Set inside one of the historic towers of Warsaw’s Poniatowski Bridge, Mastak is an intimate underground club and home base for an independent vinyl label. More than a club, it functions as a cultural venue, record store, educational space and meeting point for Warsaw’s creative underground. Across three parties a week, music and counterculture film screenings, workshops and community-led formats, Mastak connects DJs, diggers, musicians, artists and local voices shaping the city’s underground scene.
