Problem: Darrell Lance Abbott (August 20, 1966 - December 8, 2004), also known as Dimebag Darrell and Diamond Darrell, was an American musician and songwriter who was a co-founder of Pantera alongside his brother Vinnie Paul, and founder of Damageplan. He was considered to be one of the driving forces behind groove metal. Abbott was shot and killed by a gunman while on stage during a performance with Damageplan on December 8, 2004, at the Alrosa Villa in Columbus, Ohio. He ranked No. 92 in Rolling Stone magazine's 100 Greatest Guitarists and No. 1 in the UK magazine Metal Hammer.

Abbott formed Pantera in 1981 with his brother Vinnie Paul on drums. Originally, he called himself Diamond Darrell Lance. The band was influenced with thrash metal acts such as Slayer, Megadeth, Venom, and Metallica as well as traditional metal bands such as Black Sabbath, Iron Maiden, Motorhead, and Judas Priest. Shortly after singer Phil Anselmo joined Pantera, Darrell was invited by Dave Mustaine to join Megadeth. Darrell was willing to join, but on the condition that Mustaine also hire his brother Vinnie on drums. As Mustaine already had a drummer, Chuck Behler, Darrell decided to stay with Pantera. Pantera would go on to become a key formulator of the post-thrash subgenre of "groove" metal. It would not be until nine years after forming that Pantera saw its first piece of commercial success in its 1990 major label debut, Cowboys from Hell. Pantera's "groove" style came to fruition in its breakthrough album Vulgar Display of Power, released on February 25, 1992, which saw the replacement of the power metal falsetto vocals with a hardcore-influenced shouted delivery and heavier guitar sound. On Pantera's 1994 album Far Beyond Driven, Abbott, who'd been listed on all prior albums under the moniker "Diamond Darrell", was listed as "Dimebag Darrell". On the night before Pantera's live appearance at the Monsters of Rock in England's Donington Park, the Abbott brothers got involved in altercations at a local club with journalists from magazines Kerrang! and Raw. Pantera began to suffer from mounting tensions between band members in the mid-1990s, largely due to vocalist Phil Anselmo's rampant drug abuse. In 2001, the group went on hiatus, during which time Anselmo worked on side projects, such as Superjoint Ritual and Down. This caused more friction within the band, as the Abbott brothers kept waiting for Anselmo to become available to work with them again. The frustration with Anselmo led to their decision to disband Pantera in 2003.

When was the album released?

Background: Terence Joseph "Terry" Nation (8 August 1930 - 9 March 1997) was a Welsh television writer and novelist. Nation first made his name as a comedy writer before becoming a prolific writer for drama, working on many of the most popular British series of the 1960s and 1970s. He made a significant contribution to the long-running BBC science-fiction series Doctor Who from its outset, creating the villainous Daleks which established its early popularity and later devising the recurring character of Davros.
Context: Having returned to writing for Doctor Who, the BBC commissioned Nation to create a new science-fiction drama series. First broadcast in 1975, Survivors is the post-apocalyptic story of the last humans on Earth after the world's population has been devastated by plague. Although the series was well received, Nation's creative vision conflicted with that of producer Terence Dudley, and the final two seasons were produced without Nation's involvement. Meanwhile, screenwriter Brian Clemens claimed that he had related the concept for Survivors to Nation in the late 1960s, having registered it with the Writers' Guild of Great Britain in 1965; Nation denied the allegations. Although the case was ultimately brought before the High Court, both sides withdrew from the proceedings after their legal costs mounted. The production of Nation's next BBC creation, Blake's 7, experienced fewer problems. This series follows a group of criminals and political prisoners who are on the run from the evil "Terran Federation", piloting a stolen spaceship of unknown origin. Running for four seasons from 1978 to 1981, Blake's 7 acquired a worldwide fan following, and proved especially popular in Britain. Although Nation scripted the whole of the first season of Blake's 7, his creative influence subsequently declined in the following two seasons despite writing some key episodes, as script editor Chris Boucher exerted a greater influence on those seasons. Nation didn't write any episodes in the fourth season of Blake's 7. In the 1980s, Nation attempted, without success, to secure funding for a fifth season of Blake's 7. During the 1970s, Nation wrote a children's novel for his daughter Rebecca (after whom he named the character of Rebec in the 1973 Doctor Who serial Planet of the Daleks) titled Rebecca's World: Journey to the Forbidden Planet, as well as a novel based on Survivors.
Question: Who produces it?
Answer: Nation's creative vision conflicted with that of producer Terence Dudley, and the final two seasons were produced without Nation's involvement.

Question:
Ai Kago (Jia Hu Ya Yi , Kago Ai), born February 7, 1988 in Yamatotokada, Nara, Japan, is a Japanese singer, actress, author, and former Guinness World Record holder. Kago began her career at the age of 12 as a member of the idol group Morning Musume. In the same year, she became a founding member of Minimoni.
Throughout the second half of 2010, Kago became unhappy with the direction of her work. Around the same time, she began dating restaurant owner Haruhiko Ando, who acted as an in-between for her agency and herself. Since beginning a relationship with Ando, Kago cancelled several jobs at the last minute, causing her agency to suspend her activities. Despite this, she participated in a live performance and opened a separate blog without permission. Kago parted ways with R&A Promotions in November 2010 despite her contract ending in March 2013. As a response, in 2011, Kazuyuki Ito, president of Mainstream (an associate of R&A Promotions), declared that the agency planned on suing for 100 million yen in damages for contract violations. During that time, Kago's career was also derailed by her personal life. In September 2011, Ando was arrested for alleged extortion and claiming to have connections with the yakuza. In the same month, Kago was rushed to a nearby hospital after agency officials found her on the floor of her apartment with cuts to her wrists. Her life was reported to be not in danger, though there were speculations that it was a planned suicide. Following the incident, she and Ando registered their marriage, and Kago became pregnant. After spending 2012 out of the public eye with the birth of her daughter, Minami, Kago transferred to a new agency in 2013. Planning to revive her music career, she formed an idol group, which was later named Girls Beat!! The group would be crowd-sourced using lyrics, music, and costume ideas submitted by fans. Remi Kita and Ryona Himeno were recruited as the other two members after passing the auditions. Girls Beat!! released their first single, "Sekai Seifuku" on July 22, 2014. Their activities were abruptly put on hold when an arrest warrant was put out for Ando in October on suspicions of loaning money at illegal interest rates. Kago later filed for divorce, planning to continue activities once the divorce was finalized. Although Kago was eventually successful in doing so, in August 2015, her contract with her agency expired, though she continued activities with Girls Beat!! in November. On February 29, 2016, she graduated from the group.
