Julia Lipniewicz (Toxido Mask) is a Berlin-based DJ and producer who started making music in 2013. A resident at Tresor and frequent Berghain performer, she works across ambient, deep techno, and halftime, weaving intricate textures with industrial and natural soundscapes. Her releases appear on Semantica, Pregnant Void, and other labels, while she curates the OMM Transmission podcast and event series. Her approach emphasizes sound design precision and emotional depth rather than traditional dancefloor bombast.
