Nick Steven Oliveri (born October 21, 1971) is an American musician from Palm Desert, California. He plays bass guitar, acoustic guitar, electric guitar, and is a vocalist. He is most widely known as a bassist with Kyuss, Queens of the Stone Age, and The Dwarves, and has also performed with the reunited Kyuss under the names Kyuss Lives! and Vista Chino. As a bandleader, his main project is Mondo Generator, a punk/metal hybrid that he formed in 1997. Born in Los Angeles, Oliveri began his career in 1987 with John Garcia, Brant Bjork, Josh Homme, and Chris Cockrell under the name Katzenjammer. In early 1989, after Oliveri's departure to play in other bands, the band would change its name to Sons of Kyuss, later shortening the name to Kyuss. He later rejoined the band, playing on the albums Wretch (1991) and Blues for the Red Sun (1992). Oliveri would leave Kyuss again in early 1992, shortly after his father died in a car accident. Following his departure from Kyuss he joined The Dwarves as an on-again, off-again bassist under the moniker Rex Everything. However he is perhaps best known as a member of Queens of the Stone Age from 1998 to 2004. Oliveri is also a solo artist and frequent contributor to his friends' albums and tours, including Winnebago Deal, Mark Lanegan Band, Masters of Reality, Turbonegro, Moistboyz aka Dickie Moist and the O.T.C., and The Knives. In the past he has been involved with The Desert Sessions Vol. 4 (1998) and Vol. 6 (1999). Oliveri is known for playing bare chested and sometimes naked at gigs. He was arrested in Brazil, after performing nude on stage at the Rock in Rio festival in Rio de Janeiro. He is one half of the acoustic duo The Uncontrollable, with The Dwarves frontman Blag Dahlia. Oliveri on the record: "Now for the first time, all these songs and bands I've recorded with over the past 25 years are together and available to you to trip out on." Vol. 4 features The Uncontrollable, Biblical Proof Of UFOs, Death Acoustic, Loading Data, The Dwarves, He Who Can Not Be Named, Rattlin' Bones, and Jennifer Finch's Brats On The Beat featuring the Gabba Gabba Heys.
