Nick Steven Oliveri was born in Los Angeles on October 21, 1971, and was then raised in Palm Springs at the age of 11. His first instrument was a guitar but he later moved to bass. His major influences were Kiss, Black Sabbath, Ramones, Rush and Van Halen. Oliveri was described as having a Spicoli-like lifestyle growing up in his youth.

He began his career in 1987 as a guitarist, when he formed Katzenjammer with bandmates; John Garcia, Josh Homme, Chris Cockrell and Brant Bjork. In early 1989, shortly after Oliveri’s departure, the band changed its name to Sons of Kyuss, and after self-releasing an EP in 1990, the band re-recruited Oliveri on bass to replace Cockrell, and shortened their name to Kyuss.

Nick Oliveri (under the moniker Rex Everything) formed Mondo Generator in 1997 and with friends Josh Homme, Brant Bjork, Rob Oswald, Karl Doyle and others, recorded the debut album, Cocaine Rodeo. The album wouldn’t be released until three years later due to Oliveri and Homme being full-time members of Queens of the Stone Age. The album was released by cult-favorite Southern Lord Records in 2000. There was little support of the album by the way of live shows, and the band gained cult status among the most devoted Queens of the Stone Age fans.

On July 10, 1999, Oliveri and Josh Homme were involved in an altercation with English rock band Terrorvision while Queens of the Stone Age were on tour in London. Oliveri was arrested as a result, but was released several hours later without being charged.

On January 19, 2001, Oliveri was arrested after a performance at Rock in Rio III in Rio de Janeiro, Brazil for performing nude on stage. Oliveri apologised for the incident and stated that he was not aware that it was a crime in Brazil.

In January 2004, following a string of dates touring in Australia, Oliveri was fired from the band, with reasoning at first being aggressive treatment of the band’s fans, later being accusations of possible abuse to his girlfriend. Oliveri has said to have come to the conclusion himself that during a sound check at a show in Spain in 2003 he acted too aggressively to Josh Homme over his relationship with then-girlfriend Brody Dalle after getting too drunk on wine, raising tension between the two.

Since his firing from Queens of the Stone Age, Oliveri has recorded an acoustic LP entitled Demolition Day that was eventually released as a second disk in a limited edition of Mondo Generator’s latest album, Dead Planet: SonicSlowMotionTrails. Although now concentrating on the Mondo Generator project, in September 2006 Oliveri stated “I feel that Queens is something I can contribute to and Josh Homme needs me to do it.”

As of April 2007, Mondo Generator was scheduled to appear on the 12th annual Ozzfest tour (otherwise known as the “FreeFest” tour), but officially dropped off the tour on July 26, 2007 after appearing at four Ozzfest dates. Oliveri stated, “We can’t keep on touring for free! My band’s not free, it’s costing me.”

In early 2008, Nick joined a West Coast offshoot of Moistboyz dubbed Dickie Moist OTC, on bass. In June 2008, Nick joined Los Angeles-based rock band, The Knives, on bass.

On August 7, 2008, Nick Oliveri appeared on stage with Turbonegro to sing “Back to Dungaree High” and “Nervous Breakdown,” the first of which a song that Queens of the Stone Age covered on the Alpha Motherfuckers Turbonegro tribute album, and the latter being a Black Flag cover. The band’s performance at the Øyafestivalen was a 10th Anniversary celebration of their critically hailed album, Apocalypse Dudes.

In June 2010, former Kyuss members Oliveri and Bjork joined Garcia onstage to perform “Green Machine” and “Gardenia” during a headlining appearance by “Garcia Plays Kyuss” at Hellfest in Clisson, France and they also appeared onstage with Garcia in other concerts on the tour.

In November 2010, Oliveri joined Kyuss Lives! with fellow ex band members Garcia and Bjork. The band initially toured Europe, Australian and New Zealand markets in early 2011, and later toured North America. A new studio album was also being planned following the tour. Due to Oliveri’s ongoing legal problems resulting from a July 2011 incident, he was unable to leave the US and Scott Reeder filled in for him on several international dates. After touring domestically in the US with Kyuss Lives! during 2011, Oliveri decided to leave the band in favor of returning to working on Mondo Generator.

In 2010, Oliveri announced that he is now in a new as yet unnamed band with Euroboy and Happy-Tom of Turbonegro, as well as Tommy Akerholdt from Serena-Maneesh.

There was speculation that he would return in Queens of the Stone Age during their summer tour due to Josh Homme’s dedication of “New Fang” to Nick for “new beginnings”. However, this proved to be false. In March 2011, Oliveri stated: “The last time I saw them play was a benefit for Brian O’Connor in L.A., from the Eagles of Death Metal. I was down there and I mentioned to them, “Why don’t I come up and do “Millionaire” or something, and sing it and not play bass?” [Josh] was like, “Nah, I don’t think that’s a good idea yet.” It’s kind of in his court for stuff like that. I don’t think he wants to give anybody the wrong idea. I don’t necessarily know if that would happen. And he’s got a good band—he’s taking the band in the direction he wants it to go.”

On July 12, 2011, Oliveri was arrested for suspicion of felony domestic violence after a standoff with police SWAT team. He allowed his girlfriend to exit the house two hours into the standoff and two hours before the SWAT team made entry into the home and arrested Oliveri. Drugs and a loaded rifle were found in the home. In August 2012, Oliveri’s lawyer reached a plea agreement with prosecutors in his case. Oliveri’s lawyer, Freddy Sayegh, told TMZ, “Mr. Oliveri agreed to plead to one count of possession of cocaine and a dismissal of the remaining six felony counts.” Oliveri’s record in the case will be expunged as long as he completes a court ordered community service, anger management, and remains out of trouble for 6 years.

However, in March 2012, it was revealed that Josh Homme, after persuading bassist Scott Reeder to support him, had filed a federal lawsuit against John Garcia and Brant Bjork alleging “trademark infringement and consumer fraud” over the use of the Kyuss name despite the fact Brant Bjork had originally created the name. Nick Oliveri left Kyuss later that month after it was revealed that Garcia and Bjork had tried to take control of the Kyuss trademark.

In December 2012, he announced his return to Kyuss Lives!, however all touring and promotions since have not featured Oliveri. In August 2013, singer John Garcia said that the band “is a three-piece band with [himself], Brant [Bjork, drummer] and Bruno [Fevery, guitarist]. It always will be.” and described Oliveri as “an honorary band member”.

In July 2013 while on tour in Alaska, Oliveri met members of Men With Guns, Lowell George Granath and Cody Kniceley. They formed a band called The Situationalists and recorded two demo tracks days later. An LP was planned, but as of Fall 2015 has not materialized.

In April 2014, Moistboyz opened for Queens of the Stone Age at a concert at the Keller Auditorium in Portland, Oregon. Oliveri then joined Queens of the Stone Age on stage for the first time in over a decade to sing “You Think I Ain’t Worth a Dollar, But I Feel Like a Millionaire.”

In late 2015 Oliveri joined Russian punk rock band Svetlanas as recording and touring bassist. Their new record was recorded at Josh Homme’s Pink Duck studios in California.

In November 2016, Oliveri announced the release of a series of compilations titled N.O. Hits At All, to be issued on Heavy Psych Sounds Records. Oliveri commented “…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. So get your head right, put this record on and play it loud!” N.O. Hits At All Vol.1 was issued on January 27, 2017. N.O. Hits At All Vol.2 was issued on July 7, 2017. N.O. Hits At All Vol.3 was released on October 20, 2017, a day before Oliveri’s birthday. N.O. Hits At All Vol.4 was released on February 23, 2018. N.O. Hits At All Vol.5 was released on October 12, 2018.
