Friday, September 25: Undercard Highlights Before Dave Matthews Band
1. Sons of Legion
Sons of Legion are a rising rock outfit slotted into the Friday undercard ahead of Dave Matthews Band. Their placement on the Friday bill at Oceans Calling 2026 puts them in front of one of the festival’s largest single-day crowds. The band’s sound sits at the intersection of arena rock and melodic songwriting, which fits a Dave Matthews Band audience that favors dynamic, guitar-forward performances.
Live, Sons of Legion focus on energy and crowd engagement, qualities that festival bookers identify as essential for mid-tier acts trying to convert unfamiliar audiences into long-term fans. Because they already show these strengths on tour, a strong Friday set could lead to touring offers and return bookings at similar coastal festivals.
2. King Stingray
Where Sons of Legion bring arena-rock energy, King Stingray offers something more culturally distinctive. The Australian indie-rock band blending surf-rock with Yolŋu language and culture brings a genuinely unique sound to the Friday lineup. Their debut album drew significant international attention, and their Oceans Calling booking reflects growing North American interest in globally rooted rock acts. World and global genres, including artists with strong cultural identity, grew listenership by approximately 26.2% in recent years, which positions King Stingray well for audience crossover.
Their live show leans on communal energy and rhythmic momentum, traits that land especially well on outdoor stages. Fans who enjoy Dave Matthews Band’s genre-blending approach will likely see King Stingray’s set as a natural complement.
3. Linka Moja
Linka Moja brings one of the more adventurous sounds to the Friday bill. Their inclusion alongside Sons of Legion and King Stingray on the Friday undercard signals a deliberate effort to diversify the day’s sonic palette. Their genre-blending style and focus on live instrumentation make them a strong candidate for accidental discovery by early-arriving Dave Matthews Band fans.
Genre fit matters more than festival size when selecting bookings, since a festival that matches an artist’s audience is more valuable than a larger event on a mismatched side stage. Linka Moja’s mix of groove-driven arrangements, organic instruments, and melodic hooks lines up with the tastes of many Dave Matthews Band listeners, which suggests real audience overlap.
4. Shwayze
Shwayze is a California-based artist whose coastal hip-hop and reggae-inflected sound matches the Oceans Calling atmosphere almost perfectly. With a catalog stretching back over a decade, Shwayze holds an interesting spot in the lineup: established enough to carry name recognition yet still pushing into a new chapter of career momentum. Their Friday slot connects them with a beach-festival crowd already primed for their laid-back, sun-ready sound.
Live performance has always sat at the center of Shwayze’s appeal, and a festival setting amplifies the communal, feel-good energy their music creates. After seeing an artist perform live, 31% of survey respondents went on to see the artist again, a metric that shows how a well-executed festival set can pay off long after the weekend ends.
Saturday, September 26: Undercard Highlights Before Twenty One Pilots
5. Goldford
Goldford stands out as one of the most closely watched names on the Saturday bill. Relix specifically calls out Goldford as part of the “new blood” on the Saturday lineup, which signals genuine editorial interest rather than a routine listing. Their atmospheric pop production and layered vocal arrangements align well with a Twenty One Pilots audience that values emotional depth and ambitious sound design.
Chartmetric’s analysis of Coachella found that several of the biggest Spotify streaming gains came from artists deep in the undercard, not just top-billed names. Goldford is well-positioned to mirror that pattern at Oceans Calling, given the size and engagement level of the Saturday crowd.
6. Cassandra Coleman
Cassandra Coleman brings a folk-influenced, emotionally direct songwriting style to Saturday’s undercard. Her placement alongside Goldford on Saturday positions her as part of a deliberate curatorial pairing of emerging voices ahead of Twenty One Pilots. Her voice and compositional choices reward attentive listening, which makes her an ideal early-set discovery for fans who show up before the main rush.
A well-balanced festival lineup blends the familiarity of established acts with the excitement of new talent, while an over-reliance on established acts without fresh voices can make a festival feel stale. Coleman’s booking directly supports that balance by adding a quieter, songwriter-driven moment to a high-energy day.
7. KT Tunstall
KT Tunstall brings proven festival experience to the Saturday undercard while still building new momentum. Known for her loop-pedal live technique and anthemic songwriting, Tunstall’s set often feels like a masterclass in solo performance craft. Her inclusion in the Saturday undercard at Oceans Calling 2026 reflects her continued relevance in the festival circuit.
Festival programmers evaluating mid-tier acts look at regional audience concentration, recent press coverage, release cadence, and documented momentum, and Tunstall continues to perform strongly across those measures.

Sunday, September 27: Undercard Highlights Before Mumford & Sons
8. Nat Myers
Nat Myers is the Sunday undercard act with the clearest alignment to the Mumford & Sons headliner. His placement on the Sunday bill at Oceans Calling 2026 puts him directly in front of the festival’s folk and Americana-leaning audience. Myers draws on blues, country, and roots traditions, delivering a raw, instrument-forward live experience that suits the reflective tone many Sunday crowds bring.
A standout festival set at a discovery stage can lead to touring offers, international bookings, label invitations, and future festival curation the following year. Myers’s Sunday slot at Oceans Calling offers exactly that kind of high-visibility opportunity.

Frequently Asked Questions
What time do emerging artists typically perform at Oceans Calling?
Undercard and emerging acts at Oceans Calling generally perform in early afternoon to mid-evening slots, before the headliner takes the main stage. Arriving two to three hours before the headliner’s set time is the most reliable way to catch the full undercard. Specific set times usually appear one to two weeks before the festival.
How do I discover more about the emerging artists on the Oceans Calling lineup?
OnesToWatch publishes in-depth artist features, curated playlists, and yearly selections that cover hundreds of emerging artists across genres. Their editorial pipeline follows artists from early discovery through touring-artist status, which makes it a reliable source for pre-festival research. Streaming platforms and artist social media accounts also help you build familiarity before a live set.
What is the difference between a legacy headliner and an emerging undercard act at a festival like Oceans Calling?
Legacy headliners such as Dave Matthews Band, Twenty One Pilots, and Mumford & Sons are booked primarily for ticket sales and broad audience familiarity. Emerging undercard acts are selected for trajectory, including streaming growth, recent album releases, tour support slots, and live performance potential. The undercard is where discovery happens, and many artists who appear on undercards today will headline comparable festivals within three to five years.
Are there other festivals in 2026 where I can see similar emerging artists?
Several major festivals in 2026 feature undercard lineups with artists at similar career stages. Lollapalooza, Electric Forest, and Coachella all showcase comparable emerging talent. Lollapalooza 2026, for example, includes undercard artists such as Lil Uzi Vert, Turnstile, Sombr, Beabadoobee, Ethel Cain, Geese, and Wet Leg. OnesToWatch’s yearly artist selections and curated playlists provide a consistent cross-festival discovery resource regardless of which events you attend.
How does attending a festival undercard set compare to discovering artists through streaming?
Live performance converts listeners into fans at a much higher rate than algorithmic streaming recommendations. A OnePoll survey found that seeing an artist perform live turned 29% of attendees into fans, compared with just 5% for algorithmic recommendations. Festival undercard sets work especially well because they expose artists to audiences who did not specifically seek them out, which creates genuine discovery moments that streaming rarely matches.
