They’re Gonna Be Big will spotlight the underground rock scene on October 28, 29, and 30, 2025, for the second edition of the festival! The Supersonic team invites you to dive into the international DIY scene and discover 21 emerging bands, all hand-picked favourites — and none of them have ever played in Paris before! Hailing from Texas, New York, Switzerland, and all across England, these bands will be performing for the very first time in front of a Parisian audience.
This intimate gathering will unfold in the Supersonic neighbourhood, across its two concert venues (Supersonic Club and Supersonic Records) and the nearby cellar space at La Seine Café.
Three days of discovery, connection, and the thrill of seeing your next favourite band before anyone else — that’s what They’re Gonna Be Big promises on October 28, 29, and 30, 2025.
Tickets : 18€ - 22€ per day / 39€ for 3 days pass
