Spencer Seim is an American guitarist best known as one half of the influential math-rock duo Hella. Born on January 28, 1981, he built a reputation for unconventional, technically demanding guitar playing that helped define an entire corner of instrumental rock. Along with Hella, he drums in the Nintendo-cover project The Advantage and records solo material under the name sBACH.
Seim’s career runs through Sacramento’s noise-rock scene of the early 2000s, a stretch of national indie-label releases, and a handful of memorable pop-culture cameos, including a bit part on The Eric Andre Show. He’s not a mainstream celebrity, so a lot of the “gossip” search terms attached to his name — net worth, spouse, height — simply don’t have reliable public answers, and this article won’t pretend otherwise.
What follows covers his biography, his main projects, his gear, and the handful of verifiable facts search engines surface most often, sourced from Wikipedia, AllMusic, Equipboard, and contemporary music press.

Who Is Spencer Seim?
Spencer Seim is best known as the guitarist in Hella, an American math rock band from Sacramento, California, whose primary members are Seim on electric guitar and Zach Hill on drums. As teenagers, Seim and Hill were both members of a Northern California band called Legs on Earth, playing alongside Josh Hill and Julian Imsdahl.
That early partnership set the template for his career: a guitarist working almost entirely in duo or small-group settings, built around speed, odd time signatures, and an unusually busy, percussive style of playing.
Hella: Formation and Career
Hella came together in the spring of 2001, building a following around Sacramento before signing to 5 Rue Christine Records. Their 2002 debut, Hold Your Horse Is, established the band’s chaotic approach to instrumental noise rock.
The lineup expanded and contracted over the years. After 5 Rue Christine folded, the band moved to Ipecac Records and briefly grew to a quintet with singer Aaron Ross, guitarist Josh Hill, and bassist Carson McWhirter for the 2007 album There’s No 666 in Outer Space. By 2009 Hella had returned to its original two-person lineup, and in 2011 released Tripper on Sargent House. Following that release, the band went on what appears to be an indefinite hiatus.

The Advantage and sBACH
Alongside Hella, Seim is a drummer for The Advantage, a Nintendocore band blending math rock with rock arrangements of classic video game music, formed when Seim joined high-school friends Carson McWhirter, Ben Milner, and Nick Rogers, later joined by Robby Moncrieff.
He also records solo work under the name sBACH. The sticker on the self-titled sBACH release reads “a thousand times better than Hella or The Advantage,” a tongue-in-cheek line that’s become one of the more quoted bits of Seim trivia.
Solo / side releases include:
- sBACH (2008, Suicide Squeeze)
- Grok (2011, Jackpot Records)
- Beast of Both Worlds (2012, Joyful Noise Recordings)
- Here in Dead Lights (2018, Joyful Noise Recordings)
- SoloS (2020, Dowd Records)
Gear: Guitars, Amps and Setup
Seim is known in guitar-gear circles for playing highly customized instruments rather than off-the-shelf models.
Guitars:
- A Series 10 Telecaster copy (“Flowercaster”), a paisley-finished single-coil guitar used for aggressive playing techniques
- Scott French SF3 and SF0SS models — custom instruments featuring a nut pickup, a built-in amplified egg shaker, and individual outputs for each string pickup, with the SF0SS finished using Seim’s own beard clippings
- A eucalyptus-and-walnut Scott French guitar bought in February 2006, which was the only guitar he used on Hella’s 2007 record There’s No 666 in Outer Space
Amps: His gear list centers on a Mesa/Boogie Mark III amplifier and a Marshall JCM800 2203 head with a Marshall 1960A 4×12 cabinet. Community-sourced gear pages (Equipboard) describe a relatively minimal pedal setup by design — Seim favors amp-driven tone over heavy effects chains.
Spencer Seim and The Eric Andre Show
One of Seim’s more unusual credits is a musical cameo on The Eric Andre Show. Show creator Eric Andre explained that Seim — Hella’s guitarist — filled in on drums for a closing-credits sketch because Zach Hill, the band’s usual drummer, was on tour with Death Grips at the time. The bit paired Seim with Pete Newsom (Joanna Newsom’s brother) as a pair of free-jazz drummers behind Andre.
This is the extent of any confirmed Spencer Seim–Death Grips connection: the link runs through Zach Hill’s touring schedule, not through Seim performing with Death Grips himself.
Spencer Seim Current Status
Hella has been effectively inactive as a touring/recording act since 2011, though the members haven’t announced a formal breakup. Seim continues to be active through The Advantage, sBACH, and occasional session and side projects, largely operating outside major-label or mainstream press coverage — which is why detailed current biographical data (income, relationship status, exact whereabouts) isn’t publicly documented.
