, Powderfinger and You Am I. The concert had one of the highest live audiences in Australian history with the crowd being estimated at between 120,000 and 250,000 people. Farewell to the World was released on VHS in December 1996. In 2007, a double CD and a DVD were issued as to commemorate the concert's tenth anniversary. The DVD featured newly recorded audio commentary by Finn, Hart and Seymour and other new bonus material.

Problem: Background: Oystein Aarseth (Norwegian: ['oystein 'os@t]; 22 March 1968 - 10 August 1993), better known by his stage name Euronymous, was a Norwegian guitarist. Euronymous was a founder of and central figure in the early Norwegian black metal scene. He was a co-founder of the Norwegian black metal band Mayhem. He was also founder and owner of the extreme metal record label Deathlike Silence Productions and record shop Helvete.
Context: In early 1993, animosity arose between Euronymous and Vikernes, and between Euronymous and the Swedish black metal scene. On the night of 10 August 1993, Vikernes and Snorre 'Blackthorn' Ruch drove from Bergen to Euronymous' apartment at Toyengata in Oslo. Upon their arrival a confrontation began and Vikernes fatally stabbed Euronymous. His body was found on the stairs outside the apartment with 23 stab wounds - two to the head, five to the neck, and 16 to the back. Euronymous' murder was initially blamed on Swedish black metallers by the media. It has been speculated that the murder was the result of a power struggle, a financial dispute over Burzum records, or an attempt at "outdoing" the stabbing in Lillehammer. Vikernes denies all of these, claiming that he attacked Euronymous in self-defense. He says that Euronymous had plotted to stun him with an electroshock weapon, tie him up and torture him to death while videotaping the event. Vikernes explains: "If he was talking about it to everybody and anybody I wouldn't have taken it seriously. But he just told a select group of friends, and one of them told me". He said Euronymous planned to use a meeting about an unsigned contract to ambush him. Blackthorn stood outside smoking while Vikernes climbed the stairs to Euronymous' apartment on the fourth floor. Vikernes said he met Euronymous at the door and handed him the contract, but when he stepped forward and confronted Euronymous, Euronymous "panicked" and kicked him in the chest. The two got into a struggle and Vikernes stabbed Euronymous to death. Vikernes defends that most of Euronymous' cut wounds were caused by broken glass he had fallen on during the struggle. After the murder, Vikernes and Blackthorn drove back to Bergen. On the way, they stopped at a lake where Vikernes disposed of his bloodstained clothes. The self-defense story is doubted by Faust and other members of the scene. According to Vikernes, Blackthorn only came along to show Euronymous some new guitar riffs and was "in the wrong place at the wrong time". Blackthorn claims that, in the summer of 1993, he was almost committed to a mental hospital but fled to Bergen and stayed with Vikernes. He said Vikernes planned to murder Euronymous and pressured him into coming along. Blackthorn said of the murder, "I was neither for nor against it. I didn't give a shit about Oystein". Vikernes called Blackthorn's claims a "defense [...] to make sure I couldn't blame him [for the murder]".
Question: Who murdered him?
Answer:
Vikernes fatally stabbed Euronymous.
