Problem: Background: Edward de Vere, 17th Earl of Oxford (; 12 April 1550 - 24 June 1604) was an English peer and courtier of the Elizabethan era. Oxford was heir to the second oldest earldom in the kingdom, a court favourite for a time, a sought-after patron of the arts, and noted by his contemporaries as a lyric poet and court playwright, but his reckless and volatile temperament precluded him from attaining any courtly or governmental responsibility and contributed to the dissipation of his estate. Since the 1920s he has been among the most popular alternative candidates proposed for the authorship of Shakespeare's works.
Context: De Vere was born heir to the second oldest earldom in England at the de Vere ancestral home, Hedingham Castle, in Essex, north-east of London. He was the only son of John de Vere, 16th Earl of Oxford, and his second wife, Margery Golding. He was probably named to honour Edward VI, from whom he received a gilded christening cup. He had an older half-sister, Katherine, the child of his father's first marriage to Dorothy Neville, and a younger sister, Mary de Vere. Both his parents had established court connections: the 16th Earl accompanying Princess Elizabeth from house arrest at Hatfield to the throne, and the countess being appointed a maid of honour in 1559.  De Vere was styled Viscount Bulbeck and raised in the Protestant reformed faith. Like many children of the nobility, he was raised by surrogate parents, in his case in the household of Sir Thomas Smith. At eight he entered Queens' College, Cambridge, as an impubes, or immature fellow-commoner, later transferring to St John's. Thomas Fowle, a former fellow of St John's College, Cambridge, was paid PS10 annually as de Vere's tutor.  His father died on 3 August 1562, shortly after making his will. Because he held lands from the Crown by knight service, his son became a royal ward of the Queen and was placed in the household of Sir William Cecil, her secretary of state and chief advisor. At 12, de Vere had become the 17th Earl of Oxford, Lord Great Chamberlain of England, and heir to an estate whose annual income, though assessed at approximately PS2,500, may have run as high as PS3,500 (PS1.08 million as of 2018).

Background: John Milton Cage Jr. (September 5, 1912 - August 12, 1992) was an American composer and music theorist. A pioneer of indeterminacy in music, electroacoustic music, and non-standard use of musical instruments, Cage was one of the leading figures of the post-war avant-garde. Critics have lauded him as one of the most influential composers of the 20th century. He was also instrumental in the development of modern dance, mostly through his association with choreographer Merce Cunningham, who was also Cage's romantic partner for most of their lives.
Context: In 2012, amongst a wide range of American and international centennial celebrations, an eight-day festival was held in Washington DC, with venues found notably more amongst the city's art museums and universities than performance spaces. Earlier in the centennial year, conductor Michael Tilson Thomas presented Cage's Song Books with the San Francisco Symphony at Carnegie Hall in New York. Another celebration came, for instance, in Darmstadt, Germany, which in July 2012 renamed its central station the John Cage Railway Station during the term of its annual new-music courses. At the Ruhrtriennale in Germany, Heiner Goebbels staged a production of Europeras 1 & 2 in a 36,000 sq ft converted factory and commissioned a production of Lecture on Nothing created and performed by Robert Wilson. Jacaranda Music had four concerts planned in Santa Monica, California, for the centennial week. John Cage Day was the name given to several events held during 2012 to mark the centenary of his birth.  A 2012 project was curated by Juraj Kojs to celebrate the centenary of Cage's birth, titled On Silence: Homage to Cage. It consisted of 13 commissioned works created by composers from around the global such as Kasia Glowicka, Adrian Knight and Henry Vega, each being 4 minutes and 33 seconds long in honor of Cage's famous 1952 opus, 4'33''. The program was supported by the Foundation for Emerging Technologies and Arts, Laura Kuhn and the John Cage Trust.  In a homage to Cage's dance work, the Bill T. Jones/Arnie Zane Dance Company in July 2012 "performed an engrossing piece called 'Story/Time'. It was modeled on Cage's 1958 work 'Indeterminacy', in which [Cage and then Jones, respectively,] sat alone onstage, reading aloud ... series of one-minute stories [they]'d written. Dancers from Jones's company performed as [Jones] read."
