Question: Information:  - Ian Kevin Curtis (15 July 1956  18 May 1980) was an English singer-songwriter and musician. He is best known as the lead singer and lyricist of the post-punk band Joy Division. Joy Division released their debut album, "Unknown Pleasures", in 1979 and recorded their follow-up, "Closer", in 1980.  - Dance music is music composed specifically to facilitate or accompany dancing. It can be either a whole musical piece or part of a larger musical arrangement. In terms of performance, the major categories are live dance music and recorded dance music. While there exist attestations of the combination of dance and music in ancient times (for example Ancient Greek vases sometimes show dancers accompanied by musicians), the earliest Western dance music that we can still reproduce with a degree of certainty are the surviving medieval dances. In the Baroque period, the major dance styles were noble court dances (see Baroque dance). In the classical music era, the minuet was frequently used as a third movement, although in this context it would not accompany any dancing. The waltz also arose later in the classical era. Both remained part of the romantic music period, which also saw the rise of various other nationalistic dance forms like the barcarolle, mazurka, ecossaise, ballade and polonaise.  - Grant Robert Gee (born 24 October 1964) is a British film maker, photographer and cinematographer.

He is best known as the bassist and co-founder of English rock bands Joy Division and New Order.  - Bernard Edward Sumner (born 4 January 1956), also briefly known as Bernard Albrecht, is an English singer, songwriter, musician and record producer. He is a founding member of both Joy Division and New Order, and is widely credited with the latter band's move towards electronica and synthpop.  - Post-punk (originally "new musick") is a broad type of rock music that emerged from the punk movement of the 1970s, in which artists departed from punk rock's raw, accessible style to pursue a variety of avant-garde sensibilities. Attempting to break from rock tradition, post-punk artists experimented with sources such as electronic music, black dance music and the avant-garde, as well as novel recording technology and production techniques. The movement also saw the frequent intersection of music with art and politics, as artists incorporated ideas from sources such as modernist literature, critical theory, cinema, and performance art. Accompanying these musical developments were communities that produced independent record labels, visual art, multimedia performances and fanzines in conjunction with the music.  - Joy Division is a 2007 British documentary film on the British post-punk band Joy Division , directed by Grant Gee .

Film critic Philip French : `` Someone says in the film that the revolutionary step they made was to progress from the usual punk group 's angry statement : ' Fuck you . ' Joy Division were the first to say : ' We 're fucked . ' There is a particularly impressive sequence in which dark , despairing tracks of urban alienation and angst from the 1979 album Unknown Pleasures are accompanied by a speeded - up nocturnal journey around Manchester . It has the hallucinatory sci - fi feeling of Jean - Luc Godard 's Alphaville . '' The person being quoted was Tony Wilson .  - Joy Division were an English rock band formed in 1976 in Salford, Greater Manchester.
