Question:
Heitor Villa-Lobos (Portuguese: [ej,toR ,vila 'lobus]; March 5, 1887 - November 17, 1959) was a Brazilian composer, described as "the single most significant creative figure in 20th-century Brazilian art music". Villa-Lobos has become the best-known South American composer of all time. A prolific composer, he wrote numerous orchestral, chamber, instrumental and vocal works, totaling over 2000 works by his death in 1959. His music was influenced by both Brazilian folk music and by stylistic elements from the European classical tradition, as exemplified by his Bachianas Brasileiras (Brazilian Bachian-pieces).
Heitor Villa-Lobos was born in Rio de Janeiro. His father, Raul, was a civil servant, an educated man of Spanish extraction, a librarian, and an amateur astronomer and musician. In Villa-Lobos's early childhood, Brazil underwent a period of social revolution and modernisation, abolishing slavery in 1888 and overthrowing the Empire of Brazil in 1889. The changes in Brazil were reflected in its musical life: previously European music had been the dominant influence, and the courses at the Conservatorio de Musica were grounded in traditional counterpoint and harmony. Villa-Lobos underwent very little of this formal training. After a few abortive harmony lessons, he learnt music by illicit observation from the top of the stairs of the regular musical evenings at his house arranged by his father. He learned to play cello, guitar and clarinet. When his father died suddenly in 1899 he earned a living for his family by playing in cinema and theatre orchestras in Rio.  Around 1905 Villa-Lobos started explorations of Brazil's "dark interior", absorbing the native Brazilian musical culture. Serious doubt has been cast on some of Villa-Lobos's tales of the decade or so he spent on these expeditions, and about his capture and near escape from cannibals, with some believing them to be fabrications or wildly embellished romanticism. After this period, he gave up any idea of conventional training and instead absorbed the musical influences of Brazil's indigenous cultures, themselves based on Portuguese and African, as well as American Indian elements. His earliest compositions were the result of improvisations on the guitar from this period.  Villa-Lobos played with many local Brazilian street-music bands; he was also influenced by the cinema and Ernesto Nazareth's improvised tangos and polkas. For a time Villa-Lobos became a cellist in a Rio opera company, and his early compositions include attempts at Grand Opera. Encouraged by Arthur Napoleao, a pianist and music publisher, he decided to compose seriously.

Question:
Simon & Garfunkel were an American folk rock duo consisting of singer-songwriter Paul Simon and singer Art Garfunkel. They were one of the best-selling music groups of the 1960s and became counterculture icons of the decade's social revolution, alongside artists such as the Beatles, the Beach Boys, and Bob Dylan. Their biggest hits--including "The Sound of Silence" (1964), "Mrs. Robinson" (1968), "The Boxer" (1969), and "Bridge over Troubled Water" (1970)--reached number one on singles charts worldwide. Their often rocky relationship led to artistic disagreements, which resulted in their breakup in 1970.
Wednesday Morning, 3 A.M. sold only 3,000 copies upon its October release, and its poor sales led Simon to move to England where he had previously visited and played some gigs. He toured the small folk clubs, appearing on the same bill and befriending British folk artists such as Bert Jansch, Martin Carthy, Al Stewart, and Sandy Denny. He met Kathy Chitty, who became the object of his affection and is the Kathy in "Kathy's Song" and "America".  A small music publishing company, Lorna Music, licensed "Carlos Dominguez", a single Simon had cut two years prior as "Paul Kane", for a cover by Val Doonican that sold very well. Simon visited Lorna to thank them, and the meeting resulted in a publishing and recording contract. He signed to the Oriole label and released "He Was My Brother" as a single. Simon invited Garfunkel to stay for the summer of 1964. Near the end of the season, Garfunkel returned to Columbia for class, and Simon surprised his friends by saying that he would be returning to the States as well. He would resume his studies at Brooklyn Law School for one semester, partially at his parents' insistence. He returned to England in January 1965, now certain that music was his calling. In the meantime, his landlord, Judith Piepe, had compiled a tape from his work at Lorna and sent it to the BBC in hopes they would play it. The demos aired on the Five to Ten morning show, and were instantly successful. Oriole had folded into CBS by that point, and hoped to record a new Paul Simon album. The Paul Simon Songbook was recorded in June 1965 and featured multiple future Simon & Garfunkel staples, among them "I Am a Rock" and "April Come She Will". CBS flew Wilson over to produce the record, and he stayed at Simon's flat. The album saw release in August, and although sales were poor, Simon felt content with his future in England.  Meanwhile, in the United States, a late-night disc jockey at WBZ-FM in Boston played "The Sound of Silence", where it was popular with a college audience. It was picked up the next day along the East Coast of the United States, down to Cocoa Beach, Florida. Wilson, inspired by the folk rock sound of the Byrds' cover of "Turn! Turn! Turn!" and Dylan's "Like a Rolling Stone", created a rock remix of the song using studio musicians. The remix of "The Sound of Silence" was issued in September 1965, where it reached the Billboard Hot 100. Wilson had not informed the duo of his intention to remix the track; as such, Simon was "horrified" when he first heard it. Garfunkel graduated in 1965, returning to Columbia University to do a master's degree in mathematics.
