Background: Kevin Moore (born May 26, 1967) is an American keyboardist, vocalist, composer, and founder of the Chroma Key music project. He is also a former member of the American progressive metal/rock band Dream Theater, co-founder of the progressive rock supergroup O.S.I. and has composed film soundtracks. Throughout his career, he has become known for his emotional music and lyrics, nomadic lifestyle and use of spoken word samples. Moore started his music career in progressive metal band Dream Theater.
Context: Dream Theater's debut studio album was 1989's When Dream and Day Unite, which earned the group comparisons to well-known progressive rock bands such as Rush and Queensryche. Their big breakthrough, however, came in 1992 with the album Images and Words, featuring the band's highest charting single to date, "Pull Me Under". The song, which included lyrics by Moore, reached #10 on the Billboard Mainstream Rock Tracks chart. Following their relentless touring in support of the second album, the band also went on to release a live album, Live at the Marquee, and a video, Images and Words: Live In Tokyo. The video's extensive documentary footage would subsequently introduce many fans to Moore's ironic sense of humor.  In 1994, the band released its third studio album, Awake, which was the band's highest charting album to date with Moore, reaching #32. The album featured Moore's signature song, a haunting piano-driven ballad called "Space-Dye Vest." Shortly before the album was mixed, though, Moore announced to the rest of the band that he wished to concentrate on his own musical interests and would be quitting Dream Theater. According to Portnoy, Moore became interested in the independence of working on his own as opposed to the compromise of a band environment. Although Dream Theater has since invited him to play reunion shows, Moore has said he prefers to move forward as opposed to looking back. He also declined to take part in the official Dream Theater biography titled Lifting Shadows.  During his time in Dream Theater, Moore wrote the lyrics to songs on each of the band's albums and also to some of the band's demos and b-sides. On When Dream and Day Unite, he wrote "Light Fuse and Get Away" and "Only a Matter of Time." On Images and Words, he penned "Pull Me Under", "Surrounded", "Wait for Sleep", and parts of "Take the Time." On Awake, the songs "6:00", "Lie", and "Space-Dye Vest" all featured his lyrics. Demos with his lyrics include "Don't Look Past Me," the final verse of "To Live Forever '94," "A Vision," "Vital Star," and "Two Far."
Question: When did Kevin Moore leave Dream Theater?
Answer: Shortly before the album was mixed, though, Moore announced to the rest of the band that he wished to concentrate on his own musical interests

Background: Nathan Charles Buckley (born 26 July 1972) is a former professional Australian rules football player, commentator and coach, best known for his time as captain of the Collingwood Football Club in the Australian Football League (AFL). He is currently the senior coach of the Collingwood Football Club. He is listed by journalist Mike Sheahan as one of the top 50 players of all time. Buckley won the inaugural Rising Star Award, in 1993, then went on to become one of the game's elite, captaining Collingwood between 1999 and 2007, winning the Norm Smith Medal for best player afield in the 2002 Grand Final despite playing in the losing team, only the third player in history to do so, the Brownlow Medal in 2003, winning Collingwood's Best and Fairest award, the Copeland Trophy, six times and named in the Collingwood Team of the Century.
Context: After months of speculation, Buckley signed a 5-year deal with the Collingwood Football Club. He was the assistant coach for the seasons of 2010 and 2011; he then became head coach in 2012, having taken over from Mick Malthouse, initially signing for a period of three years.  Collingwood began the 2012 season shakily, losing to Hawthorn in round 1 and being thrashed by Carlton in round 3. However they recovered to win their next ten matches and finish the home-and-away season in fourth place with a record of 16-6. They were defeated by Hawthorn in the Qualifying Final before bouncing back to defeat West Coast in the Semi Final. However they lost comfortably to eventual premier Sydney in the Preliminary Final at ANZ Stadium to bring an end to the 2012 season.  2013 started poorly for the Magpies, slumping to a 5-4 record after 9 games. They couldn't quite find the consistency of previous seasons and finished the year in sixth place with a 14-8 record. They played Port Adelaide in their Elimination Final at the MCG and slumped to a shock 24-point loss, which caused Buckley to call into question the club's culture.  Buckley's contract was extended until the end of 2016 by Collingwood in early March 2014, however Collingwood produced a poor performance in round 1 and lost to 2013 grand finalists Fremantle by 70 points. They ended up missing the finals to finish 12th partly due to an injury crisis. Collingwood started the 2015 season at 3-1 as of Round 4 and a gutsy win against Essendon on Anzac Day in 100th centenary of Gallipoli landing.  At the end of Collingwood's 2017 season on 28 August 2017, Buckley was given a two-year contract extension by the club after it undertook a review of the entire football club.
