Old friends, new sounds, and a true December groove - the duo OT&DO and the project Roz Vitalis are back on stage together. Two recognizable musical styles intertwine into one live story: there is both philosophical depth and the energy of a real jam. When two original groups unite on one stage, it is always an event. Roz Vitalis and OT&DO are collectives that need no further introduction for those who follow intellectual and progressive music. Their joint December concerts have already become a tradition, but each time they sound new. This year, everything revolves around the image of "Pull-Push" - a metaphor for balance, confrontation, and interaction. Roz Vitalis is a musical project that is hard to fit into genre frameworks. From post-rock to neoclassicism, from jazz to experimental rock - each of their sets turns into a rich journey with a philosophical subtext. Their music is built on dialogues - of instruments, moods, cultural codes. OT&DO is a duo that always plays on the edge between street sound and refined improvisation. Their live performances are not just a show, but a true performative exploration of the interaction between people and sounds. Everything can be here: scratching, sampling, synths, and lyrics that resonate with honesty. Other events in Saint Petersburg can be found on KudaGo.
