From grouptherapy. Collective to PARTYOF2 Duo
PARTYOF2 traces its origins to grouptherapy., a four-piece collective formed in 2019 whose original lineup included Jadagrace, SWIM, TJOnline, and Rhea. After Rhea departed in 2020 and TJOnline in March 2024, the remaining duo of Jadagrace and SWIM rebranded as PARTYOF2 as a fully realized, self-directed project. The rebrand marked a reset and a sharpening of focus. As the duo stated via Stereogum and uDiscoverMusic, the transition allowed them to become the most defined they have ever been, a core idea within the OnesToWatch selection narrative.
Jadagrace and SWIM have been close friends for more than fifteen years. Both worked in film and television as children before discovering their performance chemistry inside grouptherapy. That shared history gives PARTYOF2 a creative foundation that feels lived-in, specific, and difficult to replicate.
Career Breakthrough and Streaming Milestones
OnesToWatch notes that longtime listeners feel validated by PARTYOF2’s rise while new fans arrive in waves. The documented timeline supports that momentum. Following the rebrand, PARTYOF2 signed to Def Jam Recordings after the March 2025 release of their EP “We Owe You An Explanation.” Their debut album, AMERIKA’S NEXT TOP PARTY!, arrived in October 2025 on Def Jam and was produced and written entirely by SWIM and Jadagrace.
The album received widespread critical acclaim from Billboard, XXL, Uproxx, NPR, Complex, Hypebeast, Paper Magazine, Genius, Grammy.com, Rolling Stone, Colors, Revolt, and Pigeons & Planes, which named it one of their favorite debut albums of 2025. The lead single “POSER” has accumulated approximately 32 million streams on Spotify. Their full catalog has surpassed 58.2 million streams in total. On May 15, 2026, PARTYOF2 released AMERIKA’S NEXT TOP PARTY! (EXTENDED CUT) via Def Jam, adding three new tracks, “2 NIGHTS IN LA,” “PUNK B!TCH,” and “PLAN B,” plus an interlude to the original record.
Sound, Visual Identity, and Creative Worldbuilding
These commercial milestones rest on a foundation of adventurous, genre-blending artistry. “Complexity and synergy” define PARTYOF2’s performance art, according to OnesToWatch, and their creative process supports that description. Their sound shifts without warning between distorted alt-rap, house rhythms, dreamy synths, emotional hooks, punk-infused rap, and dance elements. That unpredictability keeps listeners engaged and fuels steady audience growth. Nylon’s April 2026 feature “The New Faces Of Party Rap” places PARTYOF2 within a new wave of acts revitalizing hip-hop, pop, and electronic music with an earnest, vulnerable approach, channeling Tyler, the Creator, Doechii, and Missy Elliott with Timbaland at any given moment.
Their backgrounds in film and television as children directly inform their confident on-camera presence, exaggerated styling, dramatic framing, and theatrical performance approach. Music videos function as surreal late-night internet universes where fashion, satire, underground rap, performance art, and online culture collide, and every detail feels intentional. The duo’s uniform-heavy visual concept and black-and-red color palette draw inspiration from the historic styling of the Black Panther Party. Their two-headed Doberman imagery reflects both political themes and the duo’s creative duality.
Releases, Cosigns, Touring, and Festivals
The OnesToWatch-curated pipeline of playlist placement, artist features, and Top 30 selection aligns closely with PARTYOF2’s rise. The duo has received cosigns from Tyler, the Creator, Missy Elliott, Doechii, Timbaland, KAYTRANADA, Anderson .Paak, and Rapsody. That level of industry validation has translated into demand for live shows across continents.
The European tour in May 2026 included Paris on May 13 and Berlin on May 18, with no London date. These club shows set the stage for a packed festival season.
The 2026 festival run then followed:
- Lollapalooza, T-Mobile Stage, Chicago, July 31
- Osheaga, Montreal, August 1
- Pukkelpop, Hasselt, Belgium, August 22
- All Points East, London, August 29

Scene Impact, Fan Culture, and Industry Standing
OnesToWatch identified that PARTYOF2’s visuals are “exploding across the internet,” a claim supported by fan behavior. At their Colours Hoxton show in London, fans arrived fully dressed in the album’s black-and-red aesthetic and spent the entire set screaming lyrics back at SWIM and Jadagrace. That crowd energy extended the AMERIKA’S NEXT TOP PARTY! world into the live space. Nylon places PARTYOF2 within the new wave of party rap, while Consequence notes editorial recognition from The New Yorker, Teen Vogue, i-D, PAPER Magazine, The Fader, REVOLT, Clash Magazine, Stereogum, FLOOD Magazine, and Billboard.
OnesToWatch produces approximately 300 artist features annually, with only around 20 artists earning a place in the yearly Top 30 selection. PARTYOF2’s inclusion represents the platform’s most concentrated editorial filter, an early industry signal that highlighted this trajectory before it reached the Lollapalooza main stage.

Current Era and What Comes Next
OnesToWatch frames this era as “only the beginning of an everlasting legacy,” and the duo’s own words echo that ambition. Jadagrace and SWIM have stated, “We’ve been going nonstop, on the road, on stage, in the gym, and in the studio. We’re hungry, we know exactly where we want to take this.” The EXTENDED CUT tracks build on the original album rather than repeating it, combining late-90s punk attitude with glossy modern club bass, with SWIM leading production alongside Martin Rodrigues, Gustav Landell, and Simon Jonasson. The duo described the extended project as “a victory lap: playful and experimental, at times chaotic, but grounded in intention, introspection, and vulnerability.”

Frequently Asked Questions
Who are PARTYOF2 and how did they form?
PARTYOF2 is a Los Angeles-based duo consisting of Jadagrace and SWIM, two close friends who have known each other for over fifteen years. Both began their careers as child actors in film and television before joining the four-piece alternative hip-hop collective grouptherapy. in 2019. After TJOnline and Rhea departed the group in 2024, Jadagrace and SWIM launched PARTYOF2 as a fully independent creative project, signing to Def Jam Recordings following the release of their 2025 EP “We Owe You An Explanation.”
What is PARTYOF2’s connection to grouptherapy.?
grouptherapy. was the predecessor collective that originally included four members: Jadagrace, SWIM, TJOnline, and Rhea. The group formed in 2019 and built an early following before lineup changes led to the departure of TJOnline in March 2024 and Rhea shortly after. Rather than continuing under the grouptherapy. name, Jadagrace and SWIM rebranded as PARTYOF2 to reflect their new direction as a duo. The rebrand allowed them to consolidate their creative vision and become a more focused version of themselves as artists.
What has PARTYOF2 released and how has it performed?
PARTYOF2 released their debut album AMERIKA’S NEXT TOP PARTY! in October 2025 on Def Jam Recordings. The album was produced and written entirely by SWIM and Jadagrace and received critical acclaim from outlets including Billboard, NPR, Rolling Stone, Complex, XXL, and Pigeons & Planes, which named it one of their favorite debut albums of 2025. The project and its EXTENDED CUT have reached tens of millions of streams across the catalog, as detailed earlier, and continue to grow.
What major festivals has PARTYOF2 performed at in 2026?
PARTYOF2’s 2026 festival run has been extensive. The duo performed on the main stage at Lollapalooza in Chicago on July 31, at Osheaga in Montreal on August 1, at Pukkelpop in Hasselt, Belgium on August 22, and at All Points East in London on August 29. These appearances followed a sold-out run of European club dates in May 2026, including Paris and Berlin, which marked their first European shows since rebranding from grouptherapy.
Why did OnesToWatch select PARTYOF2 for the 2026 Top 30 Artists to Watch?
OnesToWatch selects approximately 20 artists annually for its Top 30 list from a pool of around 300 features, making inclusion a significant editorial distinction. PARTYOF2 earned their place through several documented factors: the strength and critical reception of AMERIKA’S NEXT TOP PARTY!, the viral reach of their visual identity, the live performance intensity that has drawn dedicated audiences across the US and Europe, and a clear trajectory from small venues to major festival main stages. The selection reflects the platform’s focus on authentic, live-performance-driven artists with the potential for long-term careers.

Conclusion: A Clearly Tracked Rise
The arc from grouptherapy. to PARTYOF2 shows a steady climb from a four-piece collective navigating lineup changes to a focused duo performing on the Lollapalooza main stage one year after their rebrand. SWIM recalled meeting a fan at Lollapalooza who had last seen them in 2021 at a 50-capacity venue in New York, a moment that compresses the entire journey into a single exchange. From that 50-capacity room to a main stage festival slot, from early playlist placement to a Top 30 selection by OnesToWatch, and from a debut album praised by Rolling Stone and NPR to sold-out European dates, PARTYOF2’s path stands out as one of the clearest emerging artist stories of 2026. OnesToWatch spotlighted that path early, and the evidence has only grown stronger since.
