[Q]: Context: John Graham Mellor (21 August 1952  22 December 2002), known by his stage name Joe Strummer, was a British musician, singer, actor and songwriter who was the co-founder, lyricist, rhythm guitarist and lead vocalist of the Clash, a punk rock band that was formed in 1976 as part of the original wave of British punk. Their music also incorporated elements of reggae, ska, dub, funk, rap, and rockabilly. The Clash were one of the most prominent of the emerging bands in the UK punk rock scene, with their second album, "Give 'Em Enough Rope" (1978) reaching number 2 on the UK charts. Soon after, they began achieving success in the US, starting with "London Calling" (1979), and peaking with 1982's "Combat Rock", reaching number 7 on the US charts and being certified 2× platinum there. The Clash's politicised lyrics, musical experimentation, and rebellious attitude had a far-reaching influence on rock, and alternative rock in particular., A record producer or music producer oversees and manages the sound recording and production of a band or performer's music, which may range from recording one song to recording a lengthy concept album. A producer has many roles during the recording process. The roles of a producer vary. He or she may gather musical ideas for the project, collaborate with the artists to select cover tunes or original songs by the artist/group, work with artists and help them to improve their songs, lyrics or arrangements. , Funk is a music genre that originated in the mid- 1960s when African American musicians created a rhythmic, danceable new form of music through a mixture of soul music, jazz, and rhythm and blues (R&B). Funk de-emphasizes melody and chord progressions used in other related genres and brings a strong rhythmic groove of a bass line played by an electric bassist and a drum part played by a drummer to the foreground. Funk songs are often based on an extended vamp on a single chord, distinguishing them from R&B and soul songs, which are built on complex chord progressions. Funk uses the same richly-colored extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, or dominant seventh chords with altered ninths., Music is an art form and cultural activity whose medium is sound and silence, which exist in time. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek  ("mousike"; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound.", Scott Shields ( born 26 November 1969 , Glasgow ) is a Scottish musician and record producer , best known as a member of Joe Strummer 's backing band The Mescaleros ., Reggae is a music genre that originated in Jamaica in the late 1960s. The term also denotes the modern popular music of Jamaica and its diaspora. A 1968 single by Toots and the Maytals "Do the Reggay" was the first popular song to use the word "reggae," effectively naming the genre and introducing it to a global audience. While sometimes used in a broad sense to refer to most types of popular Jamaican dance music, the term "reggae" more properly denotes a particular music style that was strongly influenced by traditional mento as well as American jazz and rhythm and blues, especially the New Orleans R&B practiced by Fats Domino and Allen Toussaint, and evolved out of the earlier genres ska and rocksteady. Reggae usually relates news, social gossip, and political comment. Reggae spread into a commercialized jazz field, being known first as Rudie Blues, then Ska, later Blue Beat, and Rock Steady. It is instantly recognizable from the counterpoint between the bass and drum downbeat, and the offbeat rhythm section. The immediate origins of reggae were in ska and rock steady; from the latter, reggae took over the use of the bass as a percussion instrument., Punk rock (or simply "punk") is a rock music genre that developed in the early to mid 1970s in the United States, United Kingdom, and Australia. Rooted in 1960s garage rock and other forms of what is now known as "proto-punk" music, punk rock bands rejected perceived excesses of mainstream 1970s rock. Punk bands typically use short or fast-paced songs, with hard-edged melodies and singing styles, stripped-down instrumentation, and often political, anti-establishment lyrics. Punk embraces a DIY ethic; many bands self-produce recordings and distribute them through informal channels., A song, most broadly, is a single (and often standalone) work of music that is typically intended to be sung by the human voice with distinct and fixed pitches and patterns using sound and silence and a variety of forms that often include the repetition of sections. Written words created specifically for music or for which music is specifically created, are called lyrics. If a pre-existing poem is set to composed music in classical music it is an art song. Songs that are sung on repeated pitches without distinct contours and patterns that rise and fall are called chants. Songs in a simple style that are learned informally are often referred to as folk songs. Songs that are composed for professional singers who sell their recordings or live shows to the mass market are called popular songs. These songs, which have broad appeal, are often composed by professional songwriters, composers and lyricists. Art songs are composed by trained classical composers for concert or recital performances. Songs are performed live and recorded on audio or video (or in some, cases, a song may be performed live and simultaneously recorded). Songs may also appear in plays, musical theatre, stage shows of any form, and within operas., Ska (Jamaican ) is a music genre that originated in Jamaica in the late 1950s and was the precursor to rocksteady and reggae. Ska combined elements of Caribbean mento and calypso with American jazz and rhythm and blues. It is characterized by a walking bass line accented with rhythms on the off-beat. Ska developed in Jamaica in the 1960s when Prince Buster, Clement "Coxsone" Dodd, and Duke Reid formed sound systems to play American rhythm & blues and then began recording their own songs. Some suggest ska dates to earlier times, however. In the early 1960s, ska was the dominant music genre of Jamaica and was popular with British mods. Later it became popular with many skinheads., The Clash were an English punk rock band that formed in 1976 as part of the original wave of British punk. Along with punk, their music incorporated elements of reggae, dub, funk, ska and rockabilly. For most of their recording career the Clash consisted of Joe Strummer (lead vocals, rhythm guitar), Mick Jones (lead guitar, lead vocals), Paul Simonon (bass guitar, vocals) and Nicky "Topper" Headon (drums, percussion). Headon left the group in 1982, and internal friction led to Jones's departure the following year. The group continued with new members, but finally disbanded in early 1986., Subject: scott shields , Relation: instrument, Options: (A) bass (B) bass guitar (C) guitar (D) human voice (E) percussion instrument (F) singing
