Rock en Seine 2025: Day 4 with Justice, The Psychotic Monks... we were there, we tell you all about it

After Chappell Roan, Kid Cudi and Anyma, it was Justice's turn to light up Rock en Seine! The legendary French electro duo got festival-goers dancing on the lawn of the Domaine de Saint-Cloud this Saturday, August 23, 2025. But this fourth day was also marked by sets from Pamela and The Psychotic Monks. We were there, and tell you all about it.

The penultimate day of Rock en Seine on Saturday, August 23, 2025. Before the festival closes on Sunday with the Americans of Queens of the Stone Age, the Ile-de-France festival had decided to make us dance to the electro sounds of Justice, programmed on the main stage this Saturday evening. But before we tell you all about the French duo's flamboyant show, let's look back at some great musical discoveries and a major disappointment on the fourth day of Rock en Seine at the Domaine national de Saint-Cloud.

On Saturday, before Justice 's eagerly-awaited show on the main stage, we decided to linger for part of the day in front of the Bosquet stage. Located not far from the (general public) entrance to the site, this small stage features artists less well known than the headliners, but already well established in the musical landscape or up-and-coming. This year, Rock en Scène has programmed Barry Can't Swim, Kids Return, Floating Points, Sharon Van Etten and Kneecap.

Pamela, a punchy electro-rock sound and infectious energy

This Saturday, we kick off with Pamela. Behind this name hides a duo made up of Breton Simon Quénéa, best known as Zaho de Sagazan's drummer, and Englishman Samuel Sprent, originally from Liverpool, as evidenced by the Liverpool FC scarf visible on stage. Having already aroused the curiosity of many when they opened for them at the Zénith, and prior to a concert at the Trianon in November 2025, Pamela made a stopover at Rock en Seine on August 23. A fine career for this band, who released their first EP only last March.

With their infectious energy, Pamela got festival-goers dancing in front of the Bosquet stage around 6pm on Saturday. The combo, transformed into a trio for the occasion (with the presence of a bassist), seduced our ears thanks in particular to the boundless energy of its singer, who didn't hesitate to waddle and gesticulate on stage. But Pamela 's strength lies above all in her musical style: a hard-hitting electro-rock sound, somewhere between LCD Soundsystem and Soulwax, blending heady choruses and powerful, often looped melodies. Intoxicating and simply effective!

John Maus, a disappointing one-man show

We had high hopes for John Maus' set. But the disappointment was all the greater. A few minutes before the start of the show, originally scheduled for 7.30pm, we discovered a completely empty Bosquet stage. We wondered whether the concert had been cancelled or postponed. The answer seems to be no, if we are to believe the impatient technicians at the side of the stage. It wasn't until around 7.40pm that American John Maus came running out. He retrieves a box containing his equipment from behind the stage. It took another 5 minutes or so for the artist to settle in and begin his... very atypical.

Alone on stage, John Maus screams into his microphone, while rocking back and forth and viciously banging his head and torso. We knew this show was going to be experimental, but not to this extent. It's a pity, because John Maus 's musical genre is well worth the detour, somewhere between synthpop and darkwave. John Maus seems to be more of a studio artist than a live performer.

The Psychotic Monks, an original and captivating Futur Composé creation

For their appearance at Rock en Seine, The Psychotic Monks - a talented French punk rock quartet - decided to take on an unusual challenge, designing a set for the"Colis Suspect #4" event organized by the Futur Composé association and for the Paris region festival. The idea? To propose an original collaboration with three talents from three institutions welcoming people with ASD (Autism Spectrum Disorder): Étienne from ESAT Turbulences on keyboards, Thierry Dupont from the group Ron Pon, and Markus from the Perce-Neige Alternote home on drums, who some of you may already have seen on France 2's"Les rencontres du Papotin".

Together, they treated festival-goers to an electric concert, featuring dark, inhabited rock, but also improvisation by musicians with an experimental, instinctive approach. Bravo and thank you for this wonderful musical project!

Justice, a flamboyant and luminous show to end the evening on a high note

Justice 's French Touch took center stage at Rock en Scène, bringing the August 23 event to a fitting close. And fans of the electro duo were out in force on Saturday evening, recognizable by their band t-shirts. For the occasion, the famous duo Gaspard Augé and Xavier de Rosnay brought out the big guns with a beautiful scenography and an impressive light show.

Although there were only two of them (and no microphones) on the huge festival stage, the two acolytes got thousands of festival-goers up and dancing with ease, thanks to a carefully-crafted setlist featuring their hits " Neverender ", " We Are Your Friends " and " D.A.N.C.E. ". In a set lasting around 1h20, Justice proved that they are still at the top of their game, and still know how to excel live.

Rock en Seine 2025 continues this Sunday, August 24, with acts including Queens of the Stone Age, Fontaines D.C., Last Train, Stereophonics and The Limiñanas.
