10 Undercard Acts You Shouldn't Sleep On

The fact that Little Simz is on the undercard is arguably the biggest scheduling gift of the entire festival. The London rapper has a Mercury Prize, near-universal critical acclaim, and albums like Sometimes I Might Be Introvertthat rank among the best rap records of the decade. Her live show mixes bars, live instrumentation, and theatrical staging. She won't be on undercard bills much longer — catch her while the stage is still small enough to feel intimate.

Wolf Alice has two Brit Awards, a Mercury Prize nomination, and three albums that span shoegaze, grunge, folk, and indie rock without ever feeling scattered. Blue Weekendis a masterclass in dynamic range — tracks shift from whisper-quiet to stadium-loud in ways that hit harder live. Ellie Rowsell's vocals carry raw emotion, and the band plays with a tightness that comes from years of touring. One of the most complete rock bands working today, playing a stage that should be three sizes bigger.

Paris Paloma writes folk songs that cut. Her track "labour" went viral for its unflinching take on emotional labor in relationships, racking up hundreds of millions of streams. But she's more than one song — her catalog is full of richly arranged, lyrically sharp folk-pop that draws from traditional storytelling traditions while feeling entirely contemporary. Her voice is striking, and early-day acoustic sets at festivals often produce some of the most memorable moments.

Momma sounds like the best parts of 90s guitar rock filtered through a modern indie lens. Their album Household Namechannels Veruca Salt, Liz Phair, and The Breeders with hooks that stick for weeks. Dual vocals from Etta Friedman and Allegra Weingarten give their songs a texture that most guitar bands can't replicate. If you're at Lolla for the rock, this is your Saturday afternoon anchor.

CMAT (Ciara Mary-Alice Thompson) is an Irish singer-songwriter who blends country, pop, and folk with a wit and charisma that's impossible to ignore. Her debut album If My Wife New I'd Be Dead is one of the most entertaining records to come out of Ireland in years — funny, heartfelt, and musically unpredictable. Live, she's a force: all energy, audience banter, and genuine joy. One of those artists where even people who don't like the genre walk away as fans.

Quadeca started as a YouTube rapper and has evolved into one of the most boundary-pushing young artists in hip-hop. His album I Didn't Mean to Haunt Youis a genre-defying project that blends glitchy electronics, ambient textures, hip-hop, and singer-songwriter vulnerability into something genuinely new. He's an artist in constant evolution, and his festival sets reflect that ambition — expect the unexpected.

Mother Mother has been making music for nearly two decades, but a TikTok-driven resurgence brought tracks like "Hayloft" and "Burning Pile" to a massive new audience. The Canadian band's catalog is deep and consistently strong — theatrical indie rock with vocal harmonies, off-kilter arrangements, and lyrics that balance darkness with playfulness. Their live show has the energy of a band experiencing a second act and loving every minute of it.

Oklou (Marylou Mayniel) makes electronic music that feels like stepping into a dream. Her production blends delicate vocals with glitchy, atmospheric beats that draw from PC Music, ambient, and French pop traditions. She's been a collaborator and presence in the experimental electronic world for years, and her live sets create immersive sonic environments. If you want something genuinely different from the main-stage EDM sound, Oklou delivers.

Water From Your Eyes makes music that resists easy categorization. Their album Everyone's Crushed careens between noise-rock, post-punk, electronic experimentation, and pop hooks, sometimes within the same song. Nate Amos's production is restless and inventive while Rachel Brown's vocals ground the chaos with an almost deadpan cool. They're the kind of act that divides a crowd and rewards the curious. If you want to see something you can't see anywhere else on the lineup, this is it.

Spacey Jane is one of the biggest indie bands in Australia, and they're overdue for a breakout in the U.S. festival circuit. Their sound is sun-drenched indie rock with soaring choruses and guitar tones that shimmer — think early Tame Impala energy crossed with The War on Drugs' sense of scale. Tracks like "Booster Seat" and "Lots of Nothing" are the kind of songs that sound like they were written to be screamed back at a stage by thousands of people. An afternoon set from Spacey Jane could be one of the highlights of your Saturday.
