After signing to Epic's Immortal imprint, they issued their debut album in late 1994; thanks to a relentless tour schedule that included stints opening for Ozzy Osbourne, Megadeth, Marilyn Manson, and 311, the record slowly but steadily rose in the charts, eventually going gold. Its 1996 follow-up, Life Is Peachy, was a more immediate smash, reaching the number three spot on the pop album charts. The following summer, they headlined Lollapalooza, but were forced to drop off the tour when Shaffer was diagnosed with viral meningitis. While recording their best-selling 1998 LP Follow the Leader, Korn made national headlines when a student in Zeeland, Michigan, was suspended for wearing a T-shirt emblazoned with the group's logo (the school's principal later declared their music "indecent, vulgar, and obscene," prompting the band to issue a cease-and-desist order). Their annual Family Values tour also started in 1998, featuring a lineup that consisted of Korn collaborators such as Limp Bizkit and Ice Cube and like-minded artists such as Rammstein. The tour was an enormous success, so much so that it continued on with Korn overseeing the lineup for years after.

Issues followed in 1999, and in typical Korn fashion they debuted their new single in an episode of South Park. The band toured behind the album into the next year, but their efforts were cut short by an injury that took out drummer David Silveria. They hired former Faith No More drummer Mike Bordin to help them finish the remaining shows, and took a short rest before joining a summer tour with Metallica, Kid Rock, Powerman 5000, and System of a Down. (Silveria later returned amid rumors of leaving the band for a fashion career, but these stemmed from some modeling work he had done before his injury.) In the meantime, Fieldy released a gangsta rap album and Davis scored the film Queen of the Damned, but at the end of 2001 the band reunited as a unit and entered the studio. A few shows with Static-X helped iron the wrinkles out of the new material, and by the next summer they had Untouchables ready for release. Korn did a run of Ozzfest dates in support, and the album was another smash hit. The self-produced Take a Look in the Mirror arrived in 2003. Billed by Korn as a reconsideration of their sound, the album was accompanied by the Back to Basics tour of smaller venues.

In 2005, Welch left the band, evidently due to his newfound Christian faith. But Korn continued on, playing shows that summer as a quartet and signing an expansive recording and development deal with Virgin. The following December they released See You on the Other Side, a number three hit that featured a batch of songs co-written with hitmaking production team the Matrix. Live & Rare, an aptly titled disc of live recordings and rarities, was released in May 2006, with the live acoustic recording MTV Unplugged following in March 2007. Later that year, after returning to the studio, this time without drummer David Silveria, the band resurfaced with an underwhelming album appropriately named Untitled. The band found a permanent drummer by way of Army of Anyone's Ray Luzier. In 2010, it was announced that Korn had signed with Roadrunner Records, and later that year they released their ninth studio album, Korn III: Remember Who You Are. Looking to expand in new directions, Korn sought out electronic producers like Skrillex and Noisia, who helped them infuse their already heavy sound with pounding dubstep on their electronic-tinged tenth album, 2011's The Path of Totality. Their new sound was chronicled live the following year on Live at the Hollywood Palladium.
