Sick of It All is an American hardcore punk band formed in 1986 in Queens, New York City. The band's lineup consists of brothers Lou and Pete Koller on lead vocals and guitars respectively, Armand Majidi on drums, and Craig Setari on bass. Sick of It All is considered a major part of the New York hardcore scene, and by 2020, the band had sold at least half a million records worldwide.

Though their 1989 debut album Blood, Sweat and No Tears was a moderate success, Sick of It All did not achieve commercial success until later albums. After the release of their second album Just Look Around in 1992, East West Records saw the band's potential and signed them in 1993. Sick of It All's third and major label debut album, Scratch the Surface, was released in 1994 to critical acclaim and included the singles "Scratch the Surface" and "Step Down". They released one more album on East West, 1997's Built to Last, before signing with Fat Wreck Chords in 1998, which released the band's next three studio albums. They signed to Abacus Records afterwards, a subsidiary of Century Media. This label released their eighth studio album Death to Tyrants in 2006 to positive reviews (Abacus eventually went out of business, though Sick of It All would remain on Century Media, which released the band's next three albums). Sick of It All's latest album, Wake the Sleeping Dragon!, was released in 2018.

Formed in 1986, the members met while attending Francis Lewis High School in Queens, New York City, the band was formed by Lou Koller on bass and vocals, Pete Koller on guitar and David Lamb on drums. The Koller brothers originally intended for their first band to be named General Chaos, however Lamb proposed calling the band Sick of All, with the intent to abbreviate it to S.O.A. Lou pointed out that another band existed with that name and decided to expand the name to Sick of It All. After recruiting bassist Mark McNeely, the band played their first show on Saturday May 17, 1986, just a month after they formed, at the Right Track Inn in Long Island, supporting Youth of Today, Straight Ahead and Crippled Youth. After this performance, Lamb and McNeely left the band, leading to the brothers hiring Rich Cipriano as bassist and Armand Majidi as a "fill-in" drummer. This lineup also played its first show at the Right Track. The band recorded the Sick of It All demo in 1987 and the band began to play Sunday afternoon matinees at renowned venue CBGB's, and soon after released a self-titled 7" on Revelation Records (which was later re-issued on the tenth anniversary of its release, in 1997).

In 1988, Sick of It All signed to Relativity Records and recorded their first full-length, Blood, Sweat and No Tears, which was released in 1989. The album was met with positive reception and is viewed as a classic in the hardcore genre, Chris Ingham of Metal Hammer called it a "blueprint" for New York hardcore in the 1980s. Whilst Joachim Hiller of Ox-Fanzine said it "heralded a generational shift in NYHC, establishing the tone for the 1990s and the growing popularity of the genre." Sick of it all supported the album with a North American tour alongside Bad Brains, Leeway, D.R.I. and Agnostic Front. In 1991 they released a studio/live EP We Stand Alone. They then took part in the New Titans on the Bloc tour with Sepultura, Sacred Reich and Napalm Death. Their second studio album Just Look Around the following year in 1992. In 1993 they released their first live album titled Live in a World Full of Hate which was recorded during a show in New Jersey.

Sick of It All released their record Scratch the Surface on major label EastWest Records. They also recorded a video for "Step Down" and the title track "Scratch The Surface". The record was the first recorded with long-time friend and former Straight Ahead, Rest in Pieces, Youth of Today and Agnostic Front bass player Craig Setari, who had replaced Rich Cipriano, in early 1993. Scratch the Surface became the band’s first album to chart debuting at number 67 in Germany, and received generally favorable reviews upon its release. In The Trouser Press Guide to '90s Rock (1997), Ira Robbins described the album as "a blast of unreconstructed hardcore in a time and a place where such a thing was once impossible to imagine". Scratch the Surface is retrospectively described as a classic album, and in 2012 it was inducted into the Decibel Hall of Fame. That same year in a interview with Decibel Pete said that he considered Scratch the Surface to be Sick of It All's most important album as it "pushed [the band] up into the higher realm" of songwriting and popularity, whilst Majidi saw it as the band's "quintissential album [...] that we are always forced to try to top." The song “Step Down” also gained a play time on MTV.

The album also helped boost their popularity worldwide and according to Mike Hill of Vice, Scratch the Surface "took NYHC worldwide" and turned Sick of It All into "the closest the hardcore scene has to a household name." With the success of Scratch the Surface it allowed the band to tour worldwide, and In 1995 they made their first appearance on the warped tour.

In 1997, they released their next record on the EastWest sister label Elektra, Built to Last which debuted at number 32 on the US Heatseekers charts. The record featured a number of live staples for the band, including "Us vs. Them", "Busted" and "Good Lookin' Out". Sick of It All toured with Napalm Death and Sepultura during the album cycle, while also making another appearance at that years warped tour. Entertainment Weekly wrote that with the album the band manages "to overcome the genre’s bark-and-lunge cliches simply because they’re so archetypal; these guys can actually make you feel the fury behind a song called 'Us Vs. Them'.” The album also marked the end of Sick of It All's contractual agreement with EastWest. That same year Revelation reissued their debut EP on both vinyl and CD to commemorate its 10th anniversary.

In 1998, Sick of It All signed to independent record label Fat Wreck Chords, owned and run by Fat Mike of NOFX. After releasing the "Potential for a Fall" single – for which another video was filmed, Call To Arms was released in February 1999 and debuted at number 84 on the German charts. This album was also met with positive reception with Kevin Ruggeri of Pitchfork stating “Call to Arms proves once again that Sick of It All are masters of their genre. For over a decade, they have consistently provided the best hardcore their genre has to offer, and with their promise to stick around considered, the future of the scene seems bright indeed.”
