Heavy metal (or simply metal) is a genre of rock music that developed in the late 1960s and early 1970s, largely in the United Kingdom and the United States. With roots in blues rock and psychedelic/acid rock, the bands that created heavy metal developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Heavy metal lyrics and performance styles are sometimes associated with aggression and machismo.
The first heavy metal bands such as Led Zeppelin, Black Sabbath and Deep Purple attracted large audiences, though they were often derided by critics. During the mid-1970s, Judas Priest helped spur the genre's evolution by discarding much of its blues influence; Motörhead introduced a punk rock sensibility and an increasing emphasis on speed. Beginning in the late 1970s, bands in the new wave of British heavy metal such as Iron Maiden and Saxon followed in a similar vein. Before the end of the decade, heavy metal fans became known as "metalheads" or "headbangers".
During the 1980s, glam metal became popular with groups such as Mötley Crüe and Poison. Underground scenes produced an array of more aggressive styles: thrash metal broke into the mainstream with bands such as Metallica, Megadeth, Slayer, and Anthrax, while other extreme subgenres of metal such as death metal and black metal remain subcultural phenomena. Since the mid-1990s popular styles have further expanded the definition of the genre. These include groove metal (with bands such as Pantera, Sepultura, and Lamb of God) and nu metal (with bands such as Korn, Slipknot, and Linkin Park), the latter of which often incorporates elements of grunge and hip hop.
Disturbed is an American heavy metal band from Chicago, Illinois, formed in 1994. The band includes vocalist David Draiman, bassist John Moyer, guitarist Dan Donegan, and drummer Mike Wengren. Former band members are vocalist Erich Awalt and bassist Steve Kmak.
The band has released six studio albums, five of which have consecutively debuted at number one on the Billboard 200. Disturbed went into hiatus in October 2011, during which the band's members focused on various side projects, and returned in June 2015, releasing their first album in five years, Immortalized, on August 21, 2015.
Green Day is an American punk rock band formed in 1986 by lead vocalist and guitarist Billie Joe Armstrong and bassist Mike Dirnt. For much of the group's career, the band has been a trio with drummer Tré Cool, who replaced former drummer John Kiffmeyer in 1990 prior to the recording of the band's second studio album, Kerplunk (1991). Guitarist Jason White, who has worked with the band as a touring member since 1999, was an official member from 2012 to 2016.
Green Day was originally part of the punk scene at the DIY 924 Gilman Street club in Berkeley, California. The band's early releases were with the independent record label Lookout! Records. In 1994, its major label debut Dookie (released through Reprise Records) became a breakout success and eventually shipped over 10 million copies in the U.S. Green Day was widely credited, alongside fellow California punk bands Sublime, Bad Religion, The Offspring, Blink-182, and Rancid, with popularizing and reviving mainstream interest in punk rock in the United States.
Green Day's three follow-up albums, Insomniac (1995), Nimrod (1997), and Warning (2000) did not achieve the massive success of Dookie, though they were still successful, with Insomniac and Nimrod reaching double platinum and Warning achieving platinum status. The band's rock opera, American Idiot (2004), reignited the band's popularity with a younger generation, selling six million copies in the U.S. The band's eighth studio album, 21st Century Breakdown, was released in 2009 and achieved the band's best chart performance to date. 21st Century Breakdown was followed up by a trilogy of albums called ¡Uno!, ¡Dos!, and ¡Tré!, which were released in September, November and December 2012 respectively. The band's twelfth studio album, Revolution Radio was released on October 7, 2016 and debuted at number one on the Billboard 200, their third album to do so.
Green Day has sold more than 85 million records worldwide. The group has won five Grammy Awards: Best Alternative Album for Dookie, Best Rock Album for American Idiot, Record of the Year for "Boulevard of Broken Dreams", Best Rock Album for the second time for 21st Century Breakdown and Best Musical Show Album for American Idiot: The Original Broadway Cast Recording. In 2010, a stage adaptation of American Idiot debuted on Broadway. The musical was nominated for three Tony Awards: Best Musical, Best Scenic Design and Best Lighting Design, losing only the first. Also in 2010, Green Day was ranked no. 91 in the VH1 list of the "100 Greatest Artists of All Time". On April 18, 2015, the band was inducted into the Rock and Roll Hall of Fame as a part of the 2015 class in their first year of eligibility.
