Rap metal

Rap metal is a subgenre of rap rock and alternative metal music which fuses vocal and instrumental elements of hip hop with heavy metal.

Origins and early development (1980s-early 1990s)
Rap metal originated from rap rock, a genre fusing vocal and instrumental elements of hip hop with rock. The genre's roots are based both in hip hop acts that sampled heavy metal songs, such as Beastie Boys, Cypress Hill, Esham and Run–D.M.C., as well as rock bands who fused heavy metal and hip hop influences, such as 24-7 Spyz and Faith No More. Scott Ian of Anthrax (who helped pioneer the genre) believes Rage Against the Machine invented the genre.

In 1987, New York thrash metal band Anthrax fused hip hop with heavy metal for their extended play I'm the Man, and then were teamed up with Public Enemy for a remake of the latter's "Bring the Noise" that fused hip hop with thrash metal. The next year rapper Sir Mix-a-Lot teamed up with Metal Church for his 1988 single "Iron Man", loosely based upon the Black Sabbath song of the same name. In 1990, rapper Ice-T formed a heavy metal band called Body Count, and while performing at the 1991 Lollapalooza tour performed a set that was half rap songs and half metal songs. Stuck Mojo, a metal band whose vocalist rapped, is considered to be another pioneer of the genre.

Mainstream popularity (1990s-early 2000s)
The 1990s saw the peak of rap metal's mainstream popularity. For instance, the band Faith No More's song Epic was a major success and peaked at number 9 on the Billboard Hot 100. For example, Rage Against the Machine's Evil Empire entered the Billboard 200 at number one in 1996. In 1999, their third studio album, The Battle of Los Angeles, also debuted in top spot in the Billboard 200; it sold 430,000 copies in its first week. Every single on the band's albums became platinum hits.

Biohazard played on the Ozzfest mainstage alongside Ozzy Osbourne, Slayer, Danzig, Fear Factory, and Sepultura. In support of the album, Biohazard embarked on a short co-headlining tour of Europe with Suicidal Tendencies.

On August 18, 1998, Atlantic released rap metal musician Kid Rock's Devil Without a Cause behind the single "Welcome 2 the Party (Ode 2 the Old School)" and Kid Rock went on the Vans Warped Tour to support the album. Sales of "Welcome 2 The Party" and Devil Without a Cause were slow, though the 1998 Warped Tour in Northampton, Massachusetts stimulated regional interest in Massachusetts and New England. This led to substantial airplay of the single "I Am The Bullgod" during the summer and fall of 1998 on Massachusetts rock staples WZLX and WAAF. In early December 1998, while DJing at a club, he met and became friends with MTV host Carson Daly. He talked Daly into getting him a performance on MTV and on December 28, 1998, he performed on MTV Fashionably Loudin Miami, Florida, creating a buzz from his performance, even upstagging Jay-Z. In May, his sales began taking off with the third single "Bawitdaba" and by April 1999, Devil Without a Cause had achieved a gold disc. The following month, Devil, as he predicted, went platinum.

Kid Rock's first major tour was Limptropolis, where he opened for Limp Bizkit with Staind. He solidified his superstardom with a Woodstock 1999 performance and on July 24 of that year, he was double platinum. The following single "Cowboy", a mix of southern rock, country, and rap, was an even bigger hit, making the Top 40. It even became the theme song of WCW's Jeff Jarrett. Rock's next single, the slow back porch blues ballad "Only God Knows Why", was the biggest hit off the album, charting at No. 19 on the Billboard Hot 100. It was one of the first songs to use the autotune effect. By the time the final single, "Wasting Time", was released, the album had sold 7 million copies. Devil Without A Cause was certified 11 times platinum by the RIAA on April 17, 2003. According to soundscan actual sales are 9.3 million as of 2013.

Kid Rock was nominated as Best New Artist at the 2000 Grammy Awards, but lost to Christina Aguilera. He was nominated for "Bawitdaba" for Best Hard Rock Performance, but lost to Metallica's "Whiskey in the Jar".

In 1998, Ice Cube released his long-awaited album War & Peace Vol. 1 (The War Disc) which had some elements of nu metal and rap metal on some tracks. The album debuted at No. 7 on the Billboard 200 chart, selling 180,000 copies in the first week.

A Florida hip hop and rap metal-influenced nu metal band, Limp Bizkit's 1999 album Significant Other climbed to No. 1 on the Billboard 200, selling 643,874 copies in its first week of release. In its second week of release, the album sold an additional 335,000 copies. The band's follow-up album, Chocolate Starfish and the Hot Dog Flavored Water, set a record for highest week-one sales of a rock album with over one million copies sold in the U.S. in its first week of release, with 400,000 of those sales coming on its first day, making it the fastest-selling rock album ever, breaking the record held for 7 years by Pearl Jam's Vs. That same year, Papa Roach's major label debut Infest became a platinum hit.

Cypress Hill incorporated direct heavy metal influences into their 2000 album Skull & Bones, which featured six tracks in which rappers B-Real and Sen Dog were backed by a band including Fear Factory members Christian Olde Wolbers and Dino Cazares and Rage Against the Machine drummer Brad Wilk. B-Real also formed a rap metal group, Kush, with Wolbers, Fear Factory drummer Raymond Herrera and Deftones guitarist Stephen Carpenter. According to B-Real, Kush is more aggressive than other bands in the genre. SX-10, formed in 1996 by Sen Dog, also performs rap rock and rap metal.

In 2000, the rap metal band P.O.D.'s 1999 album The Fundamental Elements of Southtown went platinum and was the 143rd best-selling album of 2000. Late in 2000, Linkin Park released their debut album Hybrid Theory, which remains both the best-selling debut album by any artist in the 21st century, and the best-selling nu metal album of all time. The album was also the best-selling album in all genres in 2001, offsetting sales by prominent pop acts like Backstreet Boys and N'Sync, earning the band a Grammy Award for their second single "Crawling", with the fourth single, "In the End", released late in 2001, becoming one of the most recognized songs in the first decade of the 21st century. The rap rock band Crazy Town also broke into the mainstream success of nu metal with their 1999 album The Gift of Game, especially their number 1 hit single, Butterfly, which peaked at number 1 on many charts including the Billboard Hot 100 during March 2001, remaining on the Hot 100 for 23 weeks. It also peaked at number 1 on the Modern Rock Tracks chart and the Hot Dance Singles chart as well as peaking number 6 on the Rhythmic Top 40, number 2 on the Top 40 Mainstream chart and number 4 on the Top 40 Tracks chart. Their album The Gift of Game peaked at number 9 on the Billboard 200. Worldwide the album sold more than 2.5 million units, with more than 1.5 million in the US alone. Also that year was Saliva's Every Six Seconds which was also a commercial success, debuting at no. 6 on the Billboard 200. In 2001, the band P.O.D.'s Satellite album went triple platinum and peaked at #6 on the Billboard 200 chart.
