Pieter Willem Botha, DMS (Afrikaans pronunciation: ['pit@r 'v@l@m 'bU@ta]; 12 January 1916 - 31 October 2006), commonly known as "P. W." and Die Groot Krokodil (Afrikaans for "The Big Crocodile"), was the leader of South Africa from 1978 to 1989, serving as the last Prime Minister from 1978 to 1984 and the first executive State President from 1984 to 1989. First elected to Parliament in 1948, Botha was an outspoken opponent of majority rule and international communism. However, his administration did make concessions towards political reform, whereas internal unrest saw widespread human rights abuses at the hands of the government. Botha resigned the leadership of the ruling National Party in February 1989 after suffering a stroke and six months later was coerced to leave the presidency as well.
In superficial ways, Botha's application of the apartheid system was less repressive than that of his predecessors. He legalised interracial marriage and miscegenation, both completely banned since the late 1940s. The constitutional prohibition on multiracial political parties was lifted. He also relaxed the Group Areas Act, which barred non-whites from living in certain areas. In 1988, a new law created "Open Group Areas" or racially mixed neighborhoods. But these neighborhoods had to receive a Government permit, and had to have the support of the local Whites immediately concerned, and had to be a high class neighborhood in the major cities typically in order to receive the permit. In 1983, the above constitutional reforms granted limited political rights to Coloureds and Indians. Botha also became the first South African government leader to authorise contacts with Nelson Mandela, the imprisoned leader of the African National Congress. However, in the face of rising discontent and violence, Botha refused to cede political power to blacks and imposed greater security measures against anti-apartheid activists. Botha also refused to negotiate with the ANC.  In 1985, Botha delivered the Rubicon speech which was a policy address in which he refused to give in to demands by the black population, including the release of Mandela. Botha's defiance of international opinion further isolated South Africa, leading to economic sanctions and a rapid decline in the value of the rand. The following year, when the US introduced the Comprehensive Anti-Apartheid Act, Botha declared a nationwide state of emergency. He is famously quoted during this time as saying, "This uprising will bring out the beast in us".  As economic and diplomatic actions against South Africa increased, civil unrest spread amongst the black population, supported by the ANC and neighbouring black-majority governments. On 16 May 1986, Botha publicly warned neighbouring states against engaging in "unsolicited interference" in South Africa's affairs. Four days later, Botha ordered air strikes against selected targets in Lusaka, Harare, and Gaborone, including the offices of exiled ANC activists. Botha charged that these raids were just a "first installment" and showed that "South Africa has the capacity and the will to break the [African National Congress]."  In spite of the concessions made by Botha, the apartheid years under his leadership were by far the most brutal. Thousands were detained without trial during Botha's presidency, while others were tortured and killed. The Truth and Reconciliation Commission found Botha responsible for gross violations of human rights. He was also found to have directly authorised 'unlawful activity which included killing.' However, Botha refused to apologise for apartheid. In a 2006 interview to mark his 90th birthday, he suggested that he had no regrets about the way he had run the country. He denied, however, that he had ever considered black South Africans to be in any way inferior to whites, but conceded that "some" whites did hold that view. He also claimed that the apartheid policies were inherited from the British colonial administration in the Cape and Natal Province, implying that he considered them something he and his government had followed by default.

Renaissance are an English progressive rock band, best known for their 1978 UK top 10 hit "Northern Lights" and progressive rock classics like "Carpet of the Sun", "Mother Russia", and "Ashes Are Burning". They developed a unique sound, combining a female lead vocal with a fusion of classical, folk, rock, and jazz influences. Characteristic elements of the Renaissance sound are Annie Haslam's wide vocal range, prominent piano accompaniment, orchestral arrangements, vocal harmonies, acoustic guitar, bass guitar, synthesiser, and versatile drum work. The band created a significant following in the northeast United States in the 70s, and that region remains their strongest fan base.
As The Yardbirds were transforming into The New Yardbirds (with Jimmy Page) in 1968 and then Led Zeppelin, departing members Keith Relf and Jim McCarty formed an acoustic duo called Together.  They released "Henry's Coming Home" b/w "Love Mum And Dad" as a single on Columbia Records in November 1968 without chart success.  In January 1969, Relf and McCarty organised a new group devoted to experimentation with rock, folk, and classical forms. In his book Mountains come out of the sky: an illustrated history of prog rock, Will Romano quoted McCarty:  This quintet -- Relf on guitar and vocals, McCarty on drums and vocals, plus bassist Louis Cennamo, pianist John Hawken, and Relf's sister Jane as an additional vocalist -- released a pair of albums on Elektra (US) and Island (UK-ILPS 9112), the first one, titled simply Renaissance, being produced by fellow ex-Yardbird Paul Samwell-Smith.  The band had begun performing in May 1969, before recording had commenced for the debut LP, mostly in the UK, but with occasional forays abroad, including festivals in Belgium (Amougies, October 1969) and France (Operation 666 at the Olympia in January 1970, and Le Bourget in March 1970, both in Paris). In February 1970 they embarked on a North American tour, but that month-long trek proved only marginally successful. Because of their Yardbirds credentials, they found themselves paired with bands such as The Kinks and their new classically oriented direction did not always go down well because audiences were expecting rock/blues-based material.  Beginning in the late spring of 1970 as touring began to grind on them, the original band gradually dissolved. Relf and McCarty decided to quit performing, and Cennamo joined Colosseum. Hawken organised a new line-up to fulfill contractual obligations to Island Records and complete the band's second album, Illusion which had been left unfinished.
