Castlefest 2026 - Friday

Kick off your weekend with a massive night of live alternative and rock music as CASTLEFEST returns to The Castle in Luton! Headlining the Friday session are alternative rock icons INME. Armed with an arsenal of anthems spanning over two decades - from their seminal debut Overgrown Heart to their fiercely powerful recent tracks - InMe are legendary for their explosive, emotionally charged live performances. This is a rare chance to see them command an intimate stage with the raw energy they are famous for. Joining them is an incredible undercard of heavy-hitting talent: LO RAYS – Bringing their signature high-octane blend of atmospheric synths and crushing alt-rock riffs. THE INJESTER – Expect a dark, theatrical, and genre-bending spectacle that will completely captivate the room. ATLAS & I – Delivering soaring, intricate melodic rock to set the perfect tone for the night. PLUS MORE TBA... We’re not done yet. Stay tuned as we reveal even more stellar acts joining the Friday lineup.
