Main Square Festival 2027 has added Nothing But Thieves to an opening wave that already moves confidently between arena rock, electronic spectacle and contemporary pop. The festival returns to the Citadelle d’Arras from Friday, July 2 to Sunday, July 4, 2027, with Muse, David Guetta, Sombr and Angèle also confirmed.
This is not the final bill. Main Square’s official programme says more artists will follow, but the first five bookings already establish a clear shape: a pop-focused Friday, a stadium-sized Saturday dance headliner and a Sunday rock pairing built for the Citadelle.

The first five names, day by day
The initial programme is already split across all three festival days. Set times and stages have not been announced, so the schedule below reflects confirmed dates only.
Friday, July 2 – Angèle and sombr
Angèle arrives with Instinct, her third album and a fresh electronic-pop chapter featuring collaborators including Justice, Soulwax, Caroline Polachek and SebastiAn. That makes the Belgian artist a particularly sharp booking for Main Square: the new material is designed for a large crowd, but it still carries the personality and bilingual songwriting that made her one of francophone pop’s defining voices.
Sombr shares Friday’s top billing. His rise from intimate, emotionally direct songwriting to major international stages has been fast, driven by songs such as Back to Friends and Undressed. Main Square is presenting the appearance as a French exclusive, giving the opening day a booking that feels current rather than merely familiar.
Saturday, July 3 – David Guetta
David Guetta takes the Saturday spotlight. Few artists are better equipped for the scale of the Citadelle: his catalogue moves from crossover records such as Titanium to festival-sized dance releases built around immediate hooks and enormous drops. With no supporting Saturday names revealed yet, his booking functions as the first anchor for the middle night.
Sunday, July 4 – Muse and Nothing But Thieves
Muse returns to headline Sunday with the kind of theatrical rock production that suits Main Square’s biggest stage. The band’s combination of precision, distortion and spectacle has made songs including Hysteria, Starlight and Uprising enduring festival staples.
The latest addition is Nothing But Thieves, returning to Main Square three years after their previous appearance. Conor Mason’s voice gives the band a dynamic range that can move from restraint to full-force release, while the Dead Club City era pushed their alternative rock toward a more ambitious, conceptual scale. Pairing them with Muse gives Sunday a coherent rock identity without making the two bookings feel interchangeable.
Why this early wave works
Main Square has not tried to make five names look like a finished lineup. The official site is transparent that the programme is still growing, and that honesty helps the announcement land. Each day has a recognizable centre of gravity while leaving enough room for later additions to reshape the bill.
Friday can expand around pop, alternative and electronic acts. Saturday has a natural dance focal point in David Guetta. Sunday already has a strong guitar-driven spine through Muse and Nothing But Thieves. It is a compact first wave, but not a random one.
Planning for Arras
Book early – accommodation in and around Arras becomes scarce during Main Square weekend, so waiting for the final poster can reduce the practical options.
Use the official updates – day tickets are already part of the sale, but later lineup waves may affect which date works best for you.
Expect an outdoor festival – prepare for changing northern French summer weather and check the official visitor guide for the final entry, transport and bag rules closer to the event.
Do not treat this as the complete schedule – stages and performance times remain unknown, and Main Square has explicitly promised more artists.
More names are coming
The first wave gives Main Square Festival 2027 a credible start rather than a complete identity. Angèle and Sombr make Friday feel current, David Guetta supplies Saturday’s mass-audience centrepiece, and the Muse plus Nothing But Thieves pairing gives Sunday immediate weight.
