**CATHARTICA PRESENTS:** # OSTROM SHOWCASE A new season. A new chapter. A new world to enter. On **21.11.2026**, we open the club season with something we have never done before. For the first time, CATHARTICA brings an international showcase to Bulgaria. We are taking over **Club K.U.P.E** and transforming it entirely into the dark, ritualistic world of **OSTROM** — candles, chains, industrial structures, and an atmosphere designed to pull you into another reality. **TWO STAGES. RUNNING SIMULTANEOUSLY.** **INDUSTRIAL HALL** — uncompromising industrial pressure, heavy kicks, and five international artist debuts in Bulgaria. **HYPNOTIC TUNNEL** — a new dimension of CATHARTICA, exploring groove, hypnotic rhythms, and deeper, rolling sounds while keeping the same dark spirit alive. **INDUSTRIAL HALL** - 5OGOL (IR) - BHX4400 (UK) - SULFIDE (HU) - KASSIS (LIVE) - GØBLIN - VAYROX **HYPNOTIC TUNNEL** - WËBER B2B V I K B (HU) - LYNN B2B BONNY - SXBER - ADD We believe in building a culture, a community, and a place we can all call our own. That's why we want everyone to be part of this new chapter. **VERY EARLY BIRDS — ONLY €10.** **Early bird tickets are available NOW.** Club K.U.P.E 21.11.2026 Two stages. One family. A completely new CATHARTICA experience. **WELCOME TO OSTROM.**
