"That was a very strange show, because of what was happening," she recalls. "I was on tour with Cult of Luna and Intronaut. We started in February and were in 'tour-land,' so you're kind of in a bubble, where the outside world doesn't really exist and the escalation of the virus—that news wasn't impacting us. We weren't seeing it, but by the time we got to Los Angeles ...," she drifts off, the disbelief still palpable. "I'm from L.A. I was born and raised there, and driving into Hollywood, the streets were fucking empty."

"Showing up with an electric guitar and no effects is my version of the nightmare people have where they go to school with no clothes on."

Riding into an upscale ghost town sounds like an apocalyptic scenario—especially when your livelihood depends on audiences. But the adaptability of Rundle, who recorded during the lockdown and recently released an album and an EP, has been a hallmark of her career. The 37-year-old rose to prominence in the early 2000s with the Nocturnes, a folkgaze ensemble blending chamber-pop, goth, and post-rock elements into the genre. Albums like A Year of Spring (2009) and Aokigahara(2011) spotlighted her as one of the millennium's most inspired rock singer-songwriters. While in the Nocturnes, she branched out to work with post-rockers Red Sparowes, and in 2012 forged a more-straight-ahead rock collaboration under the Marriages moniker with Sparowes bassist Greg Burns. In between her musical partnerships, the prolific Rundle has also released four dazzling solo albums.

A common thread through all of her recordings is her passion for the craft of guitar playing. And her thirst for the new is reflected in that, too. With On Dark Horses, she first delved into baritone guitars—their shadowed tones magnifying Rundle's already somewhat foreboding, light-versus-dark aesthetic. From succinct to bombastic, weighty to crushing, and nuanced to vulnerable, her playing—particularly her baritone-derived soundscapes—toes the line between lilting and bludgeoning.

Emma Ruth Rundle & Thou - The Valley (Official Audio)

TIDBIT: Rundle's open baritone tuning differs from Thou's G# standard, but all four guitars on their collaborative album mesh thanks to smartly varying parts and the work of producer/engineer James Whitten.

Rundle's pair of recent recordings, late 2020's May Our Chambers Be Full and the new The Helm of Sorrow EP, mark yet another collaboration—this time with Louisiana sludge-metal lords Thou. Although Thou already had three guitar players, these releases are a perfect refuge for Rundle's low-tuned 6-strings. On Chambers'"Killing Floor," "Out of Existence," and "Magickal Cost," her playing weaves into Thou's majestic guitar tapestry as if it has always been there Meanwhile, her haunting, hypnotic vocals transcend the musical maelstrom with melodies that pierce Thou's musical armor, adding a welcome dimension to their muscular riffing. Check out Helm of Sorrow's cunning cover of the Cranberries' "Hollywood" for a slice of that sublime magic.

The Rundle/Thou union began with what she calls a long internet flirtation. "I've been such a massive fan," she admits. "I was listening to them a lot and tagging them on social media." Rundle, also a painter, would often listen to Thou while she worked. They finally met in 2018, backstage at the Northwest Terror Fest in Seattle. "It was so uncomfortable," she remembers. "There's a lot of them and they each have a very different flavor. Everyone's got a very different personality."

Their musical partnership with Rundle kicked off when, in April 2019, Thou was invited to be the artists-in-residence at the Roadburn Festival in the Netherlands. Artists-in-residence perform a collaborative set with an artist of their choosing, so Thou asked Rundle. "That was so much fun," she explains. "I was like, 'Fuck yeah, I'm not going to miss this opportunity.' It was just such a dream come true to be asked to work with my favorite band. We had to come up with original material for a 40-minute set. That's how it started."

In preparation for Roadburn, they began meeting in New Orleans in February 2019. By then, Rundle and Thou guitarist Andy Gibbs had already been emailing ideas back and forth. "It started like a riff here, a riff there," she recalls. "KC [Stafford, guitar/vocals] came into the project with 'Monolith,' which they had written pretty much all the way through. We just fleshed it out." Rundle says the songwriting process was very involved and thinks maybe her Thou cohorts were a bit surprised by her level of commitment. "I think some of their other collaborations were just … expedient," she surmises, carefully choosing her words. "Whereas we were really crafting full songs from absolutely nothing."

"Because I play in a different tuning than everyone else, sometimes I couldn't play the same riffs as them—the voicing would be really strange."

Before heading off to Roadburn, Thou and Rundle embarked on a short tour to warm up for the festival. Rundle performed solo as an opener, and Thou would play their own set, and every few nights they would inject their collaborative performance. "It was like, if the final album is a sculpture that's realized, where you can see features and details, what we had by the time we got to Roadburn was just a lump of clay," she admits. "I recently heard the set from Roadburn, and I can tell I was totally making things up that just sounded like words. [laughs]. It evolved a lot more after we played that set."

A lot of Thou's mighty sound relies on the number of guitars playing the same down-tuned riff. In addition to Gibbs and Stafford, the band includes Matthew Thudium on guitar and Mitch Wells on bass, so fitting into that heavy alignment provided some challenges for Rundle. She says they made it work with the help of producer/engineer James Whitten, who she refers to as Thou's secret weapon. He recorded both May Our Chambers Be Full and The Helm of Sorrow at High Tower Music in New Orleans."

James is a genius with guitar tone and with finding a place for all of the guitars," Rundle says. "There is some mystery and mystique to his method. There's no way to have four guitars happening all the time and have it sound that good. I think he's doing some magic and picking and choosing. It was a surprise to hear what moments came out."

It's worth noting that Rundle plays in a different tuning than the rest of Thou, which further complicated how the guitars intermingled. The tuning on Rundle's baritone is G#–C#– G#–A#–C#–G#—an open tuning that lets her barre chords with a single index finger. Thou's tuning, according to Gibbs, is G# standard, just like standard tuning, except the lowest string is G#. "The process went like this," Rundle says. "There would be basic riffs. We would all learn them together, and that would form the basis of the song. But because I play in a different tuning than everyone else, sometimes I couldn't play the same riffs as them—the voicing would be really strange." In some cases, Rundle says it also just didn't make sense to have four guitars and a bass player playing the same drop-tuned riff together. So sometimes she would play other parts. "It made sense to have a little lead melody happening or a different chord voicing," she says. "That's how we made it work. There are times where I'm playing the same 'sort-of' riffs, but there are a lot of moments where it's either a finger-picked thing or a little lead line."

Emma Ruth Rundle Rig Rundown

Exclusively a fingerstylist, Rundle uses acrylic nails to pluck her primary guitar, a Fender Jaguar Special Baritone HH. "They don't make it anymore," she relates, "but it has humbuckers, which is the reason why I really love it. That specific model was what got me into playing baritone guitars."

Because the baritone is "pretty wonky" intonation-wise, Rundle also wields a Gibson SG Special, a Guild S-200 T-Bird (both in C# tuning), and a new Dunable Yeti that was custom built for her by Intronaut's Sacha Dunable. "With the Fender, you can't get the intonation right," she says. "It's just the nature of the scale length—and then I'm doing drop-tuning on a drop-tuned instrument! It's flawed in so many ways." [Editor's note: The Jaguar Special bari has a 27" scale, whereas "true" baritones are typically 28" or more in order to intonate more accurately across the fretboard.] Ultimately, she concludes, "I just don't think you can beat an SG." She says that instrument's fretboard reminds her of the classical guitars she learned to fingerpick on—and that she still uses to write and practice on. "To me, the SG is the perfect guitar."

In addition to the baritone, effects are crucial to Rundle's sound and style. "I consider my pedalboard an instrument that I wouldn't want to do any of this stuff without. It's like a palette of tones and effects that you know will work in any given situation. After a certain amount of time, you just know when something has to have a super-hot fuzz with an octave on it for it to cut through at the right moment and make sense. And if I have an EBow, I know it's always going to go with either a slide or a really slow delay."

Rundle says her fascination with effects and electric guitar playing happened in parallel. "I got a multi-effects pedal with my first guitar. I think showing up with an electric guitar and no effects is my version of the nightmare people have where they go to school with no clothes on," she laughs. "It's not a place I want to be, you know?"

Speaking of school, it was while working a 13-year stint at McCabe's Guitar Shop, a folk music center in Santa Monica, California, that she received her informal musical education. "We sold instruments, we had concerts, and we had lessons. A lot of the things that I've learned that have made their way into my playing just came from the people there—the teachers that would come down. Pete Steinberg is an amazing, award-winning finger picker, and he'd just be like, 'Come over here. I'm going to show you something.'" And on the rock side, she credits the inspiration of Jimi Hendrix, Billy Corgan, Kurt Cobain, Courtney Love, P.J. Harvey, and, especially, Nancy Wilson.

"I had this revelation when I learned about Heart. It blew my mind—just seeing a woman shred like that. I felt, when I was super young, that I didn't see myself reflected in guitar magazines or in rock music, necessarily. I'm stoked that we don't have the 'bikini-fashion-show-guitar-thing' anymore, you know what I mean?"
