Background: A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra. Some music ensembles consist solely of singers, such as choirs and doo wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers.
Context: Five-piece bands have existed in rock music since the development of the genre. The Beach Boys, The Rolling Stones (until 1993), Aerosmith, Def Leppard, AC/DC, Oasis, Pearl Jam, Guns N' Roses, Radiohead, The Strokes, The Yardbirds, 311 and The Hives are examples of the common vocalist, lead guitar, rhythm guitar, bass, and drums lineup whilst other bands such as Judas Priest have two guitarists who equally share lead and rhythm parts. An alternative to the five-member lineup replaces the rhythm guitarist with a keyboard-synthesizer player (examples being the bands Journey, Elbow, Dream Theater, Genesis, Jethro Tull, The Zombies, The Animals, Bon Jovi, Yes, Fleetwood Mac, Marilyn Manson and Deep Purple, all of which consist of a vocalist, guitarist, bassist, keyboardist, and a drummer) or with a turntablist such as Deftones, Hed PE, Incubus or Limp Bizkit. Alternatives include a keyboardist, guitarist, drummer, bassist, and saxophonist, such as The Sonics, The Dave Clark 5, and Sam the Sham and the Pharaohs. Another alternative is three guitarists, a bassist and a drummer, such as Foo Fighters, Radiohead, and The Byrds. Some five-person bands feature two guitarists, a keyboardist, a bassist and a drummer, with one or more of these musicians (typically one of the guitarists) handling lead vocals on top of their instrument (examples being Children of Bodom, Styx, Sturm und Drang, Relient K, Ensiferum and the current line up of Status Quo). In some cases, typically in cover bands, one musician plays either rhythm guitar or keyboards, depending on the song (one notable band being Firewind, with Bob Katsionis handling this particular role). Other times, the vocalist will bring another musical "voice" to the table, most commonly a harmonica or percussion; Mick Jagger, for example, played harmonica and percussion instruments like maracas and tambourine whilst singing at the same time. Keith Relf of the Yardbirds played harmonica frequently, though not often while also singing. Ozzy Osbourne was also known to play the harmonica on some occasions (i.e. "The Wizard" by Black Sabbath). Vocalist Robert Brown of lesser known steampunk band Abney Park plays harmonica, accordion, and darbuka in addition to mandolin. Flutes are also commonly used by vocalists, most notably Ian Anderson of Jethro Tull and Ray Thomas of the Moody Blues, though these are difficult to play while singing at the same time. A less common lineup is to have lead vocals, two guitarists of varying types and two drummers, e.g. Adam and the Ants.
Question: is the guitar or keyboard appearance dependent on something?
Answer:

Background: Sutcliffe was born in Bingley in the West Riding of Yorkshire to a working-class family. He was given a Catholic upbringing by his parents, John William Sutcliffe and his wife Kathleen Frances (nee Coonan). Reportedly a loner, he left school aged fifteen and had a series of menial jobs, including two stints as a gravedigger in the 1960s. Between November 1971 and April 1973, Sutcliffe worked at the Baird Television factory on a packaging line.
Context: An application by Sutcliffe for a minimum term to be set, offering the possibility of parole after that date if it is thought safe to release him, was heard by the High Court of Justice on 16 July 2010. The High Court decided that Sutcliffe will never be released. Mr Justice Mitting stated: This was a campaign of murder which terrorised the population of a large part of Yorkshire for several years. The only explanation for it, on the jury's verdict, was anger, hatred and obsession. Apart from a terrorist outrage, it is difficult to conceive of circumstances in which one man could account for so many victims. Psychological reports describing his mental state were taken into consideration, as was the severity of his crimes. Barring judicial decisions to the contrary, Sutcliffe will spend the rest of his life in Broadmoor Hospital. On 4 August 2010, a spokeswoman for the Judicial Communications Office confirmed that Sutcliffe had initiated an appeal against the decision. The hearing for Sutcliffe's appeal against the ruling began on 30 November 2010 at the Court of Appeal. It was rejected on 14 January 2011. On 9 March 2011, the Court of Appeal rejected Sutcliffe's application for leave to appeal to the Supreme Court. In December 2015 Sutcliffe was assessed as being "no longer mentally ill". In August 2016, a medical tribunal ruled that he no longer required clinical treatment for his mental condition, and could be returned to prison. Sutcliffe is reported to have been transferred from Broadmoor to Frankland Prison in Durham in August 2016.
Question: Any aspect of the appeal you ind interesting?
Answer:
Psychological reports describing his mental state were taken into consideration, as was the severity of his crimes.
