TGBB Festival 2026 : Jour 3

For its third edition, They're Gonna Be Big is more than ever set to live up to its name, bringing together the cream of the global indie and alternative scene.

Thursday 29 October 2026 (19:00-00:00)

Peer Pleasure (Post-Punk - Wexford, IRL)

Peer Pleasure, who have played the New Colossus and Irish Music Week, turn chaos into a cocktail of noise, blues, garage and punk, driven by absurd humour. Born out of a lockdown project that became a dysfunctional family, the Irish group mixes biting cynicism, frustration and acerbic criticism. FFO: Viagra Boys, Deadletter & Opus Kink

Mouth Ulcers (Goth/Post-Punk - London, UK)

Post-punk with tribal percussion and a cavernous baritone voice is what Mouth Ulcers, signed to LAB Records, has to offer. The London quartet, who have played the Grauzone Festival and Left Of The Dial, draw on the legacy of The Cure and Bauhaus to craft music that is at once dark, physical and infectious. FFO: She Past Away, Rendez-Vous & Soviet Soviet

lttl mort (Indus/Synthwave - London, UK)

With an electronic euphoria, the British project lttl mort swings between mechanical precision and emotional excess. Industrial synthwave that is as danceable as it is unsettling, capturing the intoxication of the night as well as the emptiness of the morning after. FFO: Nine Inch Nails, Health & Twin Tribes

Accessory (Indie Pop - Chicago, USA)

Behind the experimental pop project Accessory is Jason Balla (a member of Dehd), who explores the fault lines of communication, desire and contemporary uncertainty, all between tenderness and tension. FFO: Alex G, Dehd & Mitski

Insider Trading (Art Rock - Edinburgh, UK)

Insider Trading, the Edinburgh quartet who headlined Sneaky Pete's, win people over with their post-rock, post-punk sound and Midwest emo and slowcore influences. FFO: Maruja, Model/Actriz & Geese

CABL (Indie Rock - Dublin, IRL)

CABL blurs the boundaries between shoegaze, emo and indie rock. The band, who have supported Pillow Queen, Ulrika Spacek and Robocobra Quartet, transform stories of addiction, family fragility and mental health into songs that are as abrasive as they are moving.
