South London's eagerly anticipated 2026 cultural calendar has received its first major announcement, with electronic music duo Overmono confirmed as the inaugural act for the Labyrinth on the Thames festival. The event, set against the historic backdrop of the Old Royal Naval College in Greenwich, will kick off in August with a special focus on community engagement through discounted and free tickets for local residents.
Exclusive UK Performance and Local Benefits
Overmono, comprising brothers Tom and Ed Russell, will take to the stage on August 7th for what promises to be their sole UK performance in 2026. Following a standout year in 2025 that included celebrated appearances at Glastonbury and All Points East, plus a sold-out show at Alexandra Palace, the duo's return to London is highly anticipated.
In a generous move for the community, festival organisers have unveiled a tiered ticketing scheme for residents. Those living within half a mile of the Old Royal Naval College site can apply for discounted tickets, while individuals residing on the immediate perimeter are eligible for complimentary admission by contacting the festival directly. This initiative underscores the event's commitment to embedding itself within the local area.
Festival Details and Line-up Curation
Labyrinth on the Thames 2026 is an open-air series dedicated to contemporary music, spanning the first three weekends of August. Each date is uniquely curated by its headlining artist, with Overmono personally selecting the supporting acts for their August 7th showcase.
The day-long event, running from afternoon until 11pm, will feature a meticulously crafted line-up that reflects Overmono's diverse sonic influences. Attendees can expect performances from Erika de Casier, Nick Leon & Verraco b2b, Loukeman, Carista, and the enigmatic Leod. This carefully assembled bill aims to transform the 17th-century riverside landmark into a vibrant 21st-century dance destination.
Ticketing and Festival Expansion
General admission tickets for the festival are yet to be released, but pre-sale tickets will become available on Thursday, January 28th, at 10am. The festival recently secured its licence nine weeks ago, with eight concerts scheduled across August's initial weekends. Plans are already in place to expand to nine events in 2027, indicating growing ambitions for this new cultural fixture.
Overmono's Rising Profile
Founded in Wales in 2015, Overmono have steadily ascended to become one of the UK's most memorable live electronic acts. Their 2023 debut album, Good Lies, received widespread critical acclaim, introducing standout tracks like "So U Kno" and "Blowout," alongside collaborations with artists such as Fred again.., Lil Yachty, and Kwengface.
The duo's creative reach extends through frequent collaborations with house musician Joy Orbison on singles including "Bromley," "Still Moving," "Blind Date," and "Lippy." Their cover of High Contrast's "If We Ever" in August 2025 further cemented their status as a festival favourite, resonating strongly with audiences across the summer circuit.
As Labyrinth on the Thames prepares to launch its inaugural series, the announcement of Overmono as the opening act sets a high standard for contemporary music programming in South London. With its community-focused ticketing and historic setting, the festival promises to be a highlight of the 2026 cultural season.
