Pop-punk in the context of "Power pop"

Emo (/ˈiːmoʊ/ EE-moh) is a genre of rock music that combines musical characteristics of hardcore punk with emotional, often confessional lyrics. It emerged as a style of hardcore punk and post-hardcore from the mid-1980s Washington, D.C., hardcore scene, where it was known as emotional hardcore or emocore. The bands Rites of Spring and Embrace, among others, pioneered the genre. In the early-to-mid 1990s, emo was adopted and reinvented by alternative rock, indie rock, punk rock, and pop-punk bands, including Sunny Day Real Estate, Jawbreaker, Cap'n Jazz, Mineral, and Jimmy Eat World. By the mid-1990s, Braid, the Promise Ring, American Football, and the Get Up Kids emerged from Midwest emo, and several independent record labels began to specialize in the genre. Meanwhile, screamo, a more aggressive style of emo using screamed vocals, also emerged, pioneered by the San Diego bands Heroin and Antioch Arrow. Screamo achieved mainstream success in the 2000s with bands like Hawthorne Heights, Silverstein, Story of the Year, Thursday, the Used, and Underoath.

The emo subculture signifies a specific relationship between fans and artists and certain aspects of fashion, culture, and behavior. Emo fashion includes skinny jeans, black eyeliner, tight t-shirts with band names, studded belts, and flat, straight, jet-black hair with long bangs. Since the early-to-mid 2000s, fans of emo music who dress like this are referred to as "emo kids" or "emos". The emo subculture was stereotypically associated with social alienation, sensitivity, misanthropy, introversion, and angst. Purported links to depression, self-harm, and suicide, combined with its rise in popularity in the early 2000s, inspired a backlash against emo, with some bands, including My Chemical Romance and Panic! at the Disco, rejecting the emo label because of the social stigma and controversy surrounding it. There has long been controversy over which bands are labeled "emo", especially for bands that started outside traditional emo scenes; a viral website, Is This Band Emo?, was created to address one fan's opinion on this question. Emo and its subgenre emo pop entered mainstream culture in the early 2000s with the success of Jimmy Eat World and Dashboard Confessional, and many artists signed contracts with major record labels. Bands such as My Chemical Romance, AFI, Fall Out Boy, and the Red Jumpsuit Apparatus continued the genre's popularity during the rest of the decade.

My Chemical Romance is an American rock band from New Jersey. The band's current lineup consists of lead vocalist Gerard Way, lead guitarist Ray Toro, rhythm guitarist Frank Iero, and bassist Mikey Way. They are considered one of the most influential rock groups of the 2000s and a major act in the emo and pop-punk genres, despite the band rejecting the former label.

Formed in September 2001 by Gerard, Mikey, Toro, and drummer Matt Pelissier (and later joined by Iero), the band signed with Eyeball Records and released their debut album, I Brought You My Bullets, You Brought Me Your Love, in 2002. They signed with Reprise Records the next year and released their major-label debut, Three Cheers for Sweet Revenge, in 2004. Shortly after the album's release, Pelissier was replaced by Bob Bryar. The album was a commercial success, attaining platinum status over a year later.

Emo pop (alternatively typeset with a hyphen, also known as emo pop-punk and pop-emo) is a fusion genre combining emo with pop-punk, pop music, or both. Emo pop features a musical style with more concise composition and hook-filled choruses. Emo pop has its origins in the 1990s with bands like Jimmy Eat World, the Get Up Kids, Weezer and the Promise Ring. The genre entered the mainstream in the early 2000s with Jimmy Eat World's breakthrough album Bleed American, which included its song "The Middle". Other emo pop bands that achieved mainstream success throughout the decade included Fall Out Boy, the All-American Rejects, My Chemical Romance, Panic! at the Disco and Paramore. The popularity of emo pop declined in the 2010s, with some prominent artists in the genre either disbanding or abandoning the emo pop style.

Fall Out Boy is an American rock band formed in Wilmette, Illinois, a suburb of Chicago, in 2001. The band consists of lead vocalist and rhythm guitarist Patrick Stump, bassist Pete Wentz, lead guitarist Joe Trohman, and drummer Andy Hurley. The band originated from Chicago's hardcore punk scene and was formed by Wentz and Trohman as a pop-punk side project; Stump joined shortly thereafter. The group went through a succession of drummers before Hurley joined. Their debut album, Take This to Your Grave (2003), became an underground success and helped the band gain a dedicated fan base through heavy touring.

With Wentz as the band's lyricist and Stump as the primary composer, Fall Out Boy's 2005 major-label breakthrough, From Under the Cork Tree, produced two hit singles, "Sugar, We're Goin Down" and "Dance, Dance". It went double platinum, transforming the group into superstars and making Wentz a celebrity and tabloid fixture. Fall Out Boy received a Best New Artist nomination at the 2006 Grammy Awards. Infinity on High (2007) debuted at number one on the Billboard 200 with 260,000 first week sales. It produced two worldwide hit singles, "This Ain't a Scene, It's an Arms Race" and "Thnks fr th Mmrs". Their following album, Folie à Deux (2008), was a commercial disappointment and received a mixed response. Following the release of Believers Never Die – Greatest Hits in 2009, the band went on hiatus and the members worked on side projects.
