Joy Division were an English post-punk band formed in 1976 in Salford, Greater Manchester. Originally named Warsaw, the band consisted of singer-songwriter Ian Curtis, guitarist and keyboardist Bernard Sumner, bass player Peter Hook and drummer Stephen Morris. The band was formed by Sumner and Hook after attending a 4 June 1976 Sex Pistols concert at the Lesser Free Trade Hall in Manchester. While Joy Division's early recordings were heavily influenced by early punk, they evolved a unique sound, aided by producer Martin Hannett, which earned their reputation as pioneers of the post-punk movement.
On 20 July 1976, childhood friends Sumner and Hook separately attended a Sex Pistols show at the Manchester Lesser Free Trade Hall. Both were was inspired by the Pistol's performance. The following day Hook borrowed PS35 from his mother to buy a bass guitar. Sumner said that he felt that they "destroyed the myth of being a pop star, of a musician being some kind of god that you had to worship". They formed a band with Terry Mason, who had also attended the gig. Sumner bought a guitar, and Mason a drum kit. They invited schoolfriend Martin Gresty to join as vocalist, but he turned them down after getting a job at a local factory. An advertisement was placed in the Virgin Records shop in Manchester for a vocalist. Ian Curtis, who knew them from earlier gigs, responded and was hired without audition. Sumner said that he "knew he was all right to get on with and that's what we based the whole group on. If we liked someone, they were in". Buzzcocks manager Richard Boon and frontman Pete Shelley have both been credited with suggesting the band name "Stiff Kittens", but settled on "Warsaw" shortly before their first gig, referencing David Bowie's song "Warszawa". Warsaw debuted on 29 May 1977 at the Electric Circus, supporting the Buzzcocks, Penetration and John Cooper Clarke. They received immediate national exposure due to reviews of the gig in the NME by Paul Morley and in Sounds by Ian Wood. Tony Tabac played drums that night after joining the band two days earlier. Mason was soon made the band's manager and Tabac was replaced on drums in June 1977 by Steve Brotherdale, who also played in the punk band Panik. During his tenure with Warsaw, Brotherdale tried to get Curtis to leave the band and join Panik and even got Curtis to audition for the band. In July 1977, Warsaw recorded a set of five demo tracks at Pennine Sound Studios, Oldham. Uneasy with Brotherdale's aggressive personality, the band fired him soon after the demo sessions. Driving home from the studio, they pulled over and asked Brotherdale to check on a flat tyre; when he got out of the car, they sped off. In August 1977, the band placed an advertisement in a music shop window seeking a replacement drummer. Stephen Morris, who had attended the same school as Curtis, was the sole respondent. Deborah Curtis, Ian's wife, stated that Morris "fitted perfectly" with the other men, and that with his addition Warsaw became a "complete 'family'". To avoid confusion with the London punk band Warsaw Pakt, the band renamed themselves Joy Division in early 1978, borrowing their new name from the sexual slavery wing of a Nazi concentration camp mentioned in the 1955 novel House of Dolls. In December, the group recorded what became their debut EP, An Ideal for Living, at Pennine Sound Studio and played their final gig as Warsaw on New Year's Eve at The Swinging Apple in Liverpool. Billed as Warsaw to ensure an audience, the band played their first gig as Joy Division on 25 January 1978 at Pip's Disco in Manchester.

Did Stephen Morris fit in pretty well?

Avenged Sevenfold (sometimes abbreviated as A7X) is an American heavy metal band from Huntington Beach, California, formed in 1999. The band's current lineup consists of lead vocalist M. Shadows, rhythm guitarist and backing vocalist Zacky Vengeance, lead guitarist and backing vocalist Synyster Gates, bassist and backing vocalist Johnny Christ, and drummer Brooks Wackerman. Avenged Sevenfold is known for its diverse rock sound and dramatic imagery in album covers and merchandise. Avenged Sevenfold emerged with a metalcore sound on the band's debut Sounding the Seventh Trumpet and continued this sound through their second album Waking the Fallen.
The band's influences include Guns N' Roses, Iron Maiden, Megadeth, Pantera, Bad Religion, Dream Theater, Motorhead, Metallica, Black Sabbath, Led Zeppelin, The Rolling Stones, In Flames, At the Gates, Helloween, Queensryche, System of a Down, AC/DC, NOFX, Alice in Chains, Black Flag, Corrosion of Conformity, Suicidal Tendencies, Misfits, Slayer, The Vandals, Soundgarden, Rage Against the Machine, Korn, Slipknot, Deftones, Beastie Boys, Biohazard, Type O Negative, Anthrax and AFI. The band has been categorized under many genres of heavy music. Mainly categorized as heavy metal, hard rock, progressive metal and metalcore, Avenged Sevenfold's music has evolved over most of the band's career. At first, the band's debut album Sounding the Seventh Trumpet consisted almost entirely of a metalcore sound; however, there were several deviations from this genre, most notably in "Streets", which shows a punk rock style, and "Warmness on the Soul", which is a piano ballad. On Waking the Fallen, the band displayed a metalcore style once more, but added more clean singing and leaned a bit more towards metal and bit less close to hardcore. In the band's DVD All Excess, producer Andrew Murdock explained this transition: "When I met the band after Sounding the Seventh Trumpet had come out before they had recorded Waking the Fallen, M. Shadows said to me 'This record is screaming. The record we want to make is going to be half-screaming half-singing. I don't want to scream anymore. And the record after that is going to be all singing'." On City of Evil, Avenged Sevenfold's third album, the band chose to abandon the metalcore genre, using a more hard rock and heavy metal style. Avenged Sevenfold's self-titled album, however, has some experiments with other music genres than that from City of Evil, most notably in "Dear God", which shows a country style and "A Little Piece of Heaven", which is circled within the influence of Broadway show tunes, using primarily brass instruments and stringed orchestra to take over most of the role of the lead and rhythm guitar. Nightmare contains further deviations, including a piano ballad called "Fiction", progressive metal-oriented track "Save Me" and a heavy metal sound with extreme vocals and heavier instrumentation on "God Hates Us". The band's sixth studio album Hail to the King shows more of a classic metal sound and a riff-oriented approach. On their newest album The Stage, the band explores further into progressive metal, blending it with elements of thrash metal. In the past, Avenged Sevenfold has also been described as alternative metal, screamo, and pop punk metal. The band has been criticized for "not being metal enough". Vocalist M. Shadows responded to this with, "we play music for the sake of music, not so that we can be labeled a metal band. That's like telling us we aren't punk enough. Who cares?" Avenged Sevenfold is one of the notable acts of the New Wave of American Heavy Metal.

What are some more important aspects regarding the style and influences?
