Background: Eddie James "Son" House, Jr. (March 21, 1902 - October 19, 1988) was an American delta blues singer and guitarist, noted for his highly emotional style of singing and slide guitar playing. After years of hostility to secular music, as a preacher and for a few years also as a church pastor, he turned to blues performance at the age of 25. He quickly developed a unique style by applying the rhythmic drive, vocal power and emotional intensity of his preaching to the newly learned idiom. In a short career interrupted by a spell in Parchman Farm penitentiary, he developed to the point that Charley Patton, the foremost blues artist of the Mississippi Delta region, invited him to share engagements and to accompany him to a 1930 recording session for Paramount Records.
Context: House was born in the hamlet of Lyon, north of Clarksdale, Mississippi, the second of three brothers, and lived in the rural Mississippi Delta until his parents separated, when he was about seven or eight years old. His father, Eddie House, Sr., was a musician, playing the tuba in a band with his brothers and sometimes playing the guitar. He was a church member but also a drinker; he left the church for a time, on account of his drinking, but then gave up alcohol and became a Baptist deacon. Young Eddie House adopted the family commitment to religion and churchgoing. He also absorbed the family love of music but confined himself to singing, showing no interest in the family instrumental band, and hostile to the blues on religious grounds.  When House's parents separated, his mother took him to Tallulah, Louisiana, across the Mississippi River from Vicksburg, Mississippi. When he was in his early teens, they moved to Algiers, New Orleans. Recalling these years, he would later speak of his hatred of blues and his passion for churchgoing (he described himself as "churchy" and "churchified"). At fifteen, probably while living in Algiers, he began preaching sermons.  At the age of nineteen, while living in the Delta, he married Carrie Martin, an older woman from New Orleans. This was a significant step for House; he married in church and against family opposition. The couple moved to her hometown of Centerville, Louisiana, to help run her father's farm. After a couple of years, feeling used and disillusioned, House recalled, "I left her hanging on the gatepost, with her father tellin' me to come back so we could plow some more." Around the same time, probably 1922, House's mother died. In later years, he was still angry about his marriage and said of Carrie, "She wasn't nothin' but one of them New Orleans whores".  House's resentment of farming extended to the many menial jobs he took as a young adult. He moved frequently, on one occasion taking off to East Saint Louis to work in a steel plant. The one job he enjoyed was on a Louisiana horse ranch, which later he celebrated by wearing a cowboy hat in his performances. He found an escape from manual labor when, following a conversion experience ("getting religion") in his early twenties, he was accepted as a paid pastor, first in the Baptist Church and then in the Colored Methodist Episcopal Church. However, he fell into habits which conflicted with his calling--drinking like his father and probably also womanizing. This led him after several years of conflict to leave the church, ceasing his full-time commitment, although he continued to preach sermons from time to time.
Question: Did he work at anything besides playing music?
Answer: in his early twenties, he was accepted as a paid pastor, first in the Baptist Church and then in the Colored Methodist Episcopal Church.

Problem: 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 1987, Cage completed a piece called Two, for flute and piano, dedicated to performers Roberto Fabbriciani and Carlo Neri. The title referred to the number of performers needed; the music consisted of short notated fragments to be played at any tempo within the indicated time constraints. Cage went on to write some forty such pieces, one of the last being Eighty (1992, premiered in Munich on 28 October 2011), usually employing a variant of the same technique; together, these works are known as Number Pieces. The process of composition, in many of the later Number Pieces, was simple selection of pitch range and pitches from that range, using chance procedures; the music has been linked to Cage's anarchic leanings. One11 (i.e. the eleventh piece for a single performer), completed in early 1992, was Cage's first and only foray into film.  Another new direction, also taken in 1987, was opera: Cage produced five operas, all sharing the same title Europera, in 1987-91. Europeras I and II require greater forces than III, IV and V, which are on a chamber scale.  Already in the course of the 1980s, Cage's health worsened progressively: he suffered not only from arthritis, but also from sciatica and arteriosclerosis. He suffered a stroke that left the movement of his left leg restricted, and, in 1985, broke an arm. During this time, Cage pursued a macrobiotic diet. Nevertheless, ever since arthritis started plaguing him, the composer was aware of his age, and, as biographer David Revill observed, "the fire which he began to incorporate in his visual work in 1985 is not only the fire he has set aside for so long--the fire of passion--but also fire as transitoriness and fragility." On August 11, 1992, while preparing evening tea for himself and Cunningham, Cage suffered another stroke. He was taken to St. Vincent's Hospital in Manhattan, where he died on the morning of August 12. He was 79.  According to his wishes, Cage's body was cremated, and the ashes scattered in the Ramapo Mountains, near Stony Point, New York, the same place where Cage scattered the ashes of his parents, years before. The composer's death occurred only weeks before a celebration of his 80th birthday organized in Frankfurt by the composer Walter Zimmermann and the musicologist Stefan Schaedler was due to take place. The event went ahead as planned, including a performance of the Concert for Piano and Orchestra by David Tudor and Ensemble Modern. Merce Cunningham lived another 17 years, dying of natural causes in July 2009.
Question: did he work with other musicians?
Answer:
In 1987, Cage completed a piece called Two, for flute and piano, dedicated to performers Roberto Fabbriciani and Carlo Neri.
