<P> Emo broke into mainstream culture in the early 2000s with the platinum - selling success of Jimmy Eat World's Bleed American (2001) and Dashboard Confessional's The Places You Have Come to Fear the Most (2003). The new emo had a far greater appeal amongst adolescents than its earlier incarnations . At the same time, use of the term emo expanded beyond the musical genre, becoming associated with fashion, a hairstyle and any music that expressed emotion . The term emo has been applied by critics and journalists to a variety of artists, including multi-platinum acts such as Fall Out Boy and My Chemical Romance and disparate groups such as Paramore and Panic! at the Disco, even when they protest the label . </P> <P> In the early 2000s, a new group of bands that played a stripped down and back - to - basics version of guitar rock, emerged into the mainstream . They were variously characterised as part of a garage rock, post-punk or new wave revival . There had been attempts to revive garage rock and elements of punk in the 1980s and 1990s and by 2000 several local scenes had grown up in the US . The Detroit rock scene included: The Von Bondies, Electric Six, The Dirtbombs and The Detroit Cobras and that of New York: Radio 4, Yeah Yeah Yeahs and The Rapture . </P> <P> The commercial breakthrough from these scenes was led by bands including The Strokes, who emerged from the New York club scene with their début album Is This It (2001) and The White Stripes, from Detroit, with their third album White Blood Cells (2001). They were christened by the media as the "The" bands, and dubbed "The saviours of rock' n' roll", leading to accusations of hype . A second wave of bands that managed to gain international recognition as a result of the movement included Black Rebel Motorcycle Club, The Killers, Interpol and Kings of Leon from the US . </P> <P> Metalcore, originally an American hybrid of thrash metal and hardcore punk, emerged as a commercial force in the mid-2000s . It was rooted in the crossover thrash style developed two decades earlier by bands such as Suicidal Tendencies, Dirty Rotten Imbeciles, and Stormtroopers of Death and remained an underground phenomenon through the 1990s . By 2004, melodic metalcore, influenced by melodic death metal, was sufficiently popular for Killswitch Engage's The End of Heartache and Shadows Fall's The War Within to debut at number 21 and number 20, respectively, on the Billboard album chart . Lamb of God, with a related blend of metal styles, hit the number 2 spot on the Billboard charts in 2009 with Wrath . The success of these bands and others such as Trivium, who have released both metalcore and straight - ahead thrash albums, and Mastodon, who played in a progressive / sludge style, inspired claims of a metal revival in the United States, dubbed by some critics the "New Wave of American Heavy Metal". </P>
