If you’ve spent any time in the indie rock world over the last decade, you know Big Thief isn't just a band. They’re kind of a religion. Or at least a very intense, sweat-soaked, emotionally raw support group that happens to play guitars. But if you’ve been paying attention lately—especially with the release of Double Infinity and their 2026 world tour—you’ve probably noticed the stage looks a little emptier.
Things changed. A lot.
The core of Big Thief has always felt like an impenetrable knot, but 2024 saw the first major fraying of that rope. Now, in 2026, the band is operating as a trio with a rotating cast of friends. Honestly, it’s a weird time to be a fan, but the music is somehow getting weirder and better.
The Current Core: Who Is Still In Big Thief?
Right now, the official Big Thief band members are Adrianne Lenker, Buck Meek, and James Krivchenia. That’s it. The "power trio" era is officially here.
Adrianne Lenker (Vocals, Guitar)
She’s the heartbeat. There’s really no other way to put it. Adrianne grew up in a nomadic, somewhat intense environment, and that "forest-dwelling" energy (as she often calls it) defines the band’s mysticism. By the time she was 12, she was playing bars. By the time she met Buck Meek in a Brooklyn grocery store (Mr. Kiwi’s, for the real ones), she was already a seasoned songwriter.
In 2026, she’s coming off the massive success of her solo record Bright Future, which snagged a Grammy nomination. But she’s always said Big Thief is her "home base." She plays a vintage Gibson ES-125 that looks like it’s been through a war, and her lyrics still feel like she’s reading your private journal out loud.
Buck Meek (Lead Guitar, Vocals)
Buck is the secret sauce. While Adrianne provides the emotional gravity, Buck provides the grit and the "twang." He’s from Texas, and you can hear it in every slide of his fingers. He and Adrianne were actually married early on in the band's history, divorced in 2018, and—somehow—remained best friends.
Most people would have quit the band. They just kept touring. Buck’s guitar work is famously "unstable" in the best way; he hits notes that sound like they’re about to fall over, but they never do. He’s also been busy with his own solo stuff, like the 2026 release The Mirror.
James Krivchenia (Drums, Producer)
James is the one who keeps them from drifting into space. He started as their sound engineer for the first album, Masterpiece, before they realized he was actually the drummer they needed. He’s also the guy who produced Dragon New Warm Mountain I Believe in You, which basically cemented them as legends.
He’s moved around a lot—New Mexico, LA, and now back to Brooklyn after his house unfortunately burned down in the Bridge Fire. You can hear that chaotic, resilient energy in his drumming. He doesn't just hit the drums; he textures them.
What Happened to Max Oleartchik?
This is the question that blew up the internet in 2024. Max was a founding member. He was the bassist who played on every single record from Masterpiece to Dragon.
Then, in July 2024, the band dropped a bombshell on Instagram: Max was out.
The statement was vague, citing "interpersonal reasons." Naturally, the internet went into a spiral of speculation. Because Max is Israeli and the band had previously faced massive backlash for booking (and then canceling) shows in Tel Aviv, many fans assumed the split was political. The band has never explicitly confirmed this, though they’ve talked about the "grief" of the breakup in recent interviews for the Double Infinity press cycle.
Adrianne described the split as a "divorce." It was heavy. For a band that marketed themselves as a "chosen family," seeing one of the pillars crumble was a shock.
The New Live Dynamic: 2026 and Beyond
So, who plays bass now?
Big Thief hasn't officially "replaced" Max. They aren't looking for a new permanent fourth limb. Instead, they’ve been leaning into a more fluid, "extended family" vibe for their 2026 Somersault Slide 360 Tour.
- Joshua Crumbly: If you’ve seen them live recently, you’ve likely seen Joshua on bass. He’s a monster player who brings a slightly different, jazzier pocket to the songs.
- The Second Drummer: Sometimes they bring out Jon Nellen to do the "Double Drummer" thing they experimented with during the Dragon era. It’s loud. It’s chaotic.
- Family Ties: Buck’s brother, Dylan Meek, has been opening shows and occasionally jumping on keys.
Basically, Big Thief in 2026 is less of a rigid quartet and more of a traveling circus. They’re leaning into the "trio" identity for recording, but the live show is whoever is around and feels the vibe.
Why the Lineup Still Works (Despite the Drama)
You’d think losing a founding member would tank the chemistry. It didn't.
Double Infinity, their first record as a trio, is arguably their most experimental. Without a permanent bassist locked in during the writing phase, the songs have more "air." There’s more room for Adrianne’s weird tunings and James’s found-sound percussion.
They’re still the same band that will stop a show to check on someone in the front row. They’re still the same band that records live in one room to "capture the ghosts."
How to Follow the Band Members Today
If you're trying to keep up with the individual Big Thief band members, here’s the best way to do it without getting lost in the weeds:
- Check the Solo Catalogs: To understand Big Thief, you have to listen to the solo records. Adrianne’s Bright Future and Buck’s Haunted Mountain are essential. They often trade songs between projects.
- Live Archive: The band is very cool about fans taping shows. Check sites like Dimeadozen or even YouTube for 2026 tour captures to hear how the new trio arrangements sound.
- Credits Matter: Look at the liner notes for Double Infinity. You’ll see James Krivchenia’s name all over the production credits. He’s the architect of their current "messy-but-perfect" sound.
The "original" Big Thief is gone, and that’s okay. Bands are living things. They grow, they shed skin, and sometimes they have to break apart to see what’s actually inside. Right now, what’s inside Big Thief is a leaner, hungrier trio that seems more committed to the "fire" of the music than ever before.
If you're heading to a show this year, don't expect a note-for-note recreation of the albums. Expect a transformation. That's always been the point.
