Working Hard Fest, a new two-day indoor festival curated by Sofia's Threechords Records, will open at Mixtape 5 on 26-27 November 2026. The first edition splits into The Slow Burn on 26 November (Picastro, COME, Puta Volcano) and Full Throttle on 27 November (Mayak, Truckfighters, plus one act to be announced). Truckfighters, the Swedish stoner-rock band formed in Orebro in 2001, headline the heavy night; the group returned from hiatus in 2019 and remains a mainstay of European fuzz rock. Tickets are on sale via Bilet.bg, with a two-day combo at 50 EUR. The festival is Bulgaria's latest addition to the heavy-psych and stoner-rock calendar.
