TSVI Ljubljana arrives through the latest edition of Submundo, bringing one of the most respected and unpredictable figures in contemporary bass-heavy club music to Slovenia for a night built around percussive pressure, rave energy and underground dancefloor experimentation.
Known both as TSVI and Anunaku, Italian-born and London-based producer Guglielmo Barzacchini has spent more than a decade shaping a sound that moves fluidly between tribal techno, UK funky, breaks, Latin-inspired club mutations and raw rave functionality. His productions have become staples within global underground DJ culture, regularly appearing in sets from some of the most forward-thinking selectors in electronic music today.
For the Submundo collective, TSVI’s sound has long held a special place, with many of his tracks already functioning as unofficial weapons across their dancefloors and radio sessions.
The TSVI Ljubljana appearance continues that relationship in full force.
Across releases on labels including AD93, Whities, TraTraTrax, SVBKVLT and his own Nervous Horizon imprint, TSVI has consistently pushed club music into unpredictable territory without losing physical dancefloor impact. His tracks pull influence from raptor house, dembow, guaracha and late-90s progressive trance aesthetics while maintaining the tension and functionality of modern underground bass culture.
Alongside solo work, his collaborations with artists such as object blue, DJ Plead, DJ Babatr and Loraine James further established him as one of the more adventurous producers currently operating across the global club landscape.
Beyond production, Nervous Horizon itself has become one of the defining underground labels for contemporary bass and hybrid club music. Co-run alongside Wallwork, the imprint has released material from names including Josi Devil, Toumba, Ma Sha, Piezo, Peder Mannerfelt and Siu Mata — artists similarly focused on pushing club music beyond conventional genre boundaries.
Supporting the night are Shizika, DJ90FIT b2b TizTiz and DJ Turbo Maximus, continuing Submundo’s tradition of connecting international innovators with local underground energy and community-driven club programming.
Lighting for the event will be handled by Nika Erjavec, adding another immersive layer to a night already centered around rhythm, movement and sensory intensity.
Submundo itself has steadily become one of the more distinctive underground concepts within the regional electronic music landscape, focusing on bass-heavy experimentation, sound system culture and club experiences designed for dancers rather than spectators.
Early bird tickets are priced at €10 in limited quantities, with presale tickets available for €13 and door entry set at €15 on the night of the event.
For fans of cutting-edge club music, broken rhythms and high-pressure bass experimentation, TSVI Ljubljana promises one of the more forward-thinking underground bookings of the month.
