Which band would be classified as Christian nu metal, P.O.D. or Swervedriver?
P.O.D.
Swervedriver
Swervedriver are an English alternative rock band formed in Oxford in 1989 around core members Adam Franklin and Jimmy Hartridge.
 Between 1989 and 1998, the band released four studio albums and numerous EPs and singles despite a considerable flux of members, managers, and record labels.
 By 1993 the band’s lineup had settled with Franklin on vocals/guitar, Hartridge on guitar, Jez Hindmarsh on drums, and Steve George on bass.
 They had emerged with a heavier rock sound than their shoegaze contemporaries, and over the next five years it evolved to include elements of psychedelia, classic pop, and indie rock.
 In 2008, the band reunited for touring purposes.
 They released their first new single in fifteen years in September 2013, and their first full-length album in seventeen years in March 2015.
P.O.D.
Payable on Death (abbreviated P.O.D.) is a Christian nu metal band formed in 1992 and based in San Diego, California.
 The band's line-up consists of vocalist Sonny Sandoval, drummer Wuv Bernardo, guitarist Marcos Curiel, and bassist Traa Daniels.
 They have sold over 12 million records worldwide.
 Over the course of their career, the band has received three Grammy Award nominations, contributed to numerous motion picture soundtracks and toured internationally.
 With their third studio album, "The Fundamental Elements of Southtown", they achieved their initial mainstream success; the album was certified platinum by the RIAA in 2000.
 Their following studio album, "Satellite", continued the band's success with the singles, "Alive" and "Youth of the Nation", pushing it to go triple platinum.
Nu metal
Nu metal (also known as nü-metal and aggro-metal ) is a form of alternative metal that combines elements of heavy metal music with elements of other music genres such as hip hop, alternative rock, funk and grunge.
 Nu metal bands have drawn elements and influences from a variety of musical styles, including multiple genres of heavy metal.
 Nu metal rarely features guitar solos; the genre is heavily syncopated and based on guitar riffs.
 Many nu metal guitarists use seven-string guitars that are down-tuned to play a heavier sound.
 DJs are occasionally featured in nu metal to provide instrumentation such as sampling, turntable scratching and electronic backgrounds.
 Vocal styles in nu metal include singing, rapping, screaming and growling.
 Nu metal is one of the key genres of the new wave of American heavy metal. Strangers Only
Strangers Only is the second studio album by American nu metal band My Ticket Home.
 It was released on September 3, 2013 through Rise Records.
 The album's musical style is a drastic departure from the metalcore and post-hardcore sound of the band's previous releases, instead showcasing a nu metal sound with metalcore elements.
 It was the band's final album with Rise Records, after the band left the label and would later sign with Spinefarm Records. List of nu metal bands
The following is a list of bands that have played nu metal.
 Nu metal (also known as nü-metal and aggro-metal), is a form of alternative metal music that merges elements of heavy metal with elements of other music genres like hip hop, grunge, alternative rock and funk.
 Korn, a band formed in 1993, is generally considered the first nu metal group. Roots (Sepultura album)
Roots is the sixth studio album by Brazilian heavy metal band Sepultura.
 It was released in Europe on  20, 1996 (1996--) and in the U.S. three weeks later on March 12 by Roadrunner Records.
 It is the band's last studio album to feature founding member and vocalist/rhythm guitarist Max Cavalera.
 Following the shift to slower tempos and Latin-tinged rhythms on the album "Chaos A.D.", "Roots" delves even further into Brazilian musical textures and features significant contributions from Brazilian musician Carlinhos Brown, who guided and arranged the sections throughout the album that feature ensemble percussion playing.
 The song "Lookaway" also features guest appearances by Korn vocalist Jonathan Davis, former Korn drummer David Silveria, former Limp Bizkit turntablist DJ Lethal, and Faith No More/Mr. Bungle/Tomahawk/Fantômas vocalist Mike Patton.
 The album draws influence from the then-surging nu metal movement, specifically Korn (whose first two albums were also produced by Ross Robinson) and Deftones.
 (After leaving the band, Max Cavalera would continue to pursue the nu metal and "world" stylings of "Roots" with his solo project Soulfly.)
 Since its release, "Roots" has sold over 2 million copies worldwide. Nu metalcore
Nu metalcore (sometimes referred to as nu metal revival or new nu metal) is the fusion of nu metal and metalcore popularized in the 2010s, with sometimes thrash metal, death metal and groove metal.
 Some of the notable groups have also taken influence from R&B, pop, post-hardcore, and deathcore.
 The fusion is characterized by typical metalcore vocals and instrumentation often accompanied by down-tuned guitars, heavy bass, rapping, spoken word, soulful singing, funk samples, or turntablism. 6Gig
6Gig is a band from the Portland, Maine area.
 It is classified by reviewers as an aggro or nu metal band, although the band is quite hard to classify because the only trait that the band shared with other nu metal bands is downtuned guitars.
 They actively played at clubs and different locations throughout New England.
 They released two CDs and several singles, as well as a video for the song "Hit the Ground" that received airplay on MTV2.
 Before the release of "Mind Over Mind", the band parted ways with drummer Dave Rankin and replaced him with Jason Stewart.
 Shortly after this, Rankin was found dead from a mixture of prescription drugs and alcohol. Korn (album)
Korn (printed and stylized as KoЯn) is the debut studio album by American nu metal band Korn.
 It was released on October 11, 1994, through Immortal/Epic Records.
 Before recording the album, the band was approached by Immortal/Epic Records after a performance at Huntington Beach, California.
 The band signed to their label because they didn't want to "sign away all of their creative freedom."
 The band would record at Indigo Ranch Studios in Malibu, California with producer Ross Robinson, who also produced their 1993 demo "Neidermayer's Mind".
 The recording took place from May to June 1994.
 After the recordings, Korn toured with Biohazard and House of Pain. Travail (band)
Travail was a Christian nu metal / rapcore band based in the Dallas/Fort Worth area in Texas.
 Fronted by Matt Leslie, it had an intense following at Club 412, a local church-sponsored lounge and music venue located in southwest Fort Worth.
 Stylistic comparisons were often drawn between their sound and that of secular rock acts popular at the time such as Korn and Limp Bizkit.
 The band was signed on Pluto Records and then were picked up by national label Metro One.
 After releasing their second album, Beautiful Loneliness, on the Metro One label, Travail received a nomination for the 2001 Dove Awards in the Hard Music Recorded Song category.
 Before touring much under the new label, however, Travail broke up.
 Their most requested song, "Judge Me" is still a very popular song and the video for "Return" is still a popular video among those who enjoy the rapcore/nu metal genre.
