Festival announcement season rolls on, and Rock en Seine has just pulled in nearly thirty new names for its 2026 edition, doubling the number of artists set to play the Domaine national de Saint-Cloud from Wednesday 26th to Sunday 30th August.

Joining previously announced headliners The Cure & Deftones is a stacked alternative announcement led by Scottish post-rock institution Mogwai, London’s Wolf Alice, and art-pop veterans Sparks, with the Mael brothers now closing in on 60 years of gloriously eccentric output. Experimental rock outfit Black Country, New Road are also confirmed, alongside Swedish composer Anna von Hausswolff, who continues her gothic-drone work with her trusted pipe organ in tow.

Elsewhere, Peaches returns with her radical edge fully intact, while Kompromat, the techno-punk pairing of Vitalic and Rebeka Warrior, bring one of French electronic music’s most electrifying live shows to the festival. Swedish artist Lykke Li and hip-hop duo Clipse, freshly reunited in 2025 after 16 years away, round out the upper tier of new additions.

The bill leans hard into emerging talent, too. UK newcomers High Vis, Sekou, TTSSFU and Man/Woman/Chainsaw have all been confirmed, alongside Irish acts Florence Road and Kingfishr, Australian artist Ecca Vandal, and a strong American contingent of Jean Dawson, Tyler Ballgame, Hudson Freeman and Love Spells.
