Problem: Background: Zenzile Miriam Makeba (4 March 1932 - 9 November 2008), nicknamed Mama Africa, was a South African singer, actress, United Nations goodwill ambassador, and civil-rights activist. Associated with musical genres including Afropop, jazz, and world music, she was an advocate against apartheid and white-minority government in South Africa. Born in Johannesburg to Swazi and Xhosa parents, Makeba was forced to find employment as a child after the death of her father. She had a brief and allegedly abusive first marriage at the age of 17, gave birth to her only child in 1950, and survived breast cancer.
Context: Following growing pressure from the anti-apartheid movement both domestically and internationally, in 1990 State President Frederik Willem de Klerk reversed the ban on the African National Congress and other anti-apartheid organisations, and announced that Mandela would shortly be released from prison. Mandela was released in February 1990. He persuaded Makeba to return to South Africa, which she did, using her French passport, on 10 June 1990.  Makeba, Gillespie, Simone, and Masekela recorded and released her studio album, Eyes on Tomorrow, in 1991. It combined jazz, R&B, pop, and traditional African music, and was a hit across Africa. Makeba and Gillespie then toured the world together to promote it. In November she made a guest appearance on a US sitcom, The Cosby Show. In 1992, she starred in the film Sarafina!, which centred on students involved in the 1976 Soweto uprising. Makeba portrayed the title character's mother, Angelina, a role which The New York Times described as having been performed with "immense dignity".  On 16 October 1999, Makeba was named a Goodwill Ambassador of the Food and Agriculture Organization of the United Nations. In January 2000, her album, Homeland, produced by the New York City based record label Putumayo World Music, was nominated for a Grammy Award in the Best World Music Album category. She worked closely with Graca Machel-Mandela, the South African first lady, advocating for children suffering from HIV/AIDS, child soldiers, and the physically handicapped. She established the Makeba Centre for Girls, a home for orphans, described in an obituary as her most personal project. She also took part in the 2002 documentary Amandla!: A Revolution in Four-Part Harmony, which examined the struggles of black South Africans against apartheid through the music of the period. Makeba's second autobiography, Makeba: The Miriam Makeba Story, was published in 2004. In 2005 she announced that she would retire and began a farewell tour, but despite having osteoarthritis, continued to perform until her death. During this period, her grandchildren Nelson Lumumba Lee and Zenzi Lee, and her great-grandchild Lindelani, occasionally joined her performances.  On 9 November 2008, Makeba fell ill during a concert in Castel Volturno, near Caserta, Italy. The concert had been organised to support the writer Roberto Saviano in his stand against the Camorra, a criminal organisation active in the Campania region. She suffered a heart attack after singing her hit song "Pata Pata", and was taken to the Pineta Grande clinic, where doctors were unable to revive her.
Question: What did Makeba do upon her return to South Africa?
Answer: Makeba, Gillespie, Simone, and Masekela recorded and released her studio album,

Background: The Birthday Party (originally known as The Boys Next Door) were an Australian post-punk band, active from 1978 to 1983. Despite limited commercial success, The Birthday Party's influence has been far-reaching, and they have been called "one of the darkest and most challenging post-punk groups to emerge in the early '80s." The group's "bleak and noisy soundscapes," which drew irreverently on blues, free jazz, and rockabilly, provided the setting for vocalist Nick Cave's disturbing tales of violence and perversion. Their music has been described by critic Simon Reynolds as gothic, and their single "Release the Bats" was particularly influential on the emerging gothic scene.
Context: The Boys Next Door's best known song, "Shivers", written by Howard, and first performed and recorded by his band The Young Charlatans, was banned by radio stations because of a reference to suicide. After recordings and moderate success in Australia (including hundreds of live shows) they headed for London in 1980, changed their name to The Birthday Party and launched into a period of innovative and aggressive music-making. Some sources say the band took its new name from the Harold Pinter play The Birthday Party; others (including Ian Johnston's Cave biography) state it was prompted by Cave misremembering, or intentionally misattributing, the name to a non-existent birthday party scene in the Dostoyevsky novel Crime and Punishment. In a 2008 interview, Rowland S. Howard gave his own recollection: "The name The Birthday Party came up in conversation between Nick and myself. There's this apocryphal story about it coming from a Dostoyevsky novel. It may have had various connotations, but what he and I spoke about was a sense of celebration and making things into more an occasion and ritual". They resided in London, with trips back to Australia and tours through Europe and the U.S. before relocating to West Berlin in 1982.  Above the barely-controlled racket, Cave's vocals ranged from desperate to simply menacing and demented. Critics have written that "neither John Cale nor Alfred Hitchcock was ever this scary," and that Cave "doesn't so much sing his vocals as expel them from his gut". Though Cave drew on earlier rock and roll shriekers--especially Iggy Pop and Suicide's Alan Vega--his singing with the Birthday Party remains powerful and distinct. His lyrics also drew on Arthur Rimbaud and Charles Baudelaire.  The single "Release the Bats" came out during the emergence of the gothic scene. This song about "vampire sex" was promoted by an advertisement with the words "Dirtiness is next to antigodliness".  Their 1982 album Junkyard was inspired by American Southern Gothic imagery, dealing with extreme subjects like an evangelist's murdered daughter.
Question: did their style change over time?
Answer:
his singing with the Birthday Party remains powerful and distinct.
