Rap rock

Rap rock is a music genre that fuses vocal and instrumental elements of hip hop with various forms of rock. Rap rock's most popular subgenres include rap metal and rapcore, which include heavy metal and hardcore punk-oriented influences, respectively. One of the earliest examples would be "The Magnificent Seven" by The Clash, which fused new wave, hip hop, and funk.

Characteristics
AllMusic describes rap metal as having "big, lurching beats and heavy, heavy riffs" that "occasionally ... [sound] as if the riffs were merely overdubbed over scratching and beat box beats", and described rap rock as having a more organic sound, characterizing many songs in the genre as rock songs in which the vocals were rapped rather than sung. Allmusic also states that the rhythms of rap rock are rooted in that of hip hop, with more funk influences than normal hard rock. Hed PE, which fuses punk rock with hip hop, sometimes incorporates reggae and heavy metal influences. According to Rolling Stone writer Rob Kemp, Incubus' 1997 album S.C.I.E.N.C.E. "links funk metal to the rap metal". Kottonmouth Kings perform a style which they refer to as "psychedelic hip-hop punk rock". Kid Rock incorporates country and Southern rock influences, and is backed by a 10 piece band, while Everlast fuses blues and rock with hip hop, performing with a live band that includes a DJ. An example of rap rock is the album Collision Course (album), it's a collaboration between the rapper Jay Z and the band Linkin Park.

The lyrical themes of rap rock vary. According to Allmusic, "most rap-metal bands during the mid- to late '90s blended an ultra-aggressive, testosterone-heavy theatricality with either juvenile humor or an introspective angst learned through alternative metal". However, as the genre began to become more established, several bands branched out into political or social commentary in their lyrics, most notably Rage Against the Machine and Senser which distinguished them from less politically concerned bands such as Linkin Park and Limp Bizkit.

Although many nu metal bands incorporate hip hop beats, rap rock bands are always fronted by rappers. Rock bands generally not associated with rap rock have experimented with hip hop influences, including rapping. Such bands have included Blondie, Rush, Beck and Cake. Many rappers have been noted for a prominent use of samples derived from rock songs, including Eminem, Ice-T, The Fat Boys, LL Cool J, Public Enemy, Whodini, Vanilla Ice, and Esham.

Early development (1980s)
One of the earliest examples of rapping in rock music is "Year of the Guru" by Eric Burdon and the Animals, a psychedelic rock song in which Eric Burdon, according to AllMusic, "[took] the role of a modern rapper". In 1983, KISS released the song "All Hell's Breakin' Loose" on the album Lick It Up with singer Paul Stanley rapping the verses. In 1986, Run–D.M.C. collaborated with Aerosmith on a remake of the latter's earlier song, "Walk This Way", first released in 1975. The success of the "Walk This Way" remake helped bring hip hop into popularity with a mainstream white audience, following an earlier experimental track by rap artist LL Cool J, "Rock the Bells", where he had fused conventional rap lyrics over a hard rock arrangement. Red Hot Chili Peppers vocalist Anthony Kiedis employed rapping on the band's 1984 self-titled debut album as well as subsequent releases. In a 2002 interview with Penthouse, Kiedis stated "We were early in creating the combination of hardcore funk with hip-hop-style vocals. We became, maybe, an inspiration to Limp Bizkit, Kid Rock, Linkin Park – all these other bands that are doing that now." Beastie Boys, formerly a hardcore punk group, began working in the hip hop genre; their 1986 debut album, Licensed to Ill, largely featured a rock-based sound. The three aforementioned artists all collaborated with producer Rick Rubin, who is credited with creating the rap rock genre. In 1989, Tone-Lōc's "Wild Thing" off of his debut album, Lōc-ed After Dark that reached No. 1 on the Billboard 200 was critically acclaimed and reached No. 2 on the U.S. Billboard Hot 100. In 1991, thrash metal band Anthrax collaborated with political hip hop outfit Public Enemy on a version of the latter's "Bring the Noise", which saw rapped vocals shared between the Anthrax's Scott Ian and Public Enemy's Chuck D over a heavy electric guitar and electric bass riff. Public Enemy's track, "She Watch Channel Zero?!" features Chuck D rapping over a riff from the Slayer song "Angel of Death".

Rap rock began to enter the mainstream arena in the 1990s. American rock bands such as 311, 24-7 Spyz, Faith No More and Rage Against the Machine fused rock and hip hop influences. Simultaneously, British bands like Pop Will Eat Itself and Senser were similarly shaping the genre across Europe. The soundtrack for the 1993 film Judgment Night featured 11 collaborations between hip hop and rock musicians. Urban Dance Squad mixed funk, heavy metal, hip hop and punk. Biohazard, who collaborated with hardcore hip hop group Onyx on the track "Judgement Night" from the soundtrack of the same name, is also considered to be a pioneering act in the genre. Cypress Hill's Black Sunday featured a rock-based sound and artwork which, according to Allmusic reviewer Steve Huey, resembled that of heavy metal bands. Swedish Band Clawfinger were one of the early bands to pioneer Rap Rock and Rapcore sounds outside the US gaining popularity with their debut Deaf Dumb Blind, which sold over 700,000 copies as stated on their Facebook.

Rapcore
Rapcore, punk rap or hip punk is a fusion genre of hip hop and punk rock or hardcore punk. Beastie Boys, formerly a hardcore punk group, began working in the hip hop genre. Their debut album, Licensed to Ill, largely featured a rock-based sound. Biohazard is considered to be a strong influence on the genre's development. Huntington Beach-based punk band Hed PE performs a fusion of styles ranging from hip hop and reggae to punk rock, hardcore punk and heavy metal. Although they are considered to be performers in the rapcore genre, they refer to their musical style as "G-punk". Kottonmouth Kings perform a style which they refer to as "psychedelic hip-hop punk rock". Three of the earliest formative rapcore bands were 311, Rage Against the Machine, and Every Day Life. Professional critic Mark Allan Powell considers the rap rock song "Jesus Freak" by DC Talk, which was marginalized by many critics due to its Christian lyrical content, the turning point of when the popularity of grunge gave way to rapcore.

Among the first wave of bands to gain mainstream success were 311, Bloodhound Gang and Limp Bizkit. Although the popularity of rapcore declined, some believe that rapcore may regain popularity, with younger music fans discovering bands in the genre. Drew Simollardes of the rapcore band Reveille states that "I feel like lately it’s more appropriate. People are sick of a lot of the stuff that’s out there right now."
