Short answers, pulled from the story.
Korn is from Bakersfield, California, and was originally formed in 1993. Three of the founding members, James Shaffer, Reginald Arvizu, and David Silveria, had previously played together in the band L.A.P.D. before recruiting Jonathan Davis and Brian Welch.
The backwards R in KoЯn was inspired by the logo of the toy retailer Toys R Us, where several band members had previously worked. James Shaffer came up with the idea of spelling the name with a K and a reversed R to make it visually distinctive.
As of 2021, Korn had sold more than 40 million records worldwide. Fourteen of their official releases peaked in the top ten of the Billboard 200, with eight reaching the top five, tying them with Van Halen for the most top-ten records among rock and metal artists.
Brian Welch left Korn in early 2005 after becoming a Christian and crediting the church with helping him overcome a methamphetamine addiction he said no other treatment had addressed. He made the announcement in front of a crowd of 10,000 across three services at Valley Bible Fellowship in Bakersfield, California. Welch rejoined the band permanently in 2013.
Korn drew heavily from Faith No More, particularly the 1989 album The Real Thing, which Jonathan Davis credited with showing that heavy music did not have to be traditional metal. The band also cited Cypress Hill, Red Hot Chili Peppers, Mr. Bungle, Rage Against the Machine, Nine Inch Nails, and hip hop artists as key influences. Davis said directly: if there is no Cypress Hill, there would be no Korn.
Korn has won two Grammy Awards from eight nominations. "Here to Stay" won Best Metal Performance, and "Freak on a Leash" won Best Music Video, Short Form. The band also received nominations for Best Metal Performance for "Shoots and Ladders," "No Place to Hide," and "Did My Time," among others.
