Outbreak Festival 2026 is filled with nostalgia. There is of course the usual array of hardcore and metal bands – some of which are at the genres’ vanguard – but the occasion has an altogether retrospective feel. A staggering number of the weekend’s performances revolve around album(s) shows, with The Front Bottoms, Balance & Composure, Alexisonfire, Touché Amoré and Hatebreed all billed as such.
