Question: Mazzy Star is an American alternative rock band formed in Santa Monica, California, in 1989 from remnants of the group Opal. Founding member David Roback's friend Hope Sandoval became the group's vocalist when Kendra Smith left Opal. Mazzy Star is best known for the song "Fade into You" which brought the band some success in the mid-1990s and was the group's biggest mainstream hit, earning extensive exposure on MTV, VH1, and radio airplay. Roback and Sandoval are the creative center of the band, with Sandoval as lyricist and Roback as composer of the majority of the band's material.

In Mazzy Star, Roback plays guitar, keyboard, and piano. He wrote almost all music for Mazzy Star, and he has also produced all their recordings. Roback grew up in Pacific Palisades, California, graduating from Palisades High School in 1975. He started a band called Rain Parade with his brother Steven. They first hit the scene in 1982 as part of a loose aggregate of psychedelic 1960s-influenced guitar bands in Los Angeles, and they were in the forefront of that movement which lasted a couple of years. After Rain Parade's first album and tours, Roback left the band. He then became involved with ex-Dream Syndicate bassist Kendra Smith and formed a new band called Clay Allison in 1983. The recordings from the summer this year remained unreleased until the 1989 release of Opal Early Recordings. After Clay Allison's 1984 tour, the band decided to go with a name change, and went from Clay Allison to Opal, whose sound was defined by Roback's spare, distorted guitar work and Smith's vocals. They released the Northern Line EP in 1985. SST Records signed Opal and released their album Happy Nightmare Baby on December 14, 1987. During the Opal tour in December 1987, Smith left the band. She was replaced by Sandoval, and they toured Europe through early 1988. Roback and Sandoval had an intimate relationship at this time and after Opal was disbanded, they took the remaining members of Opal and changed their name to Mazzy Star. Roback currently resides in London, although he spent most of the past decade living in Norway.

Question: David William Donald Cameron (; born 9 October 1966) is a British politician who was Prime Minister of the United Kingdom from 2010 to 2016 and Leader of the Conservative Party from 2005 to 2016. He was Member of Parliament (MP) for Witney from 2001 to 2016. Cameron identifies as a One-Nation Conservative, and has been associated with both economically liberal and socially liberal policies. Born in London to wealthy upper middle-class parents, Cameron was educated at Heatherdown School, Eton College, and Brasenose College, Oxford.

The Conservatives' unexpected success in the 1992 election led Cameron to hit back at older party members who had criticised him and his colleagues, saying "whatever people say about us, we got the campaign right," and that they had listened to their campaign workers on the ground rather than the newspapers. He revealed he had led other members of the team across Smith Square to jeer at Transport House, the former Labour headquarters. Cameron was rewarded with a promotion to Special Adviser to the Chancellor of the Exchequer, Norman Lamont. Cameron was working for Lamont at the time of Black Wednesday, when pressure from currency speculators forced the pound sterling out of the European Exchange Rate Mechanism. At the 1992 Conservative Party conference, Cameron had difficulty trying to arrange to brief the speakers in the economic debate, having to resort to putting messages on the internal television system imploring the mover of the motion, Patricia Morris, to contact him. Later that month Cameron joined a delegation of Special Advisers who visited Germany to build better relations with the Christian Democratic Union; he was reported to be "still smarting" over the Bundesbank's contribution to the economic crisis. Lamont fell out with John Major after Black Wednesday and became highly unpopular with the public. Taxes needed to be raised in the 1993 Budget, and Cameron fed the options Lamont was considering through to Conservative Campaign Headquarters for their political acceptability to be assessed. By May 1993, the Conservatives' average poll rating dropped below 30%, where they would remain until the 1997 general election. Major and Lamont's personal ratings also declined dramatically. However, Lamont's unpopularity did not necessarily affect Cameron: he was considered as a potential "kamikaze" candidate for the Newbury by-election, which includes the area where he grew up. However, Cameron decided not to stand. During the by-election, Lamont gave the response "Je ne regrette rien" to a question about whether he most regretted claiming to see "the green shoots of recovery" or admitting to "singing in his bath" with happiness at leaving the European Exchange Rate Mechanism. Cameron was identified by one journalist as having inspired this gaffe; it was speculated that the heavy Conservative defeat in Newbury may have cost Cameron his chance of becoming Chancellor himself, even though as he was not a Member of Parliament he could not have been. Lamont was sacked at the end of May 1993, and decided not to write the usual letter of resignation; Cameron was given the responsibility to issue to the press a statement of self-justification.
