Problem: Background: Norman Clifford Louis O'Neill OAM (19 February 1937 - 3 March 2008) was a cricketer who played for New South Wales and Australia. A right-handed batsman known for his back foot strokeplay, O'Neill made his state debut aged 18, before progressing to Test selection aged 21 in late 1958. Early in his career, O'Neill was one of the foremost batsmen in the Australian team, scoring three Test centuries and topping the run scoring aggregates on a 1959-60 tour of the Indian subcontinent which helped Australia win its last Test and series on Pakistani soil for 39 years, as well as another series in India. His career peaked in 1960-61 when he scored 181 in the Tied Test against the West Indies, and at the end of the series, had a career average of 58.25.
Context: Standing six feet tall, O'Neill was compared to Don Bradman upon his entry into Test cricket. At his best, he was a dynamic stroke maker who was a crowd favourite because of his ability to score at a high pace, in particular with his power off the back foot. He was noted for his nimble footwork, which he used to negate spin bowling; however this slowed in his later career as he put on weight. O'Neill particularly liked to sweep the slower bowlers. He often put too much emphasis on his right hand, allowing a large space between his hands on the bat handle, and then turning his right shoulder too square towards the bowler. The renowned English batsman and captain Wally Hammond said that O'Neill was the best all-round batsman he had seen since World War II. O'Neill's tall build, strength and good looks also drew comparison to his boyhood idol Keith Miller. Despite the comparisons to Bradman, O'Neill was much taller and broader, and was often impetuous whereas Bradman was known for his patience and lack of rashness. O'Neill was also criticised for hitting across the line early in his innings. O'Neill was highly regarded for his style and entertainment values. Teammate Alan Davidson said "once set he was the most exhilarating player you'd ever want to see--he was dynamite. He'd play attacking shots off balls other people would only think of defending. He had wonderful skill and technique. His shots off the back foot down the ground off fast bowlers--you can't really describe how good they were." His captain for Australia and New South Wales, Richie Benaud said that he was "one of the greatest entertainers we've had in Australian cricket". O'Neill's style led the British writer EW Swanton to say "the art of batting, he reminded us, was not dead, merely inexplicably dormant" Wisden opined that "A high innings by O'Neill is a thing of masterful beauty. His stroking is delectable, immense in its power." Later in his career, O'Neill became a nervous and superstitious batsman, particular at the start of an innings. He wrote "batting is a lonely business" in his 1964 autobiography Ins and Outs, opining that he sometimes found first-class cricket to be "depressing and lonely". He was regarded as an excellent fieldsman at cover, with a powerful and accurate throw, described by Wisden as a "dream throw" honed from a junior career as a baseballer. He was named as utility player in the 1957 All Australian baseball team, and his ability was such that he was approached by Major League Baseball scouts. Before the retirement of Neil Harvey, he and O'Neill fielded in tandem in the covers and the pair were regarded as the finest fielding combination of the time.
Question: How long did his career last?
Answer:

Background: Kevin Patrick Shields was born on 21 May 1963 in Jamaica Hospital in Queens, New York City, United States. He is the eldest of five siblings born to Irish parents; his mother was a nurse and his father was an executive in the food industry. Shields' parents had emigrated to the United States from Ireland in the 1950s, when the couple were teenagers. Shields attended Christ the King, a Roman Catholic primary school which he described as "a really horrible school run by psychopathic nuns".
Context: Shields' guitar sound has been cited as one of the most recognisable aspects of My Bloody Valentine's music. His sound uses "texture more than technique to create vivid soundscapes". He has been listed at number 95 and 2 on Rolling Stone's and Spin's 100 Greatest Guitarists of All Time list. During the late 1980s, Shields began customising the tremolo systems for his Fender Jaguars and Jazzmaster guitars; he extended the tremolo arm and loosened it considerably, to allow him to manipulate the arm while strumming chords, which resulted in significant pitch bending. Shields used a number of alternate and open tunings that together with his tremolo manipulation, according to Rolling Stone's Michael Azerrad, achieved "a strange warping effect that makes the music wander in and out of focus". Among Shields' notable effects is digital reverse reverb, sourced from a Yamaha SPX90 effects unit. Together with the tremolo manipulation and distortion, he created a technique known as "glide guitar". Shields effects rig, which is composed largely of distortion, graphic equalisers and tone controls, consists of at least 30 effects pedals. His rig is connected to a large number of amplifiers which are often set to maximum volume to increase sustain. During live performances with My Bloody Valentine - particularly during the closing "You Made Me Realise" - Shields creates a blend of noise and excessive feedback, known as "the holocaust", which has often lasted for half an hour and often reached 130db. "It was so loud it was like sensory deprivation," he remarked. "We just liked the fact that we could see a change in the audience at a certain point." Shields' sound and performance have been regarded as influential, with musicians including Billy Corgan and J Mascis citing him as an influence. "Kevin Shields achieved something on Loveless that only the great guitarists achieve: he achieved a wholeness and a unity," observed Living Colour's Vernon Reid. "He created his own sound."
