# Les Claypool
**Les Claypool** (born 1963, [Richmond, California](https://www.edgepedia.org/richmond-california)) is an American bassist, singer, and songwriter, best known as the founder, bassist, and vocalist of the alternative rock band Primus and as the writer of the [South Park](https://www.edgepedia.org/south-park) theme song. His slap-driven, fretless-heavy playing and nasal, character-based vocals made him one of the most distinctive figures in 1990s rock, and he has sustained a parallel career of side projects including Oysterhead, Colonel Claypool's Fearless Flying Frog Brigade, and the Claypool Lennon Delirium with Sean Ono Lennon.[1](https://www.liverate.com/artists/les-claypool) • [2](https://redlightmanagement.com/artists/les-claypool/)

## Early life and the Metallica audition
Claypool grew up in a family of mechanics in El Sobrante, California, where his high school classmates included future [Metallica](https://www.edgepedia.org/metallica) guitarist [Kirk Hammett](https://www.edgepedia.org/kirk-hammett).[7](https://www.theguardian.com/music/2026/mar/16/we-did-disneyland-on-mind-altering-substances-primus-frontman-les-claypool-on-being-rocks-great-joker-and-why-metallica-rejected-him) He chose the bass over guitar because, in his words, "the guitar sounded kind of wimpy," and he cited Rush's Geddy Lee and funk players such as [Larry Graham](https://www.edgepedia.org/larry-graham) as early influences.[15](https://guitar.com/news/music-news/les-claypool-chose-bass-guitar-sounded-wimpy/) Before Primus, he cut his teeth playing R&B in Hells Angels bars in northern California, and played in the progressive metal band Blind Illusion.[7](https://www.theguardian.com/music/2026/mar/16/we-did-disneyland-on-mind-altering-substances-primus-frontman-les-claypool-on-being-rocks-great-joker-and-why-metallica-rejected-him) • [16](https://www.sfgate.com/music/popquiz/article/pop-quiz-q-a-with-les-claypool-2833119.php)
**The 1986 audition.** After Cliff Burton's death, Metallica auditioned Claypool for the vacant bass slot in late 1986. He later admitted he misread the room: "We played a song or two and I said, 'Hey, you guys want to jam on some Isley Brothers?' Nobody laughed."[6](https://www.guitarworld.com/artists/bassists/les-claypool-looks-back-on-his-disastrous-metallica-audition) In the *Behind the Music* documentary, [James Hetfield](https://www.edgepedia.org/james-hetfield) gave a different reason, saying Claypool "was too good" and should do his own thing; Claypool has scoffed at that explanation, attributing the rejection to a personality and image mismatch, complete with a blonde Mohawk and baggy skater pants.[6](https://www.guitarworld.com/artists/bassists/les-claypool-looks-back-on-his-disastrous-metallica-audition)
## Primus
Claypool founded Primus in 1984, initially under the name Primate, playing over a drum machine with childhood friend Todd Huth on guitar.[4](https://scholar.lib.vt.edu/VA-news/ROA-Times/issues/1993/rt9310/931029/10290077.htm) • [17](https://www.guitarworld.com/artists/guitarists/todd-huth-primus-sausage-fearless-flying-frog-brigade) A cease-and-desist letter over the name Primate led him to the dictionary and the name Primus.[17](https://www.guitarworld.com/artists/guitarists/todd-huth-primus-sausage-fearless-flying-frog-brigade) With $3,000 borrowed from Claypool's mechanic father, the group recorded its first album, *Suck on This*, in 1989.[4](https://scholar.lib.vt.edu/VA-news/ROA-Times/issues/1993/rt9310/931029/10290077.htm) Huth left in 1989 and was replaced by [Larry LaLonde](https://www.edgepedia.org/larry-lalonde); with drummer [Tim Alexander](https://www.edgepedia.org/tim-alexander), the classic lineup recorded *Frizzle Fry* (1990) and signed with the newly founded Interscope in 1991.[17](https://www.guitarworld.com/artists/guitarists/todd-huth-primus-sausage-fearless-flying-frog-brigade) • [6](https://www.guitarworld.com/artists/bassists/les-claypool-looks-back-on-his-disastrous-metallica-audition)
**Mainstream success.** *Sailing the Seas of Cheese* (1991), with singles such as "Jerry Was a Race Car Driver," made Primus one of the most visible bands in American alternative rock, and the album went platinum, as did 1993's *Pork Soda*.[7](https://www.theguardian.com/music/2026/mar/16/we-did-disneyland-on-mind-altering-substances-primus-frontman-les-claypool-on-being-rocks-great-joker-and-why-metallica-rejected-him) "Wynona's Big Brown Beaver" earned a Grammy nomination.[8](https://www.musicradar.com/guitars/bass-guitars/i-said-hey-you-guys-want-to-jam-on-some-isley-brothers-nobody-laughed-les-claypool-remembers-his-audition-for-metallica) In 1996, South Park creators [Trey Parker](https://www.edgepedia.org/trey-parker) and [Matt Stone](https://www.edgepedia.org/matt-stone) invited the band to record the theme song for their new TV show.[18](https://www.loudersound.com/bands-artists/biographies/there-was-a-giant-red-welt-on-my-chest-and-at-my-feet-there-was-a-huge-pigs-foot-with-a-big-toenail-on-it-how-the-worlds-weirdest-band-went-from-cult-outsiders-to-mtv-mainstays)
The band's catalog runs from *Suck on This* (1989) through *Pork Soda* (1993), *Tales from the Punchbowl* (1995), *The Brown Album* (1997), *Antipop* (1999), and, after a hiatus, *Green Naugahyde* (2011), *Primus & the Chocolate Factory* (2014), *The Desaturating Seven* (2017), *Conspiranoid* (2022), and the EP *A Handful of Nuggs* (2026).[19](https://www.lesclaypool.com/) *The Desaturating Seven*, a concept album based on Ul de Rico's 1978 children's book *The Rainbow Goblins*, was recorded with the classic lineup and drew on [King Crimson](https://www.edgepedia.org/king-crimson) and Rush influences.[20](https://www.loudersound.com/features/primus-the-desaturating-seven)
## Playing style and instruments
Claypool's technique combines slap bass, which he prefers to call "thumpin' and pluckin'" after Larry Graham, with tapping, chords, hammer-ons and pull-offs, and fast-moving triplets and quadruplets.[21](https://www.musicradar.com/news/les-claypool-i-always-squirm-when-people-say-slap-bass-its-thumpin-and-pluckin) • [22](https://www.guitarworld.com/features/play-bass-like-les-claypool) He has described his approach as holding down the root of the bass while also playing the rhythm guitar parts, which gives Primus its unusual, bass-forward texture.[7](https://www.theguardian.com/music/2026/mar/16/we-did-disneyland-on-mind-altering-substances-primus-frontman-les-claypool-on-being-rocks-great-joker-and-why-metallica-rejected-him)
**Instruments.** He is long associated with custom basses by Brooklyn luthier Carl Thompson, from 4-string instruments to the 6-string fretless on which he first recorded on *Sailing the Seas of Cheese*; he has said writing on that instrument felt "like wrestling an octopus," and produced the riff to "Jerry Was a Race Car Driver."[22](https://www.guitarworld.com/features/play-bass-like-les-claypool) In recent years he has played his own Pachyderm bass design, which he says achieved the tone he had sought for 30 years, alongside an NS upright bass.[21](https://www.musicradar.com/news/les-claypool-i-always-squirm-when-people-say-slap-bass-its-thumpin-and-pluckin) • [9](https://www.guitarworld.com/features/les-claypool-ill-go-20-years-without-changing-my-gear-and-then-ill-say-this-sucks-ive-got-to-change-everything) He also plays the Whamola, a one-string instrument struck with a stick, featured on the Frog Brigade song "Whamola" and in variations of the South Park and [Robot Chicken](https://www.edgepedia.org/robot-chicken) themes.[10](https://www.guitarworld.com/gear/bass-guitars/bass-gear-round-up-may-2026)
## Side projects
Claypool has run a succession of projects outside Primus, most of them with deliberately outlandish names:[8](https://www.musicradar.com/guitars/bass-guitars/i-said-hey-you-guys-want-to-jam-on-some-isley-brothers-nobody-laughed-les-claypool-remembers-his-audition-for-metallica)
- **Sausage**, the 1994 reunion of Primus's original lineup with Todd Huth and Jay Lane, which recorded *Riddles Are Abound Tonight*.[11](https://www.worldradiohistory.com/Archive-All-Music/CM-Canadian-Musician/90s/Canadian-Musician-1994-08.pdf)
- **Colonel Claypool's Fearless Flying Frog Brigade**, an improvisation-heavy ensemble whose releases include *Purple Onion* (2002) and *The Return of the Live Frogs Vol 1* (2026).[19](https://www.lesclaypool.com/)
- **Oysterhead**, a supergroup with Phish guitarist [Trey Anastasio](https://www.edgepedia.org/trey-anastasio) and former Police drummer [Stewart Copeland](https://www.edgepedia.org/stewart-copeland), which released *The Grand Pecking Order* in 2001.[19](https://www.lesclaypool.com/)
- **Colonel Claypool's Bucket of Bernie Brains**, with guitarist [Buckethead](https://www.edgepedia.org/buckethead) and former Funkadelic keyboardist Bernie Worrell (*The Eyeball in the Sky*, 2004).[19](https://www.lesclaypool.com/)
- **Duo de Twang**, a two-man project with guitarist Bryan Kehoe (*Four Foot Shack*, 2014).[23](https://ufdcimages.uflib.ufl.edu/AA/00/06/92/17/00126/01-09-2014.pdf)
- **The Claypool Lennon Delirium**, formed in 2015 with Sean Ono Lennon after the Ghost of a Saber Tooth Tiger toured with Primus; its albums include *Monolith of Phobos* (2016), *South of Reality* (2019), and the AI-themed concept album *The Great Parrot-Ox and the Golden Egg of Empathy* (2026).[24](https://www.kerrang.com/claypool-lennon-delirium-interview-les-claypool-sean-lennon-primus-beatles-great-parrot-ox-and-the-golden-egg-of-empathy) • [19](https://www.lesclaypool.com/)
He has also collaborated with Tom Waits and Adrian Belew, and in 2021 released the short film *Precious Metals* with Metallica bassist Robert Trujillo.[25](https://eltonsounds.com/wp-content/uploads/2016/03/web-claypool.pdf) • [2](https://redlightmanagement.com/artists/les-claypool/)
## Recent activity
In late 2024 Primus's eighth drummer quit shortly before the band's traditional Bay Area New Year's Eve shows, prompting a public drummer search called the Primus Interstellar Drum Derby that drew over 6,100 submissions; John Hoffman joined the band, which is now working on new material.[13](https://www.arcamax.com/entertainment/entertainmenttoday/s-4242994) • [12](https://bassmagazine.com/issues/issue-17/les-claypool-gold-rush/) In 2026 Claypool toured with the Claypool Gold triple bill, performing distinct sets each night with Primus, the Frog Brigade, and the Claypool Lennon Delirium, with cross-project collaborations and sit-ins.[14](https://relix.com/features/detail/claypools-golden-caravan) • [26](https://jambands.com/news/2026/07/08/claypool-gold-comes-to-a-close-on-july-4/) Beyond music, his ventures include Claypool Cellars winemaking, the Pachyderm bass company, a graphic novel, and, by his own account, a gold mine in the northern California mountains.[12](https://bassmagazine.com/issues/issue-17/les-claypool-gold-rush/)
## Influence
Rolling Stone's list of the 50 greatest bassists credits Claypool with having "liberated the bass from simply holding down the bottom," and a history of slap bass notes that he inspired millions of people to pick up the instrument.[27](https://au.rollingstone.com/music/music-lists/50-greatest-bassists-of-all-time-13565/) • [28](https://static1.squarespace.com/static/5f9d855806e786235f67b176/t/61c15e65be0aac63d14375f9/1640062565946/The%2BHistory%2BOf%2BSlap%2BBass%2B.pdf) Commentators assessing famous bassists have argued that his playing can be recognized within seconds, a distinction attributed less to raw technique than to an unmistakable musical identity.[29](https://glasp.co/youtube/EWF5IyG0rk0)
