Background: Nicholas Edward Cave  (born 22 September 1957) is an Australian musician, singer-songwriter, author, screenwriter, composer and occasional film actor, best known as the frontman of the rock band Nick Cave and the Bad Seeds. Cave's music is generally characterised by emotional intensity, a wide variety of influences, and lyrical obsessions with death, religion, love and violence. Born and raised in rural Victoria, Cave studied art before turning to music in the 1970s. As frontman of the Boys Next Door (later renamed the Birthday Party), he became a central figure in Melbourne's burgeoning post-punk scene.
Context: Cave was born on 22 September 1957 in Warracknabeal, a small country town in the state of Victoria, Australia, to Dawn Cave (nee Treadwell) and Colin Frank Cave. As a child, he lived in Warracknabeal and then Wangaratta in rural Victoria. His father taught English and mathematics at the local technical school; his mother was a librarian at the high school that Nick attended. Cave's father introduced him to literary classics from an early age, such as Crime and Punishment and Lolita, and also organised the first symposium on the Australian bushranger and outlaw Ned Kelly, with whom Nick was enamoured as a child.  When Cave was 9 he joined the choir of Wangaratta's Holy Trinity Cathedral. At 13 he was expelled from Wangaratta High School. In 1970, having moved with his family to the Melbourne suburb of Murrumbeena, he became a boarder and later day student at Caulfield Grammar School. He was 19 when his father was killed in a car accident; his mother told him of his father's death while she was bailing him out of a St Kilda police station where he was being held on a charge of burglary. He would later recall that his father "died at a point in my life when I was most confused" and that "the loss of my father created in my life a vacuum, a space in which my words began to float and collect and find their purpose".  After his secondary schooling, Cave studied painting at the Caulfield Institute of Technology in 1976, but dropped out the following year to pursue music. He also began using heroin around the time that he left art school.  Cave attended his first music concert at Melbourne's Festival Hall. The bill consisted of Manfred Mann, Deep Purple and Free. Cave recalled: "I remember sitting there and feeling physically the sound going through me."

Question:
Jonas Edward Salk (; October 28, 1914 - June 23, 1995) was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines. Born in New York City, he attended New York University School of Medicine, later choosing to do medical research instead of becoming a practicing physician. In 1939, after earning his medical degree, Salk began an internship as a physician scientist at Mount Sinai Hospital.
In 1947, Salk became ambitious for his own lab and was granted one at the University of Pittsburgh, but the lab was smaller than he had hoped and he found the rules imposed by the university restrictive. In 1948, Harry Weaver, the director of research at the National Foundation for Infantile Paralysis, contacted Salk. He asked Salk to find out if there were more types of polio than the three then known, offering additional space, equipment and researchers. For the first year he gathered supplies and researchers including Julius Youngner, Byron Bennett, L. James Lewis, and secretary Lorraine Friedman joined Salk's team, as well. As time went on, Salk began securing grants from the Mellon family and was able to build a working virology laboratory. He later joined the National Foundation for Infantile Paralysis's polio project established by President Franklin D. Roosevelt.  Extensive publicity and fear of polio led to much increased funding, $67 million by 1955, but research continued on dangerous live vaccines. Salk decided to use the safer 'killed' virus, instead of weakened forms of strains of polio viruses like the ones used contemporarily by Albert Sabin, who was developing an oral vaccine. After successful tests on laboratory animals, on July 2, 1952, assisted by the staff at the D.T. Watson Home for Crippled Children, Salk injected 43 children with his killed-virus vaccine. A few weeks later, Salk injected children at the Polk State School for the retarded and feeble-minded. In 1954 he tested the vaccine on about one million children, known as the polio pioneers. The vaccine was announced as safe on April 12, 1955.  The project became large, involving 100 million contributors to the March of Dimes, and 7 million volunteers. The foundation allowed itself to go into debt to finance the final research required to develop the Salk vaccine. Salk worked incessantly for two and a half years.  Salk's inactivated polio vaccine was the first vaccine for the disease; it came into use in 1955. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.

Problem: Background: Sergio Santos Mendes (Portuguese pronunciation: ['seRZju 'satuZ 'medZiS]; born February 11, 1941) is a Brazilian musician. He has over 55 releases, and plays bossa nova heavily crossed with jazz and funk. He was nominated for an Academy Award for Best Original Song in 2012 as co-writer of the song "Real in Rio" from the animated film Rio. Mendes is married to Gracinha Leporace, who has performed with him since the early 1970s.
Context: Mendes' career in the U.S. stalled in the mid-1970s, but he remained very popular in South America and Japan. His two albums with Bell Records in 1973 and 1974 followed by several for Elektra from 1975 on, found Mendes continuing to mine the best in American pop music and post-Bossa writers of his native Brazil, while forging new directions in soul with collaborators like Stevie Wonder, who wrote Mendes' R&B-inflected minor hit, "The Real Thing."  In 1983, he rejoined Alpert's A&M records and enjoyed huge success with a self-titled album and several follow-up albums, all of which received considerable adult contemporary airplay with charting singles. "Never Gonna Let You Go", featuring vocals by Joe Pizzulo and Leza Miller, equalled the success of his 1968 single "The Look of Love" by reaching No. 4 on the Billboard Hot 100 chart; it also spent four weeks atop the Billboard adult contemporary chart. In 1984 he recorded the Confetti album, which had the hit songs "Olympia", which was also used as a theme song for the Olympic games that year and "Alibis". The '80s also found Mendes working with singer Lani Hall again on the song "No Place to Hide" from the Brasil '86 album, and as producer of her vocals on the title song for the James Bond film Never Say Never Again.  By the time Mendes released his Grammy-winning Elektra album Brasileiro in 1992, he was the undisputed master of pop-inflected Brazilian jazz. The late-1990s lounge music revival brought retrospection and respect to Mendes' oeuvre, particularly the classic Brasil '66 albums.
Question: What was the name of one of the albums?
Answer:
while forging new directions in soul with collaborators like Stevie Wonder, who wrote Mendes' R&B-inflected minor hit, "The Real Thing."
